CAT 14M Motor Grader

[Hemi1966]

Hi guys,
I finally got time to start thread of my current project, CAT 14M motor grader. It´s going to be in 1:14 scale and build mostly of aluminium.
Here is the original:

very nice

[aseejr]

WOW again!!!

[mog]

wow love your work. i tell right now this is top noch and i don't think anything can come close to it. you are a ture craftsman. thanks for shareing.

[Hemi1966]

Thank you for all the compliments:o. There are plenty of great builders in this forum that I admire:)

Today I made housing for the hydr. pump and the motor. As you can see I use tooth belt between the pump and the motor.
The pump is from Jung-Fluid.

Hi Dan,
I´m more than happy with the Optimum. I have the BF20L that I converted to CNC, it´s amazing machine:)

[steamer]

Ari. That's one fantastic Cat. Are you a machinist by trade. Keep the pictures coming.
Rob

[pugs]

Very nice looking work and cool build!

[RCTech9]

That is just BEAUTIFUL!!! You have some of the best skills on the forum!!!

[Mustang]

Great looking build, fantastic workmanship!

[tracksntreadslou]

WOW ..Nice build..Like the choice of tires you picked as well...Where did you find those?...Cheers and welcome to the forum. Lou

[rc_farmer]

I have got to give you PROPS on your build. Great machine work.

[Hemi1966]

Are you a machinist by trade.
Rob

Rob,
I am a machinist, but in the engine rebuilding section.

Lou,
those tires are from German company called AFV-Model http://www.afv-model.com/4711shop/product_info.php?info=p2663_Michelin-26-5R25-XHA-scale-1-14-5.html

[sparkycuda]

Great detail and workmanship. Would like to see the your CNC setup. Would you post a picture of the machine running one of the next parts for your grader?

Thanks.

Ken

[9W Monighan]

Yes indeed this is a very nice build. I have a soft spot for road graders. I own 4 antique Caterpillar graders built in the 1930's.

[mazdaparts]

You have a lot of skill. All I can say is wow. I am among very talented craftsman on this forum.

[TheMachinist]

Wow this is an absolutely beautiful build. I can't wait to see more photos.:cool:

[doodlebug]

Saw these on Big Lorry Blog yesterday, somewhere in Australia.
Enjoy, Neil#2 aka doodlebug.

[chaseracer]

beautiful work, this is some fine craftsmanship, the finished result will be exciting to see.

[Deereman]

Wow this thing is amazing. Keep up the great work.

[Snochaser]

Awesome! You guys are killing me with your CNC machines. Great work.

[Lil Giants]

At a loss for words... :cool:

I've been dreaming of one of these in 14th scale for yrs!

I hope you are saving all your G code to make more than one? :D

How much time has past to get to this point in the build?

What rpm gear motors on the rear drives?

[td9clyde]

yea your grader is very awsome i like it alot keep up the awsome work

[Izzy]

Ari - welcome --- where have you been hiding??;)

Your machining skills are great....I like the front axel set up... And the multi point backers are sweet.....


Are you scaling this all from photos and measurements? Or are you engineering and using the 1:1 for inspiration---- either way it's up there with a few of the the greats........

All G-codes are saved, but I might do many parts differently if I ever build another one.

I haven´t kept any records of how much time have I use, but I would estimate something about 300 to 400 hours:confused:

The motors are RB 35 with 1:100 gear boxes.

For measurments I´m using Norscot 1:50 14M diecast model witch I hope is accurate enought, and also I have some 14M brochures witch have some measurments. I also have many photos of it.
Sadly I havent been able to take any photos of it myself.
I wish have one in my yard witch I could take measurments and maybe do some road work also...;):)

[elliot330]

Hi Ari... fantastic opening post and I knew your machining skills would be appreciated here... keep the photos coming...

[RCLogger]

Great work Ari
thanks alot for showing us your skills, I am impressed with the work you have done. Keep the photo's coming.
How many spools are you planning on useing, there sure could be alot of functions if you went with all the grader has..

greg

[Espeefan]

Wow. I'm at a loss for words! I wish I had half the talent you do in your little pink alone! Your machine work looks incredible! The front axle is a work of art. Amazing. This will be one build to keep an eye on for sure. 5 star thread!

[hawgfanman]

I think everyone has pretty much summed up my feelings with WOW! Absolutely awesome!!!

[modelman]

All I can say is-I agree with everyone-amazing work!

[Hemi1966]

Today I made the housing that covers the frame in front of the cab.
Here is some pictures of making it:):

[tc1cat]

There are no words left to describe this build. Making your own body shells like photo-etched brass is completely over the top.

Lynn

[cjwrctrucker]

Words cant describe this build. Incredible!

[Bigrigger]

Awesome work! You are a great builder!!!:D

[woodhog]

grader looks perfect how do you find time to build so fast:eek:

[SonoranWraith]

grader looks perfect how do you find time to build so fast:eek:

Its not fast he just caught us up to current progress. He mentioned in earlier post that there are 300-400 hours in it so far.:eek:

[Lil Giants]

Nifty seeing how you planned the cut so it bent into the right shape... did ya do it on the 1st try? :D

I never could draw or inivision in 3D before, likely the reason why I get frustrated with scratchbuilding. You however are doing a fantastic job! :cool:

What's its current weight?

What's its current weight?

First I made the part out of cardboard, bend it and try fit it to it´s place. Then I took the measurments of that, and made the program for the milling machine.
And it was not successful on the first time:(, I actually made a new one today, the one I show you earlier was too wide.

Weight of the grader so far is 5,5 kg

[Hemi1966]

Today I made the roof side sections, witch where difficult to make.
What makes them hard to make is that the other side is straight, and the other is curvy like an airfoil. To be honest I´m not totally satisfied how they turn out:mad:, but maybe some bondo and paint will do the trick;)

Hey Hemi1966, do you need any detail shot's taken, will be at the Cat booth next week?
Let me know.
Later, Neil#2 aka doodlebug.

I would be grateful to have all the detail shots you are able to take:)

Thanks in advance

[elliot330]

Looking good.. quick question, what is bondo?

[9W Monighan]

I don't think it looks too bad. Don't be so hard on yourself.
Elliot, Bondo is a cheap 2part autobody filler that can be sanded once it has hardened.

[td9clyde]

looks great i can't wait to see this thing workin

[rc_farmer]

Hemi, you are not half-stepping by any means on this fantastic build. I commend you on your skills.......i can't wait to see "yours" working!!! Are you going to use hydro on the cylinders?

Keep up the great work!

[Hemi1966]

Are you going to use hydro on the cylinders?


Yep, thats the plan. Not sure how I´m going to get everything reasonably organized to my radio:confused:

[Lil Giants]

How many ch radio & what kind do you intend to use?

Are you going to self make your own hyd system too?

[tracksntreadslou]

Great metal work Ari...That looks as though its a very difficult shape to model..
It seems that most of the new equipment built now has a number of different shapes that make it difficult for the modeler to aquire.. Not like equip made in the 70s 80s ,90s with most panels flat and square.. Cheers lou

[johnboyee]

Yes, just amazing, awesome work! Tell me what ever shots you needs upclose, I'll just climb off mine and take them! Are you goin to have a way to run just one set of rear wheels, kinda like a diff lock? if it's like the real thing, it's gonna push real bad when u try to turn!

[Heavy Metal]

Don't know what to say...the boys have already said it all. Fantastic work!!! I am inspired! Joe

[Hemi1966]

Hi guys,
I got time to continue with the grader, and I made one of the side covers for the engine compartment.

http://i327.photobucket.com/albums/k471/Hemi1966/IMG_3248.jpg

http://i327.photobucket.com/albums/k471/Hemi1966/IMG_3250.jpg

[rockNmayhem]

Wow that cab is looking amazing and I like the engine side cover. The added handle looks great as well. So are you gonna have a working door on it so you can access the inside like you did on the cab?

[SonoranWraith]

I just about pee myself when I see an update to this thread. :D:eek:

[Jared]

My chin is getting bruised up bad from my jaw dropping every time I see an update. :eek:

[TheMachinist]

Absolutely beautiful!
I love the smell of fresh cut aluminium in the morning:)

I can't wait to see the blade frame and turntable hanging off it.

[Hemi1966]

Today I made the right hand side of the engine cover. Again this is a good example of these modern machines, round shapes equals good rear visibility, but quite difficult to make :mad:

[9W Monighan]

Very nice milling. What program are you using? I maybe in the market for a new one. I've been using Bobcad 19 for some time with my old Bridgeport with a ProtoTrak MX3 control. I got V22 but never used it because v19 was easier for me. Last week my old computer took a dive and now with windows 7 I'm having problems. The biggest one is it prints completely black pages. I had that problem with v2007 and v22 but never could fix it. Sorry to change the subject.

[Azorean]

WOW... that´s amazing.

keep the great job.

[Hemi1966]

Very nice milling. What program are you using?

I´m using program called Pcdreh (Pcturn). It´s a CAD/CAM software, and very simple to use.

Here is couple of pictures of the engine cover, I manage to make the front and rear pieces:)

[Hemi1966]

very nice work how long is it?

It´s just under 27 inch long.

[td9clyde]

That grader is a masterpeice i really like it seeing alot of the builds in aluminum makes me want to try aluminum but the stuff is so hard for me to work i think i will stick with my metal .......how wide is the molboard? and the width ,and weight i have been watching this build it just amaizes me keep up the awsome work

[Hemi1966]

Today I made one of the side ventilation hatches, and the lower back piece.

[tc1cat]

What a build!!:eek::eek: Just keeps getting better with each update. Truely amazing what you can do with CNC equipment and a good Cad/Cam system. I do have a question for you: With all of the detail you are putting in this vehicle, why did you only put less than 1/2 of the number of bolts in the drive line compared to the pics you show of the real thing? I realize that it won't be seen very easily but looks like it wouldn't have been much harder to make completely prototypical???????

[rc_farmer]

The machine is only as smart as the programmer......Top-notch work :D:D

[9W Monighan]

You sure are good at programming your parts. Very ingenious way of simulating your door panels. I've seen this done on lazer cut sheets and the designer burned shallow lines for the press brake operator to know where to make his bends.

[Hemi1966]

Today I made the front bracket for the articulation cylinders :)

http://i327.photobucket.com/albums/k471/Hemi1966/IMG_3297.jpg

http://i327.photobucket.com/albums/k471/Hemi1966/IMG_3298.jpg

[rockNmayhem]

Ari it is looking great and seems to be coming along nicely. I like the way you made the vent panels but one question I have is how are you going to keep them mounted to the side pannels? I don't see any mounting holes in them.

[Espeefan]

I stand in awe at your talent. What more can I say? This model is right up there with the best of the best I have seen on the forum. Incredible. If only I had a fraction of your talent to build something even 1/4 as good! Yikes!

[Hemi1966]

This weekend I started to make the blade circle:)

Wow. Incredible!

[rc_farmer]

Outstanding craftmanship!! Can't wait to see it action.

[TheMachinist]

Wow it's really starting to take shape:cool:
What grade of aluminium are you using? The endmill is leaving an awfully nice finish without any coolant or cutting oil.

[pugs]

Looking great.
I see some pics with what looks like prints. Are you designing these complete before starting or just using a parts manual from the 1:1 to go by?

[tootall]

That is is one nice looking machine.

[9W Monighan]

Nice circle. How long does it take to mill those 6 brackets out?

[Hemi1966]

Wow it's really starting to take shape:cool:

I´m using AlCuMgPb (3.1645) grade aluminium.

48 min. + tool changes:)

Those prints are from Cat 14M Operation & Maintenance Manual that you can find on there home site. There are many useful detailed drawings of places you dont see on the photos.

[RCLogger]

Ari It is not very often I don't have anything to say, BUT everytime I check out your build I can't speak because I am drooooling to much. WOW
Very nice

greg

[dirtpusher9]

WOW, the competition has really ramped up since I build my dozer and pan. I must say you are doing it right, hiding the fasteners as much as possible and all the detail you are putting in this, makes it a much more realistic looking model. Outstanding work!!!!!!

How did you make your circle gear and how are you planning on powering it?

[JensR]

Some unbelievable workmanship there.
The way you milled (engraved) and bent the brass cowling - wow!
Interesting way top offset the motors to allow central pivoting. This will lead to a slight difference in bogie/tandem loading due to torque left and right but probably not enough to cause problems.
In case the motors are not strong enough - I hear you can replace the motor with 380-sized motors, including the rather powerful Speed 400 from Graupner.

[Stuff]

wow that is awesome!

[Hemi1966]

Got the remaining access hatches done and attached :)

[9W Monighan]

Beautiful work. Making the slots in the grill;was that very hard to keep the previous row from bending outward from chips building up?

[Hemi1966]

Beautiful work. Making the slots in the grill;was that very hard to keep the previous row from bending outward from chips building up?

I was afraid that it might do that, but surprisingly the previous row did not get damaged. I did broke a few end mills when trying to take too much one one cut:(
Those grooves are only 1,5 mm wide.

Today I made the blade circle side plates:)

[tc1cat]

This model just gets better and better every time you update the build:eek::eek: Wish there was a way to see it in person when completed:(:(

[9W Monighan]

Very nice work as expected from you. On the mounting holes for the blade; On my antique Cat graders they had a tapered hole in the arms and a tapered bushing on the mold board to take up any play and overall made it much stronger. Here are some photos from my restoration in the works of a grader:
Circle with some other pieces ready for primer. The design of the circle sure hasn't changed much since 1930. I am amazed at how well the angles are bent. Cat must have employed some of the finest blacksmiths in the day:eek:

Your build and skill still continue to amaze me!!!! Great Job!

[JensR]

I had exactly that motor in my 1:14 grader circle rotation, connected to a 1:60 worm reduction and found it too weak. Swapped it for a Maxon motor I had lying around. This works well.
Not sure what your ratio is, probably a bit higher, so should have more oomph.

Just for giggles, here's mine :D

[modelman]

Hemi1966-this is a great model and your machine work is amazing! I have a question. Is this going to be a working model? If so, is the motor on the rotator circle strong enough to handle the digging forces of the blade or do you have a way to lock the rotating circle in position? Looking forward to more pictures.

[JensR]

The gearbox to which the gearmotor is attached is a worm drive, which cannot be back-driven, so the circle will stay in position.

For the full-scale machines a powerful circle rotation is a major selling point, ideally you want to be able to rotate it with a full blade.

I, too, wonder whether this motor will be strong enough, after my own negative experience as a circle drive, but Hemi has a higher reduction, as far as I can see, so while slower, it should have some grunt.

[modelman]

JensR-I know nothing about scrapers but have had some experience with gears. I see in your pic that you are using plastic gears and worm gears. I think that spells disaster. The plastic might last but worm gears are notorious for causing heat and friction. Heat and plastic gears are a bad combination in my mind. If you are not planning on working it hard it may live, but if you rotate a few times with a full load I think the plastic gears will be toast.Just my opinion!

[JensR]

It's a grader, not a scraper ;)

Thanks for your concerns.
The speed is very slow, already before the worm drive, so heat is not an issue.
The white gear is high quality PA. Sadly, the red worm is relatively low grade plastic. As the transmission is currently pretty exposed, dirt can enter the area and that together with the rather high surface pressure between gear teeth and worm will damage the worm over time. So far it has held up very well, though and as it is much cheaper and much smaller than any alternative worm I could find, I'll simply replace it once it wears out. I am currently still in the prototyping and testing phase and will look into doing a shield to keep dirt out.
Without a lathe or mill, I had to simplify the design, but this is not an area I am worried about.

Anyway, as this is Hemi's thread, I'd suggest that if you want to discuss this further, we do that in the thread I opened about my grader. I posted my picture for Hemi to see what I was comparing and I am fully aware that Hemi's grader is in a totally different ball park. But as sizes are comparable between our machines, so should the necessary power and that's why I posted a shot of my low-tech solution.

Cheers
Jens

wow its looking good!

[Hemi1966]

I managed to make the blade and the side shift rails.
Here is a few pictures of making it:):

[Hemi1966]

And to relieve your doubts of the blade turn forces I made this video;). In the video the aluminium block weighs 1,2 kilos:)
Also about the blade hold forces with worm gear are no problem, you cannot turn the blade by hands. As JensR also explains earlier.

http://i327.photobucket.com/albums/k471/Hemi1966/th_Rotation2.jpg (http://s327.photobucket.com/albums/k471/Hemi1966/?action=view&current=Rotation2.mp4)

[JensR]

I really like how you did the blade.

I had massive problems getting mine done. I tried to bend it into shape with a vice and wood blocks :-/
I thought about using a tube, but I am not sure I could cut it clean enough with my jigsaw :( Might have to build a guide for the saw? That could work...
What diameter does the tube for the blade have?
I thought something in the 100mm region would look fine, but yours seem a bit smaller? This would make it a bit cheaper...

How do you mount the blade to the rails?
I have the silly(?) problem that my screw heads are sticking out of the rounded blade surface. It seems you are mounting from the backside with tapped/threaded holes in the the blade. You'll then grind/file/cut the protruding screws to sit flush with the blade?
I've thought about doing something like that when I take apart, paint and reassemble my grader. Not sure I can do this well enough with my tools, willing to try, though =)

The outer black dots in your photo look as if they are screw heads, what are you going to do about that?

Also, your sliding mechanism seems to be aluminium on aluminium - have you thought about brass or teflon/PTFE glide shoes?

What gearing to you have on your circle rotation (excluding the motor gearbox itself)? It seems slower than my first variant, but more torque, so I'd guess around 1:120?
Your video is impressive - although we do not know the fiction coefficient of the metal/polished wood surface :D

Sorry for all these questions!

Cheers
Jens

[rc_farmer]

That is really an ingenious idea on building the blade. you will have some serious cutting power. I don't think you will have a weight issue. I had to add ballast to mine my wheels.

[4u2nv]

What a gorgeous machine you are building there... I can't wait to see it finished and detailed.

[Hemi1966]

Not much to report here, just got the wear blades done:)

http://i327.photobucket.com/albums/k471/Hemi1966/IMG_3491.jpg

[9W Monighan]

That's more than I can report at this time with any progress.
Your wear plates look very nice. One thing,you will need to use countersunk screws on the wear plates.

[mack kid]

Just amazed at this build sets the bar for quaility.

[Hemi1966]

I made the blade tilt cylinder brackets, and the side shift mechanics.

[sneaky-pete]

That is bad*ss....youve got skills!:D

[rc_farmer]

You have MAD-Skilzs, this is awsome!

[cbazq271]

one of the best hand made RC's I hace ever seen.

[JensR]

That looks great!
Is the outward connection of the side shift is not outwards enough, it looks like you have only relatively little movement to the right?
In the original, the brackets sit much closer to the end of the blade.
Is this a restriction because of the hydraulic cylinder?

The movement is actually made by electric motor and spindle, and that restrict the travel. The short travel (35mm both ways) annoys me too, so I´m going to change the spindle to hydraulic cylinder.

http://i327.photobucket.com/albums/k471/Hemi1966/IMG_3500.jpg

[JensR]

Ah yes, that makes sense. Hydraulic will be beneficial there.
Are you going for a rotary feedthrough for the blade tilt and shift?

I use a spindle drive - it works very nicely and I get a lot of travel, but dirt is an issue. I am thinking about converting to a pull-pull winch - not sure, it's just a thought at this time. But for the high quality of your model, I feel that hydraulics is the way to go.

BTW, could you tell me what diameter tube you used for your blade?

Cheers
Jens

[Hemi1966]

could you tell me what diameter tube you used for your blade?

Cheers
Jens

The tubes is diameter 66 mm.

[Hemi1966]

Ok, now I made the hydraulic cylinder for the side shift. It works much better than the earlier spindel , and it now has much more power and travel (50 mm both way).
Only drawback is that I might not be able to route the hoses inside the horizontal tube, and out in the middle:( I had to take them out straight from the nipples.

There is also a small video clip of the side shift, and if you wonder why there is a bucket in the picture, that´s because I took the hydr. pressure from my excavator;)

[Ken Orme]

Hemi1966;

Your machining and photos are excellant. Keep up the good work.

Ken

[sparkycuda]

No words to describe the workmanship, fit and finish. Awesome seems inadequate. You made the side-shift cylinder? Would you be willing to share you construction methods, especially what seals/o-rings and how they are arranged on the piston and head.

Thanks!

Ken

[mazdaparts]

That is much better on the side shift. How are you going to keep the hoses from twisting when you rotate the blade?

[JensR]

So smooth and quick - wow!

[Hemi1966]

Would you be willing to share you construction methods, especially what seals/o-rings and how they are arranged on the piston and head.

Thanks!

Ken

All seals are o-rings. Both piston and rod are sealed with two o-rings. The cylinder tube has threads in both ends, and the end caps are sealed with 3M Hydraulic Sealant HP42.
The most hardest task is to make the o-ring grooves to the cap that seals the piston rod.
My side shift cylinder has 4 mm piston rod, so you need very small tool to cut the o-ring grooves with lathe.
And of course the grooves MUST be in correct size, or they won´t hold the pressure
The picture you see here is not the side shift cylinder, it´s one I made earlier, but it´s made the same way so you get the picture.


http://i327.photobucket.com/albums/k471/Hemi1966/IMG_2489.jpg

[Lil Giants]

What's the tool look like that you cut the inner grooves with in the rod end cap?

[Hemi1966]

[sparkycuda]

Ari, thanks for the technical info about the cylinders. Those inside-cutting tools are really small, but just right for what you are making. Is the rod and barrel material stainless steel? Piston? Maybe I'll try making some cylinders now.

Thanks again.

Ken

[D8R]

Wow, this model is getting better and better. The quality of fabrication is very high, hope to see this model some day!
Dan

[Vanisle]

I have nothing to add except ... that is some amazing workmanship!

[Hemi1966]

Is the rod and barrel material stainless steel? Piston?

Thanks again.

Ken

The rod is stainless steel, but the barrel and piston are made of aluminium.

Past few days I´ve been making the centershift cylinder, and the blade lift cylinder holders.
Next I start to make the blade lift cylinders:)

[elliot330]

Ari, you might have said already, but how many valves/channels you going to be using on this?

Good progress by the way..

Elliot

[JensR]

Your speed and quality are both absolutely amazing!

What ball heads are you using?
I wasn't impressed with the metal heads I found (either not enough articulation or the ball would pop out too easily), so am back to using the Tamiya plastic ones, which are strong enough for me needs...

Cheers
Jens

[Hemi1966]

Ari, you might have said already, but how many valves/channels you going to be using on this?

Good progress by the way..

Elliot
Just made a quick calculation, and it appears the there will be 7 hydraulic functions/valves :eek: + blade rotate control, drive motor control and all the possible electric switches (sound, lights, rotating beacon...):confused:
It appears that I don´t have enough channels on my radio:mad:
I will make all the hydraulic cylinders functional but I might not be able to use them all.

JensR,
I´m using these rod ends: http://store.rc4wd.com/Aluminum-Mini-M3-Rod-End-with-Steel-Ball-1_p_637.html

[JensR]

Thanks Ari!

I take it you are happy with them, so I might consider them if I run into the limits of the plastic ones.

As for controls, I have 13 functions on my grader, more info here:
http://www.rctruckandconstruction.com/showthread.php?t=2056

I have since then added mechanical floating positions for the blade lifts. Each counts as a "on-off" channel on my transmitter.
I will try to get the 6x6 working and will add another ESC for the front wheels, with a mixer relating to the main drive.
I didn't want to spend a fortune and have looked at many ways of achieving this many controls while keeping it operational.
I have opted to go for a modified transmitter set-up, using two Turnigy 9x transmitters - more info also in the above thread. As you can see, this is rather backyards engineering, but someone with your machining skills could do some _really_ nice mounting/housing.
There's also a solder-yourself bluetooth kit from Germany that does a lot of channels: http://www.blauzahn-online.de.vu/
Not sure how good your German is?

I'm not an expert, but in my opinion having easy control of the grader is essential for operating it with fun and I had a good look at actual user interfaces and also some futuristic ones where I found patents.
I personally think that the Caterpillar M-series controls, which I adapted to my grader, are very intuitive and as your grader is a 14M, it would be a perfect fit.
Just an idea :)

Best wishes
Jens

[Hemi1966]

Thank you Jens, I´ll have to check on those.

Made a little video while testing the blade lift cylinders.

[JensR]

Very nice again, Ari!

I like how the circle side shift cylinders fits neatly even at full lift!

I notice a bit of slack when you lift the grader up, but that is admittedly a rather extreme manoeuvre!

What is the maximum clearance between the blade and the ground which you get?

Original has:
Maximum lift above ground 16.5 in
Maximum depth of cut 17.3 in
http://www.cat.com/cda/layout?m=308648&x=7

In 1:14.5 that would be 28mm and 30mm.

Cheers
Jens

I have some temporary loose bolts in all of the joints in the mechanism, so most of the slack is due to those bolts.

I can get the blade 26mm off the ground, and then the center shift cylinder starts to get pinched. Downward it goes about 35mm.

[JensR]

That's great!
I hope I do not sound too critical - I think your project is a dream! :)

[Lil Giants]

You keep posting new progress and I keep watching intentively. :cool:

...and hoping you're making two of everything as you go. :D

[mazdaparts]

Great looking Grader. I'm curious about the weight. I fear you might not have enough weight to make it perform up to your design standards.

[Hemi1966]

Great looking Grader. I'm curious about the weight. I fear you might not have enough weight to make it perform up to your design standards.

I´m estimating the weight to be little over 10 kilograms, is that enough, will just have to wait the test drive results;)

I got the wheel lean cylinder done. It was very difficult task to do, due the limited space for the cylinder lenght. I use only one o-ring in the piston and in the rod seal, to get the cylinder as short as possible. It has total of 18mm stroke. It appears to be holding the pressure (15 bar)
The wheels lean a bit more to the other way, but will just have live with it:rolleyes:

[rc_farmer]

Ari, you are doing a great job. As far as weight, i don't think you will have a problem, since yours is made from aluminum. You're looking at about 22lbs @ 10 kilo. You may have to add some shot to the tire for traction. I have not weighted mine out yet but I think it's tipping the scale somewhere around 35lbs.

Keep up the good work!

[hammer]

Ari, awsome job man craftsman ship looks outstanding your attention to detail is insane can't wait to see the finished product.

[Espeefan]

I'm just dumbfounded by the level of detail and exactness of the parts you machine. I feel like a broken record because all I can keep saying is 'wow'! This is one of the neatest builds I have ever seen.

I just can't design and build as fast as you do. So So NICE! You give many of us inspiration and ideas to build. Bravo!!

[JensR]

Excellent, so smooth and powerful :)
Great how all the functions fit together in the tight space :)

Will be interesting to see how the steering feel is, if the stick position is proportional to steering speed and not steering position?

[rc_farmer]

I am amazed at your engineering and building talent. Can't wait to see it all work together.

[Hemi1966]

I got the blade tilt cylinder done. That´s the last cylinder for now.:)
I have to abort the build process for a while, because we are moving to new a house. I must start to pack my machine shop to boxes, not to mention all the rest of the house... :eek:

It's great to see you back to making progress on this fine project Ari... patiently awaiting further updates with great interest. :cool:

[Hemi1966]

I got the engine compartment bigger top piece done. The piece is curved half of it´s lenght, and I was not sure how it´s going to bend cause it´s 5 mm thick.
I did mill grooves in the underside in the area that should curve to help it bend.
Then I band saw a wood block to the same curvature and place the aluminium piece between them. Next I put it to a hydraulic press and press the wood blocks together (plate between), but as I release the pressure the plate returned straight:( Then I decided to heat the aluminium plate hot and did the pressing again. I left it under pressure to cool down, and this time it did stay in correct shape:)

[9W Monighan]

You don't need to make two dies. All you need is one. Take a piece of soft rubber or urethane (you can get different hardiness) Place the part on the rubber then ram the die. The rubber will conform to the die pressing the metal. This may take some practice on what hardness rubber but the end result will leave no marks on the aluminum piece. I have a long urethane die I use on my press brake that I bend painted aluminum sheet on and the die leaves no marks.
Here's a picture I found on the web of what I was describing.

I'm thinking you should make a second one and don't paint it. Leave it in raw metal look, maybe clearcoat so it doesn't rust or corrode. I can't wait to see the vids of the grader.

[johnboyee]

Awesome job, I operate this beast everyday, just amazing the detail you done so far! If you decided, or had it all on paper, I would buy a set of plans!!

[johnboyee]

Kinda off/on topic, as I'm sitting here in my cab with the radio and a/c on, it jus hit me, it would probably be cheaper(not including cost of machine) to turn this machine into remote control, everything except throttle, and on/off runs through joysticks, a 14 channel radio would cover it! But I think that would be pretty awesome, but nit sure if it would fit in my garage!

[Hemi1966]

Awesome job, I operate this beast everyday, just amazing the detail you done so far! If you decided, or had it all on paper, I would buy a set of plans!!

If you ever have camera with you, I would be grateful if you are able to take some photos of the machine, mainly on the back wall of the cab.

[johnboyee]

I'll grab some shots tomorrow and try to get them uploaded or sent to you, I want tonsay most of the stuff back there is A/C stuff, but no problem!

[Espeefan]

This build is insane! I can't get enough of it. The level of detail is so incredible. A true matster piece in the making. I have to agree that it will almost be a shame to paint and decal this machine up, as it is a work of art!

Just amazing.

[Azonic]

This is one amazing build, respect!

nice details, Ari.
Did send you a pm

Great details! Cant wait to see this in action!

[johnboyee]

That's just takes the cake, great detail, glad I could help...

[Hemi1966]

I started to decorate the cab:)

You are a crazy man! :D

[Hemi1966]

I test fit the valve block and the pump to the grader, and they seems to go in wihtout any problems. I will add second valve block in front of the other and they go so low I can add pump over them and there still over 2 inch clearance to the hood.

Ari, just a quick suggestion. Loosen the set screw that holds the motor to the the pump and turn it 180 degrees to the bottom. That way if there is any pump leakage it will drain out the hole and not gum up the motor. Thanks for showing us that just about anyone can build this caliber of model with just a small shop. Well Done.

I found myself starting from the beginning of your thread once more, today. I just can't over how much talent you have, to create a machine like this. We can't even call it a model because it's not. It's a true, functional, working machine, but on a smaller scale. Unbelievable! What a masterpiece. I think even some the best model builders on this site can't help but be humbled, when they view your thread!

[Hemi1966]

I started to add the hydraulic hoses, first I install the steering related ones.
Theres going to be a lot of hoses when I´m finished :eek:

I'd paint this thing before I'd plumb it, gonna be mezzy taking it all apart afterward. :eek:

Will mine be ready to ship in the new year? :D

[Hemi1966]

You are right about that, but with this one I want to see that if it even works the way it should, before painting. It´s easier to do the needed modifications when you don´t have to watch out the new paint job.

[Azonic]

Looks amazing as always! About the paint, just spray it all yellow when all hoses ar installed, then go bash it! :) J/K

[Hemi1966]

Got some more plumbing done :)

Nice job, cant wait to see this thing move! :)

[Espeefan]

Boy that is a lot of hose! Your doing great with routing it all, and keeping it tidy with the anchor points and hose retainers. Very clean.

[Hemi1966]

Hoses, hoses and more hoses...:eek:

UNBELIEVABLE!!! Keep up the good work and keep us all posted with updates.

-Terry

[Azonic]

****!! How many meters of hose have you used so far? And all those tiny fitting mounts for the hoses, youre a mad man, in a good way! :)

[9W Monighan]

Hosing nightmare!!!!:eek:

[Hemi1966]

I got the hoses pretty much hidden, however the mess is at the back of the machine now.

It's an incredible level of mastership that you offer to us! When I'm thinking of all the machining work, planning, designing and everything it involves, I'm speechless... Great great job! Thanks to share!

[Lil Giants]

Now what did you do to pair up all the hoses at the back? Tape them together...

What size tubing is it? 1.5mm throughout?

I taped the hoses together. The inside diameter of the tubing is 1mm.

Here is a video of the 14M running first time whitout hydraulics:)

Ari,

I've been following your project, I have to say that perfection is expectable that you realize the project. Congratulations!

In cutting blade you used linear guide which model was it?

Thank you,

Carlos

[Espeefan]

Great video! You've got to be really happy and proud of your work up to this point. This is amazing, and great to see the model moving under it's own power. The turning radius looks great, for it being so long.

[Lil Giants]

Other than tires, bolts & other miscellaneous bits, you've built everything to this point, well done Ari! :cool:

Are you making your own pump & valves too?

[Trucker47]

Hey awesome looking build! I have been following it since the start and it always keeps getting better! just wondering though, where did you get the tubing you used for the hydraulics?

Thanks, and keep up the sweet work!

The tubings are from Leimbach modellbau: http://www.leimbach-modellbau.de/

Thank you so much! I sent a e-mail for a quote but I had to use a translator so I hope it makes sense to them :/

[Azonic]

This is one amazing build, such an talented builder you are, respect!

Cant wait for more!

[crawler07]

wheres that jaw on the floor emoticon I know its around here somewhere,,,,Awesome in aver aspect!!!!!

[Hemi1966]

I made more cab interior parts while waiting some hydraulic parts to arrive

I love looking at this thread every time there is an update. This is just like eye candy. The dash looks great and very clean. I do have to ask though, what did you use for the pedals or did you mill the ribs into the brass?

Tyler

[Hemi1966]

Tyler

I couldn´t find any ribbed plate, so I had to mill the pedals from 1mm thick brass.

[Hemi1966]

Hi guys, just got my internet connection up and running, my modem was broken:mad: It took me almost a week to get it working:o

During the past week I got the hydraulics working, and made few driving videos.
I will uppload those soon:)

Wow, 8 servos, i have 3 in my excavator! :) Looks great as always!

Looking forward to see the videos!

[9W Monighan]

That hydraulic system is mind boggling to me. Must be confusing making sure the correct tube goes where it's supposed to go. If you didn't already say in the past may I ask; What motors are you using? Reduction? RPM? torque output?

[Hemi1966]

Here are the videos:):
