140H Grader

[rc_farmer]

I am back on the grader. Here are a few pics. This is going to be a full function grader. For the controls, i will utilize a combination of air and hydraulics.....too many features to run full hydraulics. Steering will run off hydraulics and some of the blade/moldboard features. Ripper will be air. I have started "some" paint, but i have a long ways to go. I have completely changed the body of the grader. I like the hulky look of the square-back of the 140H instead of the slanted. The saddle tanks are about to primer and paint.

Enjoy,

How are you going to synchronize all 4 drive motors and be able to steer? Wasn't there a discussion about that recently? How many channels will be needed to operate a grader like this?

[Lil Giants]

I think using the "dual motor mix" with the Sabertooth might work to help it steer, as long as you're moving forward. Have you used a Sabertooth dual esc with a tracked model before Rob?

I think there's about 8 or9 hyd functions within a grader Steve... D9 Joe would know. ;)

[RCLogger]

Nice build
The four motors for the drive system is the way to go for sure, that is what I did for my ADT. Did you happen to put drive motors in the front steering wheels, it would sure help with the traction and also steering.

greg

[JAMMER]

Hey Rob looking good. I remember seeing this before but for got about it mice work keep it up. Ed

[rc_farmer]

Thanks guys for all the compliments.

I am using the Sabertooth ESC
I am not powering the front wheels.
As for the channels......whew! f/rv, steering, body swival, wheel tilt, ripper, moldboard up/dn, blade swival, blade tilt, lights, just to name a few. I am going to run hydraulics on the steering and on the moldboard. I am using air on the ripper......and figure out the rest on the fly. There are not enough channels or switches on any radio to properly run all the function on a grader......that i am aware of.

Still have a lot of work to do.

[Espeefan]

What a beast! It sure looks big compared to the 1/64 scale model. Glad to see you are moving forward with this project, Rob. Looking good.

[rc_farmer]

Here are some new pics of the saddle gas tanks.

[Blender]

Is that styrene and wood on the saddle tanks? is there some kind of advantage to doing it that way?

They look neat though.

[RAIDERS]

looking good!!!

[SmallHaul]

Looks great! What a cool model.

Are those Tamiya giant dump truck wheels & tires?

[dirtpusher9]

Looking good Rob, I'm glad your back on this build.

[td9clyde]

Jammer said he found a radio that had 22 channels on it that should be plenty lol it is in his excavator thread i think

[Tamiya Cowboy]

Wow Robbert glad to see you back at it and them rims you were not joking your buddy knocked them out very very nice..

[rc_farmer]

Blender, the advantage for me is the simple build with not having to build a mold. I would prefer to vaccuum form the parts, but don't have the resources. I carved the piece from a block of balsa.

Ed mentioned to me about the radio, but need a bunch of 3-pos switches. the grader has a lot of 3-pos levers for the up/dn and sideways motions.

I need to get the wheels sandblasted then powder coated

those are mommoth dump trk wheels

[rc_farmer]

Well, i was able to get the patterns of the moldboard done and sent off to the waterjet. Got'm back yesterday.....and after drilling and tapping all the parts, this is how it looks.

Spent 2 1/2 hrs at the dentist this a.m. and finallyfelt like working on the grade some more tonight. Got the cylinders positioned and now i need to make the swing arms for them.

Are those tires hard to get? Can you hold a rule up to them?

[ihbuilder]

Are those tires hard to get? Can you hold a rule up to them?

Steve they are 6"dia X 2" wide aprox . I have them on my pan , they are for the Tamiya mammoth dump . you can get them from PMD or Tamiya USA till they all run out :eek:

Wow Rob another piece of art :cool: as I expect from a master

IHSteve

[Brian in PA]

Rob, that is incredible! This has got to be a first. I like the jack stand too!:)

Brian

[modelman]

Very nice work! Lot's of small parts. This looks like a hard build but is coming along great!

[td9clyde]

looks great i like this build we need a 140 to grade the haul roads for all the pans now .....so far DP Joe has the smoothest ride lol in a dozer while the rest of use bounce around on these ol pans

[dirtpusher9]

Rob, what are you using for a circle gear? Very nice work.

[JAMMER]

Rob that grader is really taking shape I like it a lot. Talking about radio the F16 can be made to 2.4GHz and have an extra stick also it dual layered Scale Art told me. It has 15 channels plus 6 in 2 layers the price is 689.70 Euro or $940 US. I guess it will even brush your teeth if you want it to. The only problem with it I can see is if you have a problem with it it has to go to Germany to be fixed. Ed :):D:eek:

[rc_farmer]

Rob, what are you using for a circle gear? Very nice work.

Joe, i am going to use a chain, sprocket and geared motor. I made the ring and i plan to have the chain tacked welded to the ring. I have a machinest that will make the retainters for the ring to ride on. Thats the current plan. I would like to use the worm gear method like on the real one, but haven't quit figured out to make that work. It would lok more scale than the idea that in my head at the moment.

Hey Ed, i may have to do like FGD......and mount two radios back-to-back for that kind of dough :D:D I am figuring things out as i go.

That's the best way I could figure to do it too. An intertooth gear is very costly for no more than your getting.What size chain are you going to use? I have some stainless 1/8 '' pitch chain that would allow room for the circle shoes to mount.

[td9clyde]

why not cut your own ring gear and make a smaller one for on the drive motor for it ?

[rc_farmer]

why not cut your own ring gear and make a smaller one for on the drive motor for it ?

Ideally yes, but i don't machine......have ask about getting one made, but too costly.

I am going with this:

http://2wheelhobbies.com/product_info.php?cPath=22_38&products_id=311

I believe this is equievelant to #25 chain

[rc_farmer]

5 spool valve $ 478.00
pump/motor $ 335.00
Airtronics 10 ch $ 429.99 (with nine 3-pos switches) Priceless!

[BigZracingRC]

very good looking build! when do you think it'll be running?

[JAMMER]

Hey Rob when you figure out how to work that 10 channel Airtronics let me know. Ed

[rc_farmer]

Ed, I think the radio might be my one and only Christmas present...:D

I plan to have it completely working by mid-summer '11

I have come to terms that hydro is only way to go. I have tested the air theory and it just will function like i want it too. Air can't be adjusted.

[JAMMER]

Rob good luck with your endeavor. Every time I think everything is going along smoothly something always through a monkey wrench in the mix. Ed:D

[johnboyee]

is this hotrod somewhere in the 1/9 to 1/10 scale?

[Tamiya Cowboy]

is this hotrod somewhere in the 1/9 to 1/10 scale?

I would say it is 1/10 scale in size..

[JAMMER]

Rob your looking good your really coming along slow but sure nice job. Ed:cool:

[rc_farmer]

Thanks Ed, yeah its really slow, but it's starting to pickup a lil bit. Some of my parts where i need strength, i build the prototype out of wood then have them water jetted in aluminum......just spent 20 bucks on 2 can of Cat yellow, but it worth it. gonna start ordeing hydraulic parts after Christmas.

[JAMMER]

Rob I left you a pm. Ed

[Dreamweaver]

Rob, have you thought about using the "Switch 8"

This is quit interesting, making it out of wood is different, wish I could work with wood like that. VERY NICE.

-Mike

[td9clyde]

lookin good i like this build it is something there isn't alot of keep up the great work

[Finster]

Neat project looks great so far. I had an idea about the internal gear ring. What if you cut a circle the outside diameter you want and put some sheet metal or plastic on the edge so it sticks up the thickness of the gear you want. In the middle of this circle fix a large regular gear that gives the ring gear the right spacing and teeth. So basically make a temporary mold and then pour some strong epoxy type stuff it the space.

Hopefully my description makes some sense, if not I could do a quick drawing for ya. Not sure if this is a better idea then your chain idea, but just throwing it out there. I look forward to your updates.

[lorenzo]

Nice project Rob. What dia's should the inner gear ring have?

[ihbuilder]

aw man Rob , your making me look like an amateur :eek: looks great

IHSteve

[Espeefan]

Rob, your work is amazing! Wood, brass, aluminum, whatever material you use, you seem to have no problem getting your parts to be excellent duplicates of the 1:1 machine's parts. Glad to see you are gaining some ground on this build. It's going to be an awesome model when done. Can't wait to see it.

[rc_farmer]

I managed to get a couple of significant pieces done this afternoon. I wanted to us my Robart 2'' stroke cylinders, but needed a clevis to work....so i got on the lathe and bandsaw and WALAA.

Finster, i have solved the internal tooth ring, i am using an r/c motorcycle chain and sprocket for the drive gear. I soldered the chain to the inside of my circle board. It is pretty true for just eyeing it in.

Steve, I am still trying to reach your 'master' status

Lorenzo, I really didn't measure the diameter, I just kinda went from the patterns, i will take a measurement

Dream, I am going to run as much hydraulic as possible. I haven't used a switch 8 before, i just know that i need quite-a-few 3 pos switches so i can center my valves

Robbert very nice you are looking better every day. Ed:cool:

[tc1cat]

After seeing many of your previous builds, you constantly amaze me with what you build. No matter what material you choose, it seems like you master it with no problems. Can't wait to see this monster running around at one of the minitruck meets.
Keep up the GREAT work!!!


Lynn

[rc_farmer]

Thanks guys for all the supporting words. I am beginning to make a little headway on it. I will soon begin work on the interior. It's a fun project to build. I have to figure out things as I go along and the guys at the local Cat dealership have bent over backwards......twice to help me. I am learnign how to use my mini lathe and make some parts. If I had the skills of U expert machiners, I would be further along.:D:D:D

[9W Monighan]

I think you're doing just fine on this build. Did you machine the lift pieces?

REALLY beautiful - it amazes me how it looks like cast iron after the paint ..... just boggling. Interesting comment about the local guys ED - even the business owners that I tend to frequent are helpful ...... at first I thought they would think me kinda nuts and such for 'playing with toys' ...... now I think they're kinda jealous ........ They all work hard for me ..... and others .....

[SonoranWraith]

Looks awesome. You definitely would not know any of it is wood after that paint. Do you do a layer of filler or something to get it that smooth? Have you looked at the Airtronics SD10G? Not sure it is enough channels for you, but all the switches are 3-pos. The F-14 is expandable enough that it would work but with all the decoders it ends being a lot of radio gear.

[woodhog]

for you to have told me in jackson that you work with primitive tools you sure are turnin out a very nice project keep it up:cool:

[rc_farmer]

Lil bit more on the moldboard assembly. Got the braces done and the cylinder bracket made for the blade's pitch. Gotta clean all the solder up. I will sandblast all the metal before i prime it

I am going with the AT SD10G. I just got the nerve to sprang for a pump though, so the radio will be early next yr, after the holiday season.

Sand, sand, sand, then cover with fiberglass cloth and afix with CA. The CA fills 99.9 % of the cloth......sand, sand, filler, sand, sand.....rub ur fingers across it, then sand some more......then prime/paint

[sparkycuda]

The circle and moldboard assembly is looking just great! Nice detail, and really like the novel approach to the circle gear - we often don't recognize a chain works from both sides and doesn't have to be the moving part. I agree with the others, how you make wood look like cast-iron is a wonder. Keep it up!

Ken

[modelman]

rcfarmer-your doing really great work! That model looks very complicated to me but looks like you have it well under control. Nice job!

[Espeefan]

This, your work, is insane, Rob! I cannot believe the painted parts for the blade lift are wood. This is going to be an incredible model, when done. I cannot wait to see what developes.

It doesn't seem like it's turning very sharp or is it?

[9W Monighan]

It doesn't seem like it's turning very sharp or is it?

Graders don't turn very sharp but when he leans the wheels it will turn sharper.

Coming along nicely.
What motor rpm,pump pressure and gpm is your pump operating at?

[rc_farmer]

Graders don't turn very sharp but when he leans the wheels it will turn sharper.

Coming along nicely.
What motor rpm,pump pressure and gpm is your pump operating at?

When the wheels are on, you will be able to see the difference in the turning. I am going to use the Leimbach pump. Its only 10 bar. I may have to upgrade to a bigger pump later, but for now, i think this will work. Had to test it......couldn't wait for pump to get hear.....:D:D:D, Hopefully it will be here by first of the yr.

[td9clyde]

i am really liking this build i always liked running the 140's alot better than the 120 this is going to be one cool build

[RCLogger]

WOW very nice Rob ! ! ! You should give me a lesson on soldering, you have it mastered.

How many spools are you going to have in the grader ( functions )

greg

[Lil Giants]

I guess I need to pay more attention when I see the municpal grader turn around, I thought they turned quite sharp without leaning the tires. :confused:

I wonder if the Mammoth tires will roll on edge, sidewalls might be too soft. Perhaps stuffing the tires with plastic BB's will stiifen up the sidewalls without adding too much weight.


What makes the difference in hyd flow is the size of hyd hose and fittings. What size do you currently have on your Gator Rob? 1.5mm ID?

My current excav & wheel loader are using 2.5mm with the 350ml/min pump and cycle speed is significantly quicker, I would say more than double, than the older models with same pump & 1.5mm hose/fittings.

[rc_farmer]

Td9-I have never run any of this equipment before. I just like building different models.....I am building this one from pictures only. So far, I have probably taken about 200 pictures to build each pices.


Greg-6 spools when completely done. After building the Gator, the soldering is a breeze now :D, don't mind sharing any tips that might help ya:)
Patience is always the third hand....

I do have the 1.5mm ID. Getting all this hydraulic stuff right is the challenging part for me. I appreciate the info of the 2.5mm, which is what i think i need for the grader. I ordered the biggest tank from Leimbach. Good idea on the plastic bb, was going to add some to the rear as well.

amazing work

[Tamiya Cowboy]

Robbert that is truly outstanding craftsmanship.. I know you said the picks would be worth the wait on the phone and you were more than right.. Keep up the great work..

[mazdaparts]

The grille and fan look to be a very good printing. The paint and detail are amazing. Its hard to believe this is wood.

[rc_farmer]

Thanks guys for all the kind words...... they help me stay focused at times. It's been a long build but its finally coming together. I am working on the interior while i wait for the pump/valves to get here.

Thanks again!

[Dreamweaver]

Rob, truly fine craftsmanship. My first though when I looked at the first pic, looking at the back of the motor was how the heck did he make that fan look so real. It wasn't till I looked at the lights that I realized it was a print of a real one. I know how small of an LED you can get and they come small but not small enough to put that many of them in that size space..

-Mike

[tc1cat]

Isn't that kind of cheating to use a pic of the grill instead of making the grill and fan:rolleyes::rolleyes::rolleyes: It does look very real! With most of this build being wood, it is still unbelievable the way you make it look like metal.

Lynn

[Espeefan]

Wow. The painted parts look just like die-cast metal or something similar! I know it's wood, but seriously, no one would know the difference, unless you told them, or they felt the model with their own hands. Super clean paint job.

[hawgfanman]

Awesome!!! Can't wait for more updates!

[td9clyde]

update update update pics please!!!!!!!!!!!!!!!!!!!!!!!!!! can't wait to see this thing all together and moving

[dirtpusher9]

WOW Rob, that is outstanding work. I don't know why I'm surprised with the quality work you do. Can't wait to see it blading a pass. If you need an operator, let me know.

[RCLogger]

Great work Rob !
Can't wait to see it moving dirt, it will be alot of fun moving dirt. We could sure use it up North for finishing up all the dirt roads we build.

greg

[rc_farmer]

Thanks guys. In the past two wks, I have had two toy show, so progress has been a lil slow, plus I am still awaiting the pump and stuff. I am workign on the interior while i wait.

DirtP9: I will probably need a block of instructions on how to run this thing after i get it all together.:D

Greg, I will get it on a flatbed to ya...lol

[hottrod1022]

nice build

[RCTech9]

We need a update.

[Izzy]

as is ussual - Very Nice Rob.......still can't believe how you get such a nice look - it really looks like castings...... - must be in the flowing raius and fillets......

really looking forward to seeing this run about......how long is it anyway??

[sparkycuda]

Grader really looking good. Still can't believe that so much is wood, but doesn't look like it. I'm not coordinated enough to run a real grader, so I am waiting to see you operate this rig! Keep up the great work!

Ken

[rc_farmer]

I should have some more updates by next wk's end.

[rc_farmer]

I made the protection brackets, the bottom plate and tow hitch. I didn't want to have all that open space in the rear. I am going to make somewhat of a motor to look the part.

[Lil Giants]

Remarkable craftsmanship Robert, no one would ever guess it's made from wood. Keep the pics coming. :cool:

[Trucker47]

wow looks great! just like lil Giants said no one would ever be able to tell its wood :D

Chris

[lorenzo]

Wow, that's good :). How did you worked the surface that the paint looks so smooth? Did you fill the tyres or are they just hollow?

[9W Monighan]

You would make one heck of a pattern maker with the way you can make that wood do what you want!

[tc1cat]

Pattern maker-HA- more like a pro model maker, museum quality models that is!!:eek: I do believe this tops your ag-sprayer and cotton bail truck.

Lynn

[rc_farmer]

Thanks all for the kind words, but "pro", no not me, i just have a habit of trying to pay attention to the details. Patience goes a long ways in this hobby.

tc1cat- when iset out to build a model, i look for something to challenge me

9W- thats how i got suckered into building two Globe Theatre's for Romeo and Juliet set while in High Sch.....it was fun to do

Lorenzo-To get the paint to look smooth, i cover the wood with glass cloth, then sand, fill, sand to the touch

Lil Giants and Trucker47, those words mean alot coming from your guys!

Thanks again:D

[td9clyde]

very nice work i really like the details and the way it turns out when the part is made

[RAIDERS]

WOW ROB great work...

[ihbuilder]

Rob , I said it before and I'll say it again you are a master :eek: attn. to detail = master ;)

IHSteve

[rc_farmer]

I was wondering how the wood would take the strain of grading when the model went to work, now with the class cloth to add to its strength it should do well, I look forward to seeing it do its first cut.
Did you use fine weave or a silk when covering? & did you use glass reason or an instant glue to bond it on with?
A truly remarkable bit of wood work, well done
Tim

Tim, i used fine-weave cloth and CA. I also used gap-filler CA. There is also a lite-filler called balsa Rite. I use that after the first or second sanding to get low places or maybe where i sanded thru the cloth.

[rc_farmer]

Rob , I said it before and I'll say it again you are a master :eek: attn. to detail = master ;)

IHSteve

Thnxs Steve, coming from a true craftsman.

[Hemi1966]

I have to agree with everyone, you truly are amazing graftsman:D
Wish I could get even half of those details on my 14M:o

[Izzy]

That power unit is stunning...... Looks great!!!

[Espeefan]

I agree! Totally insane level of detail here, Rob. Incredible work. I don't care what you call yourself, but I think you are more then worthy of the term 'pro'. Good work.

[Stuff]

Wow. just wow! keep the steam going!

[Tamiya Cowboy]

You were not joking when you said you had been pulling lots of line yesterday.. Looks great Robbert nice work.. Oh and I got my project working too..

[tc1cat]

Can't wait to see it in person! Has to be your best build to date!!

[9W Monighan]

Going nutty with the hydos eh?:eek: That will be a grader I'll have to see someday !
I just moved the frame of my 1930 Caterpillar Motor Patrol grader into the shop yesterday. I want to get it ready to be sand blasted so I can start the restoration.

[eef7260]

This is gone be a great model.
Really like the high level of detail.
I am very comfortable with metal but with wood never in a 100 years i could do what you are doing.
Hard to believe there is wood under there , never thought you could finish that so smooth.
Keep us updated on this super project and thanks for the pics so far.

[rc_farmer]

that will be a good restoration project. I have loved mechanics all my life and the way intricate parts work together. It might take me a lil longer to build a model like this, but i try to make function as close to the real machine as possible.

[russisloud]

your grader is really coming along. looking good too

[Tamiya Cowboy]

Holy crap :eek: Robbert you are really hitting the details nice work..

[ihbuilder]

" you are not a "pro" :rolleyes::rolleyes: "


nope :rolleyes::rolleyes: just 1 of the best masters of his craft I've seen :eek::eek::eek:


Looks REAL good Rob

[dirtpusher9]

Rob, you're moving right along and man it looks good. What is the ETA on this build? I can't wait anymore. We have to get together again, soon.

[rc_farmer]

Hey Joe, its good to hear from ya. I am working on the cab and interior....today, I painted the inside with the sand tone, tomorrow I will prime and paint the outside. I made the windows and got them on the dorrs today. If the weather holds as far as temp. and low humidity, this should all be done by the wknd.

[JensR]

This looks really wonderful!
The care you took in the appearance of the circle gearbox and the lattice(?) work on the back of the moldboard-carrier - sweet!

How strong is the circle rotation?

[rc_farmer]

90% complete....I still have several pieces to make and add some lights. Finish detailing the cab interior, add details to the control column and make arms rest for the seat.

All I can say is you built a "MASTERPIECE". I just gasp in aaahhh:D
I can't add anything that hasn't been said, you're da man:)

Big John

[Tamiya Cowboy]

Holy Crap!...WOW It is a true master piece..

[JAMMER]

Rob you have done a spectacular job on that grader. I like the way all the functions work, you have done tour self proud. Ed

[tc1cat]

Rob, You have truely outdone yourself this time!:eek: Except for the wood beams in the engine compartment, there is no way a persone would or could know that it is made from wood. This tops your sprayer and your cotton bale truck combined!! :D Now I just need to see it in person!

[steamer]

Truly a museum masterpiece. But you've taken the next step and made it operate as well. What have you got on your plate to top this one.
Rob

[JensR]

Wonderful :)
Had seen the video before (or one like it?) but not the details of the cab.
IMO that level of detail just puts this over the top (in a good way)!

[egronvold]

Awesome :D

It's very good looking, and it seems to operate very well.

[sparkycuda]

:) What a great model - looks, operation, detail - all just awesome. I'd never believe it started life as a tree! Wood is such an unexpected medium for a working machine, but when done so well, who'd a thunk it!

Kudos for such a wonderful project!

Ken

[Snochaser]

Awesome job. Smooth as silk. I looked at both videos, guess there is a little tweaking to do?? It'll be nice to see it in some loose dirt; watch it roll up a nice windrow.

Ben

[rc_farmer]

Thanks guys for the kind words. Yes,i have a little tweeking to do and learn how to drive it :D. I only have one switch that is spring-loaded. It would be nice if all the controls were, but I am happy that i have gotten this far. I may get a chance this wknd to put it in some loose dirt and see what happens.

Again, thanks all!

[JensR]

Learning to drive is difficult, but soooo much fun :D

As you saw, I modified my transmitters' controls for my grader, maybe you could do something similar (it's really not difficult).

But what do you mean with "switch" - aren't you operating most of the functions with proportional sticks?

Cheers
Jens

[Izzy]

Bravo! Fabulous work - turned out awesome as usual.

[rc_farmer]

Jens, I am using an Airtronics 10G.....U can assign the functions to any channel that suites your desire. Here is how I have mine cnfigured:

Elev stic=circleboard rotation
Aile stic=Steering
Rud stic=Pump
Thr stic=Throttle

8 different (3 pos switches) that are mixed with the rudder channel to control the pump. The pump only operates when I move a selected function.
Of those 8, only one is spring-loaded....the others are on-stop-on

Learning to drive is difficult, but soooo much fun :D

[rc_farmer]

Thanks Iz,

Bravo! Fabulous work - turned out awesome as usual.

[JensR]

Ah, okay, I understand now: No proportional control on those channels.
I guess you could solder in different switches, but the Airtronics is a bit too expensive to just try it...

[modelman]

rc farmer-I really like the way this model turned out and the detail work is just incredible. I enjoyed the videos also. I have a question for you or anyone who can answer it. What is the advantage of leaning over the front tires while scraping? I have watched scrapers work and doing this but I never knew why.

[9W Monighan]

The wheels lean to counter act the blade pushing the front tires sideways,"Lean into the work" It also makes it easier to turn tighter.

[doodlebug]

Wheel lean helps counter act side draft or force from the moldboard.
Lean the wheels toward the heel or lagging end in most grading.
Look around and you will see people who are clueless on a grader.
Think of it as digging in your heel to fight the tug of war, dragging your toes doesn't work
As well. Later, Neil#2 aka doodlebug.
Hey 9w, I can't type as fast on the phone lol!

[SmallHaul]

Incredible machine! VERY nice work.

It very realistically simulates the full scale machine in both form and function. It will be a treat to see it push dirt.

[JensR]

When I presented my grader model at a recent show here in England, the most common question was "Do the wheels lean?" :D And I said "Yup!" =)
So, obviously people notice it as something characteristic - and I was glad that I had decided to realise this function on the model.

[rc_farmer]

Almost done...

[ddc333]

excellent top notch finish

what did the CAT dealer have to say

[rc_farmer]

The Cat Personnel have been very supportive. The want to put a write-up in the compnay news letter. I am also planning a trip to the 14M factory down in Little Rock, which is about 2 hrs from me. I think that will be exciting.

It's time to start the testing phase. I noticed the discussion about the blade and the circle board being able to hold. Mine will have to cut loose dirt....as i used the same setup on the worm gear.....only difference is my box is made of wood. When i find me another machinest, i will get the gearbox made correctly.

[heavy_duty]

Robert,
All is can say is,INCREDIBLE,you have pulled another rabbit out of the hat.
AWESOME.

Chris

[tc1cat]

Rob,
This has got to be your best and most impressive build to date:eek: You need to get some pics of it next to the real thing. Please let us know what the people at the Cat factory think of it.

OH ya, PLEASE don't break it before Indy!! I really want to see it run!

[dirtpusher9]

Rob, YOU KILLED THIS THING Man that is nice, can't wait to see it.

[rc_farmer]

Thanks Joe,
I take notes form the best. I have been doing some field-testing before I finally release it. Tweeking a couple of things to make it a lil more durable.

[hammer]

That is one sick looking machine very impressive can't wait to see the finished product.

[cbazq271]

What do you cover the wood with?, Bondo, gel-coat?

[rc_farmer]

Sneaky-pete, thanks for the complments

Jammer, I appreciate the helpful information on parts to make this model possible.

Hammer, I should be putting the step ladder on today and she will be finished......WHEW!!!!:D

Cbazq271, To prep it, i used a balsa filler called Hobby-Lite. The filler is easy to use and contours very well. That sealed all the cracks and holes. I used a wood sealer/primer for base coat, then the Cat yellow........oh i almost forgot, 1st thing was to sand, sand,sand, sand up to and including the primer. :D

[mazdaparts]

WOW I too thought the first few pics were of the 1:1 for comparison sake. You nailed it. Great Job.

[steamer]

Rob, Your grader build is awesome and knowing how it was built is amazing. Great work from a very skilled builder. We need one more picture though, you standing proudly beside it so we can see how big the model actually is.
Rob

[tc1cat]

Another outstanding build from an outstanding builder:D:D Unless someone knows, you would never guess there is wood under some of that paint.

[Car5858]

Love that grader, top shelf work if ya ask me.

Nice job :cool::cool:

[JensR]

And I mean "great" - not "great considering it's wood" :)

I'd love a play area like this close by #sigh#

[Trucker Al]

[modelman]

rc farmer-the model looks great and all systems seem to work flawlessly! Sit down and have a cold one. You deserve it!!

[rc_farmer]

Thanks EVERYONE for the kind words! There are 6 things I want to change on it........the WHEELS, these are bad for traction and steering, overall, I am satisified.

Here is a size comparison:

Build material: Wood
Build time: Approximately 1 year
Length: 43"
Width: (outside of tire-to-tire) 13"
Height (ground to top of Cab) 15"

The final result is outstanding that first photo looks so real I had to check it was a model

I had a quick look back but couldn't see any reference what was the final scale ??

[steamer]

Rob. Thanks for the great photo. My complements again for such a great build. Anything on the burner yet for your next build.

[Brian in PA]

Rob, that is phenomenal!! I haven't viewed the thread for a while and I am astounded!! This is a great piece of work.

Brian

[Pippoe]

The grader looks fantastic and runs just as great.

..and a great presentation too. It can easily be mistaken for a real one!

WELL DONE!!

Cheers

Pip

..and I admire your perseverance.. I started my truck years ago and it still isnt' done.. and it's an easy project compared to yours.

[JensR]

Great to see you, Rob :)

As you mentioned the tires, maybe going a bit smaller with these?
http://store.rc4wd.com/Rock-Crusher-XT-22-Tires_p_730.html
Those are the popular 2.2" wheel size.

Next size up is Series 40 - with tire diameters of 200mm or more - so these would be too large.

Apart from that, maybe the traction could be improved a bit with more weight? I guess your wood construction is fairly lightweight?
If so, some people put lead or steel into the tires. I am a bit scared of lead's toxicity, so would look at different solutions first

Cheers
Jens

[Espeefan]

Incredible work, Rob. I hadn't checked this thread for a while, and all of the sudden, when I do, the grader is done! Imagine that! It's a great looking machine. Like the others said, almost impossible to judge the difference in the photos, if it is a model or the real 1:1 machine. There is only one thing I could possibly suggest. It needs a full set of working lights and maybe a couple other little finishing detail touches. Grab handles, windshield wipers, ect. I'll bet you have that in the works already, knowing your attention to detail. It'd be really neat if you decided to go all out and turn it into a snow fighting machine too. V-plow and all.

Hey Nat, I do plan to put some lights on it and I do have an idea for GPS gear on it too. I am having some rippers being made now for it. All of these items were planned as accessories. The windshiled wipers and grab handles are already attached in the major places. The doors have handles also and all the hydraulic levers move as well as the column is adjustable. The seat swivals for ease of exit....:D

Apart from that, maybe the traction could be improved a bit with more weight? I guess your wood construction is fairly lightweight?
If so, some people put lead or steel into the tires. I am a bit scared of lead's toxicity, so would look at different solutions first

Cheers

Contrare to belief about the weight, it is quite heavy, I estimate about 30 lbs at least. I have plastic BB's in the rear tires. I had them in the front, but turning was harder.....it just pushed the frontend. The other issue is the surface area of the tires. They are very flat and covers the entire foot print on the ground. There needs to be some hump in the tire. I will experiment with additional weight attached to the front.

Guys and Gals, I can't say thank you enough for the kind words. I don't know what my next major endeavour may be as of yet.

Again thanks everyone.

[JensR]

Ah, good with the extra weight!

Yes, the tires are not known to be great performers...

I couldn't resist a bit of numbercrunching.

From

http://www.ritchiespecs.com/specification?type=Construction+Equipment&category=Motor+Grader&make=Caterpillar&model=140H&modelid=91709

I get the scale as:
width 2464/(13*25.4)=7.5
length 8713/(43*25.4)=8
height 3131/(15*25.4)=8.2

So, let's go with 1:8.

Then the rule of thumb for the weight would mean we should be looking at a weight of very roughly (models tend to be lighter almost always) 14677kg/8^3=29kg :eek: which would be about 65lbs!

Cheers
Jens

:):):) Really a great model. Details and finish are awesome and it functions extremely well. I like the cab interior detailing the best because it is something that does not always get finished and you really hit it - including the color. Closeup pictures match the sales brochures!

Congratulations on a fine build!

[BOBCAT]

Im lost for words.this is an awesome build and you are a true master craftsman.

[pigeonfarmboy]

Got to put my grubby mitts on the controls of this puppy today!! What an awesome huge custom build! Thanks for letting me attempt to operate the beast Robert.

[Straywolf]

Man i was just blown away with this. Great work!!!!!

[mazdaparts]

I got to see the grader in action on saturday and the pics and video do not do this justice. It is HUGE and very realistic. It performed very well. Great to finally meet you and a little birdy told me today is you birthday. HAPPY BIRTHDAY ROB!!!!!

[rc_farmer]

Thank you for the Happy BD wish Madza

We had a great time and it was a pleasure to meet each of you and put a face to a name.

[calm n sedated]

Rob, I've been gone wayyyyyy! too long!!! you never stop amazing me:eek: Great job again.

[fhhhstix]

Fantastic model Rob and thanks for the opportunity to take it for a spin it definitely works as good as it looks.

Rob, I've been gone wayyyyyy! too long!!! you never stop amazing me:eek: Great job again.

Hey Greg, glad to see you made it over!

Thanks!

[Iron Art]

Rob, Great build, you've set the bar pretty high, Thanks for sharing. Fred

[dirtpusher9]

Rob, I had thought long and hard about buillding the 140, but now seeing this, I'm glad you built it. I look at these pics every time I get on here. Once again well done!!! Wished I could have made it to the show and seen it in person.

[rc_farmer]

Joe, i remember you talking to me about that some time ago......i was looking forward to you building one too. Your work is truly an amazing piece of craftmanship. I was hope we could push some dirt together last wknd. :D

[td9clyde]

your grader is an awsome work of art it is very amaizing with the materials you used and it all looks like metal keep up the awsome work

[td9clyde]

Like wise it was my pleasure to meet you i had alot of fun ...i guess i see things in my model that i shoulda done better with but it was hard at the time for the lack of tools and a tape measure lol when i shoulda been a lil more picky ..... and on the the other hand Your grader is very awsome I kid you not guys and gals this grader is smooth and quiet very cool to run and i also thank you for the oppertunity to run your grader

[Snochaser]

Rob your grader was a treat to run. So smooth and amazing complexity.

Ben

[Iron Art]

Rob, Good to see you and your grader in Toy Trucking & Construction Magazine. Great job! Congrats!! Fred

[Stefan]

Rob, your model is really great and I envy you already being able to run it after such a short completion time.

[rc_farmer]

Since Indy, I have been asked to post some video of my grader, so here is a lil sinppet of it doing some dirt work....enjoy:D

http://www.youtube.com/watch?feature=player_detailpage&v=ldAlbO33oRQ

[Supermario]

Thanks for the videos Rob :) looks and sounds great! It was nice to see it pushing pellets at the Indy show but looks way more at home in the dirt :cool:

So if it's completed......what's next ?:D

Mario

[dirtpusher9]

I like the video Rob. Would like to see it and you in St Louis next month.

[dabears]

I love that grader! Awesome work

[Daddy Mack]

Great looking grader there mate...

Well I revisited this thread today, and actually read the posts instead of a quick flick through lookin at the pics...
Your craftsmanship is brilliant... To get a glimps of how you created the model without the use of lathes and mills, is extraordinary...

I've been in the dirt game for around 20 years, with alot of that spent on graders... I've always wanted to build one, but just couldn't see how to even start it... So to see what you have done using photos and brochures is simply awsome...

Very inspiring... Now I guess I need stop making excuses... And have a crack at it...

Again... Brilliant work...

...Luke...

[dirtpusher9]

Rob, it was a pleasure running your blade at the show and I thank you for it. I sure wanted to get a couple pics of it and my dozer together and forgot all about it. For those of you that have not seen this 140 in person, pics do not do it justice.

[Southgate]

I am just discovering this project. I first opened to the last page and saw the finished product. I thought it was all metal. My wife asked if it was a scratchbuilt model. I went back and am so impressed with the combination of materials. Wood, brass and aluminum look so beautiful together before paint, and even better after. This is art! Dan

Joe, U seemed right at home driving my grader. I deem it an honor to get such praising words from U and all the other fellows. I have no time or experience on the 1:1., I just studied the machine and took many pictures in hopes of getting it close to the real thing as possible.

I managed to get a couple of pics of ours together.

Rob, it was great to see this in person job well done ;) only thing , there's 1 cat missing in that pic :p:p:p

[rc_farmer]

I think we all inspire eachother to build something that we may have thought was too difficult or too long of a building process.

Bring that big monster on Steve and add it to the fleet!:D

Hey rob I just reread your thread again from start to finish ..I dusted off an old project i had started a few years ago and started making parts again ..wth the little cnc knowledge if have now it is making things a bit more precise and a little easyer ..many hours in front of the cad program ..I can see what of challenge this thing was Rob ..this build is amazing and one of my top favorites of all time along With Ari s ..I know mine wont turn out half as nice as your ..anyway I want to ask a few questions ..about the Blade lift cycler arms and center mounting bracket and pin ..I there a geometry that when pulling that center pin and moving the whole assenbly off center and using another adjustment hole ..This is for moving the table way over and angleing for side angle gradeing ..Did yours match up ? I couldnt find much info of that and am drawing it as close as I can ..I am also wondering how well that little gear motor worked for the circle gear ..I plan on using one as well ..what rpm are you using ? thanks ..And Well done rob

Hey Lou, i know you will do a fine job on your grader. There is a lil geometry to that center pin....what i did....i made a rough bar and measured the holes at different intervals by swing the the moldboard back and forth, then i came back and drilled each hole, then made the actual bar. It lined up pretty good after putting everything back together. This was all freehand....i didn't draw anyhting up on the puter....so it was pretty much all eyeballed and pencil.

This lil gear motor, i believe is a 35:1, i got from robotmarketplace

[rc_farmer]

The blade lift cylinders....i had those made by this guy ib canada...http://www.up-1.com/products.html I sent him my drawing and he made them. I order them w/o the nipples so i could slide the sleeves over them, then i soldered the nipples on the cylinder.

He is a really nice guy to work with.

[tracksntreadslou]

Hey thanks Rob ..I took most of your advice .I did machine out the center hole and two outer to hold things true .then hand drilled the remaining holes ..It turned out pretty close but the far outside hole didnt work out very close so i may draw it out again and modify it later ..Quite a bit of geometry to that peice ..The whole mold table in fact..Hey thanks for that link ..I do have a few cycliners that will work kicking around and will use them for now ..Thanks again
