CAT 374D L

[Hemi1966]

Looks amazing Ari! I'm not sure if I missed the info but what are you using for the hydraulic pump and valves? Are you going to make your own?

Keep up the great work!
Reg

I'm using Jung pump and Kampfer valves: http://www.123modellbau.de/modules/wsShop/article.php?article_id=301569&location_id=47&cat_id=52019

[Fierce Hitachi]

Very very interesting build. what pressure will the hydraulics run at?

**edit**

Just seen it, 20 bar. Should have some good digging power :)

[speedy8305]

Ari I have worked on Cat machinery for about 15 yrs and I must say your detail is fantastic keep up the good work I cant wait for the finished product

[Hemi1966]

Thanks guys:)

Here's what I got done today:

[D8R]

are you milling those square holes on engine doors and anti skid plates?
With 1mm end mill or??

[Stefan]

Parts, parts, parts... so excellent!!!!

Ari, did you plan the complete support structure for the panels in advance or do you decide as you go along?

[Hemi1966]

Those square holes are milled with 1.5mm tool and skid the plates with 3mm radius mill.



Ari, did you plan the complete support structure for the panels in advance or do you decide as you go along?

I had some vision in my mind but it often changes on the way:)

Got the rest of the anti-skid plates done and also the hinged center section of the engine cover.

Oh :o, now when changes glasses I can see the radius on the square holes. Looks familiar with holes on my hood, guess they have same supplier there.
What speed can you go with a 1,5mm mill? 4"/min??

[kerst]

The attention to detail is amazing!

Kerst

[Espeefan]

Wow. I am at a loss for words. This is another great Caterpillar model, built with incredible detail. A work of art, that will really work, when done!

[Newcastle]

Hi. Great build. What kind of rpm are you looking from your motors after the reduction?

[tracksntreadslou]

Coming along Nicley Ari ..Your attention to detai is awsome ..Pretty much giving it your own signature with all the little changes ,extras and add ons ..When your milling out the smaller holes can you pretty much cut through the thinner guage material or do you have to make multi passes with those fine bits..Feed rates make a difference as well? Thanks Ari and Nice work

With those smaller bits I like to take several small passes with a higher feed rate.

Today I managed to make the upper cooler grill:)

Looks fantastic Ari! It won't be long now!

[Hemi1966]

Looks fantastic Ari! It won't be long now!

Thanks Reg, I hoping to get the hydraulics up and running in few weeks, just missing filters and the tank.
I'm anxious to see how my cylinder will hold the pressure:confused:
To be honest there's still a lot to do, and it always seems to get harder and harder towards the end.

Here's the lower grill:)

[ihbuilder]

awesome job so far Ari . Question, did you order your internal gear online ? The site states they only except online payments from the UK . And of course , the 1's I need are not in stock .

[Hofabooz]

Hi

What a great model your attention to detail is amazing, thanks for sharing with us all, looking forwards to seen this progress.

Regards

Mark

[Hemi1966]

Yes I did. They will send you a invoice to your email and you must pay that in advance.
It's simple to do in Europe when using those IBAN and BIC numbers but I don't know if are you able to use them when paying from outside EU.

OK I'll try them again . worst case I cut them myself . I already have it programmed . It's just a good couple hours to cut in the mill in steel .

[rc entreprenøren]

This is the greatest build ever. This machine is going to awsome...

[Hemi1966]

Slow progress:)

[John T.]

WOW i am sooooooo jelious. such awsome work it just blows me away wow!!!!

[Hemi1966]

I got the hydraulic system up and running to test leaks and found one on the stick cylinder tubing:o I fix that and made a little video of the test run.
There's 7,2 kg weight on the bucket and it seems to have much more lifting capasity, all though it need lot of counter weight:)

http://youtu.be/M9QHtM6sdxI

[D8R]

will you manage counterweight made in alu or have to do in steel?
Good looking steps.
Guess by now that you are an expert on programing!
Dan

[Azonic]

Finally its moving! :)

Not to bad with only one leak, looks very smooth in the hydraulics!

[Lil Giants]

Just one leak?! ..that's pretty good on start up. :) The real test will be when you're working the snott out of it for a couple hours straight, maxing the pressure constantly! :D

[elliot330]

awesome job so far Ari . Question, did you order your internal gear online ? The site states they only except online payments from the UK . And of course , the 1's I need are not in stock .

if you need anyone in the UK to order stuff and forward it on, then let me know, don't mind helping fellow modellers out..

Elliot

I'll keep that in mind Elliot :) thanks for the offer . I found a co. state side that has 1 in stock . Same price when converted .

great job so far Ari :) your truly an inspiration for me to get my but in gear and get 1 of mine done :)

[Hemi1966]

will you manage counterweight made in alu or have to do in steel?
Dan

I propably must put led inside:)
I would have never believe that this thing can have so much power, I was just lifting a full size car tire with steel rim which propably weighs around 20kg:eek: and it didn't even struggle.

[Lil Giants]

That's a bit extreme, what do you have the pressure set to?

[Hemi1966]

That's a bit extreme, what do you have the pressure set to?

I'm at 22 bars now.

[elliot330]

Nice work as always Ari.

I guess it's so powerful due to the size of the rams? Am I correct in thinking that the bigger the ID of the cyclinders the more powerful they are?

What's your thoughts on the Kampfer ventil/valves?

[Hemi1966]

Nice work as always Ari.

I guess it's so powerful due to the size of the rams? Am I correct in thinking that the bigger the ID of the cyclinders the more powerful they are?

What's your thoughts on the Kampfer ventil/valves?

Yes you are right Elliot, larger diameter cylinders are more powerful.
On the down side they also need more capasity from the pump and also larger hydraulic lines.
My cylinders have 18 mm bore, so they are not that large.

I'm very pleased with the Kampfer valves so far:)

[izzzul]

superb work here...! really amazing to look at..again and again..

[Hemi1966]

I've been working with the counterweight and it's turn out to be nightmare to make:mad: I wish I were able to make it like Steve (ihbuilder) in one piece, but my cam program won't do 3D (I think)
I also did some welding on the counterweight with Durafix but it really does not work well when you have to brace different thicknesses together. The thinner plate tends to expand more while heating and it goes curved, and when everything cools down and shrinks, it doesn't look too good:mad:
I'm seriously thinking about buying small TIG welder, it looks like you can make very small welds with it without heating the parts too much. Been watching Reg's Kenworth 850 build and hope I can some day learn to weld that well:)

http://i327.photobucket.com/albums/k471/Hemi1966/CAT%20374D%20L/IMG_1022_zps931c60b5.jpg

[JAMMER]

Ari you have nothing to be ashamed of when it comes to your work you have a talent. Ed;)

[RCP57]

Thanks for the ego boost! I think a TIG would serve you very well Ari. It can be a little challenging at times especially when welding two different thicknesses of material(at least for me). It would be nice for you to be able to weld together some things instead of drilling and threading for fasteners. CNC cut panels would weld together sooooo nice! Keep up the great work! This machine is awesome!

Reg

[dabears]

Ari anything can be fixed with filler and paint. ;) your build is killer looking!!!!

[Madda]

Ari, great job there!

Maybe you should get better CAM? Also for that one part, why not try a demo of some powerful program? You could get the part done even if you don't buy the 10k per year CAM system :p :eek: Just some thoughts;)

That shiny aluminium looks so good, maybe you don't paint it?:D

[ihbuilder]

Ari , what cam are you using ? I had a few issues at 1st but the more I use it the better I get .

[cdm]

Ari anything can be fixed with filler and paint. ;) your build is killer looking!!!!

or in that case aluminum flux, then power sand down on the belt. has like 30000psi strenght vs 2000 (at best) for filler.

given all i've seen im surprised thats all the items that didnt come out right. you are way better than me thats for sure

[Hemi1966]

Ari , what cam are you using ? I had a few issues at 1st but the more I use it the better I get .

I'm using this: http://www.industryarea.com/Metal-working-machines-Y918-S148-catalogue.html
It's very simple to use but it has it's limitations:(

I did some plumbing work:)

How much does it weigh now?

[Hemi1966]

It weighs 24 kilos now without batteries and counterweight fillings.
When finished I believe it will be close to 30 kg.

Ohh, so its that heavy already, that will be a good weight for digging i think, it should be very stable! :)

[speedy8305]

this machine is AWWWWWWWWWWWWWWWesome

[Hemi1966]

I started to fit the pump and the oil tank to there place. I also mount the valves. I will attach one more block to the valve assembly for some future needs.

[Hemi1966]

I work with the undercarriage today:)
I chanced the track recoil springs more stiffer and adjusted the tracks to correct tension. I added pair of track guides too. Also there was many :eek: bolts and spacers missing which I added.

[SmallHaul]

Incredible work on this machine. The build quality and detail is just over the top!

Don't ever paint it...just clear coat everything and leave it bare.:D

[caterpillar]

THE best build I have seen so far on all forums !

[Hemi1966]

Thanks guys for the nice words:o

I got the fourth block to the valve assembly and made some more work with hoses:)

So what is the plan for the fourth valve? Top secret?

[Snochaser]

Hi-flow for a mulching head? Eh?

[Hemi1966]

I actually have no plans for the extra valve yet, it's just easier to put it there at this stage:)

[RCP57]

Sure keep it a secret!:p

[Lil Giants]

Add a couple more "dummy" hyd lines for electrical accessories, like remote quick-tach coupler and/or screening bucket. ;)

[carp]

Amazing work, looking at your pump drive is it belt driven? if so what ratio and motor are you running?

[Espeefan]

Wow! Simply awesome. Everything is so clean, so well designed, and so scale, it's just unbelievable! I've truly gotten my scale model fix for today! It should last me the rest of the week.

[Hemi1966]

I got all the hydraulics and batteries (two 3S 8000 mAh lipos) stuffed inside the 374 and made a little demo video:)
Next I might go and dig a few holes in the garden ;)

http://www.youtube.com/watch?v=E8w0vaLaLPw&feature=youtu.be

[Espeefan]

Beautiful! It runs as nice as it looks! Looking forward to seeing it digging in some dirt.

[speedy8305]

That is one of the greatest scale models I have ever seen have you though of making a quick coupler for it and additional attachments?'

[Hemi1966]

Thanks guys for your nice words:o:)

I made another video with some load in the bucket (as Joe hoped), and move all the cylinders at the same time to show the speed of the hydraulics.
It is not too fast, but I can live with that:(

http://www.youtube.com/watch?v=elrylkFa55E&feature=youtu.be

[cdm]

I think the speed is perfect!

[jazza]

I think hydraulic speed is ok :) , by the way Ari can you show me your cnc tool it's made a perfect job with your best skill.

[Valdosetti]

Hi Ari! You have created an incredible model so far and I believe to share the same thoughts as everybody also in the forum. You are going to finish it at its best just the way you do every time. You are very talented men and always adding extra star to the forum. The speed is just perfect, it’s a big machine and as that, it`s suppose to have more power than speed and you already have it. I do have question dough. Do you have plans to make it just for you as a hobby or planning to produce it so we can have that pleasure too? Thanks for sharing your talents and hoping that you have lots of enjoyment with this unique machine of yours.:)

[Hemi1966]

Hi Ari, your speed is just perfect. In your opinion, what RPM is the best? I am planning per minute 1,000 turns. Your 374D is just perfect.

I'm not sure what is the best rpm for the pump, and I haven't been able to measure the rpm mine runs. I have this motor running the pump with about 3:1 reduction
http://www.hobbydirekt.de/Robbe2/Robbe/Elektromotoren/ROXXY-BL-OUTRUNNER-4250-07-Robbe-1-4781-4781::78196.html
It starts to produce 10 bars at very low rpm, the max pressure is set to 30 bar now.

Thank you for the compliments Valdosetti:)
This is just a hobby and I don't have any plans to start a mass production of these machines.

[Hemi1966]

I dug my first ditch with the 374:)
It work pretty much as I expected, but the operator still has lot to learn:rolleyes:
I will make a video of it later.

Nice work Ari. Do you plan to make any other buckets or a ripper?

[Hemi1966]

Nice work Ari. Do you plan to make any other buckets or a ripper?

I will make some more attachments for the machine. I wish I had a ripper today, the ground I was digging had lot of tree and grass roots:(

[tracksntreadslou]

Looks good Ari ..That looks as though its pretty packed earth you were digging in ..A good test ...im sure it could well compete with the bigger fumotech models ..And just in time for the warmer weather ..Are you almost ready to tear it down and give it a coat of paint ?

Thanks:)
The ground was quite hard packed. That's my parents yard i'm digging, and my dad told me that that spot has not been touched in 20 years.

There's still work to do with the cab, I'm about to purchase a tig welder to get that done.

So here's the video I promise, as many of you have noticed:)


http://www.youtube.com/watch?v=WBerCOj14-w

[RCP57]

Whooo hooo! TIG!!!!

How wide is your bucket Ari? Looks like it digs very well as expected!

[Jared]

That's great! Looks like it's time to install a new water line, phone line, or sprinkler system now that the hand shovel is obsolete :D

[Hemi1966]

Whooo hooo! TIG!!!!

How wide is your bucket Ari? Looks like it digs very well as expected!

The bucket is 145mm wide, and it would have been much easier to build if I had that TIG back then:D

It is an awesome job you have done here!:D

[Hemi1966]

Hi Ari, how much does it weight now? You're unreal. My undercarrage is finally completed...super heavy. I will post vedio when I get home. Cheers,
Kevin

Thanks Kevin.
It weighs 30 kilos now:)

[Hemi1966]

I made ladders and some steps for the 374:)

Very nice Ari! Seeing you add finishing touches like that makes me wish I had done more detail work on my Volvo. I'm always afraid that stuff like that will get damaged while carrying it around. I guess it won't get hurt while it's just sitting on the shelf beside your grader...:p Haha, sorry that was a Joe comment:rolleyes:.Hahaha I'm not really one to talk. I have more fun building than playing....

Reg

Wow! That was so pretty. Ari, I bought 2 blocks of hard Aluminium 7075 for boom structure. Is there any specific shape of "bones" to support boom? I just felt not many people build excavator here.
It seems that you are using 6mm tubes for Hydraulics, is that 4mm inside?
Many thanks!
Kevin

Are you going to make the boom out block that you machine hollow or how?

My cylinder tubes are mostly 5/3mm.

[Hemi1966]

Very nice Ari! Seeing you add finishing touches like that makes me wish I had done more detail work on my Volvo. I'm always afraid that stuff like that will get damaged while carrying it around. I guess it won't get hurt while it's just sitting on the shelf beside your grader...:p Haha, sorry that was a Joe comment:rolleyes:.Hahaha I'm not really one to talk. I have more fun building than playing....

Reg

I know I should use my machines more, but I guess I like more of the building process.

And about those details, they really are fragile, made of 2mm brass rod they bend quite easy:mad:
The carrying it is the most dangerous moment for the details, it's so heavy you have to keep it close to your body and everything that sticks out might get damaged:mad:

[RCP57]

I think I would enjoy playing with my models if someone else was around to join in the fun. I don't really live near anybody that's into this so it's always just me by myself and I get bored really quickly. When I'm in the shop though I want to be left alone so that I can concentrate! My Volvo fits in the trunk of my car but you have to tip it over quite a bit to get it through the opening. If it had detail like yours it would most certainly get wrecked. I have too many big models to move now though so I guess I will be using the pickup truck from now on. Lots of room there but wide open to the elements and burns fuel like it's going out of style!

I made ladders and some steps for the 374:)

The step you have made.(the one at the top) Can i ask you to make me 2 pieces fo my Cat 345 D LME. I dont have the machines or skills to make them.

You can also send me a PM.
I really enjoy your master work...

[Hemi1966]

I started painting the 374:) The counter weight got color first.
I still have the cab unfinished, I need to purchase a tig welder for that soon.

Whoa! I likey! When is that TIG arriving Ari?

[rc entreprenøren]

Hei Ari.

Impressive work as allways. This machine is going to be just as nice that your grader is...keep up the goooood work.

[Trucker_Jo]

:eek: Oh dang this is going to be so awesome.:D

[Hemi1966]

I am so impressed of the work you are doing.
This machine is going to be awsome. Im looking forward to se the machine painted. and ready to dig....:D

[tracksntreadslou]

Hey Ari congrats on your Build of the month win ..Definatley well deserved..Are you priming the aluminum before paint and if so what primer do you use.. By the way what you have done so far looks great..I would be nice to see a photo of this machine next to your grader for a size comparison .

I'm priming the aluminium with Mipa rapidprimer spray.

Here's a picture of the 374 with the grader as you request:)

Wow .It is quite large..It almost Dwarfs the grader ..I didn t relise it was going to be so big in that scale ..really puts things in perspective ..Thanks Ari

[Lil Giants]

Is that shelf dust or work dust on the grader? :p :D

[RCP57]

Wow, you need a bigger grader....

I finally got the TIG:), still need to get the argon bottle and then start practicing:eek:

Woohoo right on! Looks like it has a lot of adjustments. Now hurry up and weld that cab together.

[Lars S]

Hey! I thought Kemppi was Finland! ;-)

It is, but it's over my price range:mad:

thanks perry

[Hemi1966]

Not much to report here:( I've been disassembling the excavator for easier painting.
I also have been practicing tig welding with varying success:eek:
I can weld aluminium over 2mm thick, but I'm struggling with thinner materials when welding corner and but joints. Especially when the other part is narrow and other is bigger I tend to melt the narrow part through :mad:
I was trying to weld the cab side to the front window frame which is about 6mm wide and it melt through:(

[RCP57]

I've definitely been there! The only difference is my pieces weren't as pretty as yours before I ruined them.lol You would think that it would be easy but it's really not. I think I have improved with time(you will too) but I've also learned that there are some things that "I" just don't have the ability to weld. I often weld pieces together before cutting out windows or drilling holes. This often makes the welding possible but the hole cutting a pain in the a$$. I also sometimes make small parts oversize and trim them to the proper shape or size after welding. All that makes the job more time consuming but there is nothing worse than spending hours on a part only to melt a big hole in it and having to start again!

Thanks Reg, you gave me several good advices there. I actually went through your Volvo thread yesterday to see how you did your cab. I will try to make the window frame oversize, that might make the welding easier:)

[Hemi1966]

Excavator parts degreased and ready for painting:)
Here's everything except the hydraulic lines.

Truly a masterpiece!

[speedy8305]

Darn this paint needs to speed up lol cant wait to see the finished product been watching this awesome build since post#1

[Espeefan]

With your parts all cleaned and degreased, laying out on the bench.....it gets me wishing this was a kit, and it was laying on my workbench! :D

[speedy8305]

Yea that sounds like a good Idea you should turn it into a kit (reasonablly priced)

[RCP57]

Looks like you got that cab welded up. How do you like the welder?

[Hemi1966]

Looks like you got that cab welded up. How do you like the welder?

The cab is not done:mad:, what you see in the picture are just some cross members that I welded between the sides to help welding the actual outer surface, that I haven't even done yet.
The welding machine is ok but I still have a lot to learn:o

You'll get it. Does the welder have a pulse setting? I find it helps to use it on the thin stuff sometimes especially with longer beads. I am using .050 5052 aluminum on the boat that I'm working on and it seems to weld OK but I definitely have to be more careful than with the .063 that I'm used to. How thick is the cabs sheet metal?

[Madda]

Beautiful job, can't wait to see the final product!

Ari, when you make parts with your BF20l, what tolerances do you get usually on the parts?

[Hemi1966]

Beautiful job, can't wait to see the final product!

Ari, when you make parts with your BF20l, what tolerances do you get usually on the parts?

I can get under ±0,02mm tolerances when everything goes perfect;)

[Madda]

I can get under ±0,02mm tolerances when everything goes perfect;)

Wow, that is really tight:cool:

Do you have so perfectly configured/modificated machine or you have some trade secrets that you use to get that tolerance? I can get something about 0.05mm usually on my parts, if all goes well it is sometimes even 0.01mm, but it really varies on part to part.

I have ball screws in all axis and the cross table dovetail guides relatively tight to have minimum play.
I also make several final passes to compensate tool flex.
But like you said it won't always go so well in every parts:(

[Azonic]

That's beautiful Ari!!

If I had to choose I would have narrowed the tracks a little more, but that's just my personal view of it! :)

Amazing work, can't wait to see it all painted!

[thercfreak2012]

wow them tracks look amazing

[nutmag]

Where do you get these blueprints?

[tracksntreadslou]

Looks very good Ari nice work..Using the scale fasteners really makes a difference and gives the model an extra touch of realizm..Do you buy yours local or have them imported from micro fasteners..You sure have alot on this build with the tracks ..

[Hemi1966]

Where do you get these blueprints?

I have no official blueprints, just those measurement drawings from the 374 brochure. The Norscot 1/50 die cast model has also been helpful.
I also been studied hundreds of photos of the machine.

it looks like it just come from the caterpillar factory brand new

[Espeefan]

That's beautiful! For not having actual prints, your Cat 374D L looks highly accurate. I really like the engine bay louvers, and the way you painted the black stripe right over the top. It looks great. Very scale and realistic.

[speedy8305]

**** it Ari you are too good for words

While the paint dries I made some rock guards for the cab:)

Nice job on the interior! and everything else of course!

At least if you ruin some parts while welding you can make them again exactly the same since you have cnc. I do understand your frustration though!

[rc entreprenøren]

Hello Ari.

This is truely one moore master piece made by you. :)
I look foreward to se this finniched.

[Hemi1966]

Hi Ari,
Awesome and extremely detailed. I am having problem to seal the join completely...between cylinder and tube. I cannot blaze this area since hydraulic tube already attached to cylinder. High heat will burn out tube.

Kevin, you might try soldering it with normal tin, it melts at lower temperature and doesn't melt the brazing. You need a gas torch and you must get all the oil of the seam.

Got the cab painted:)

This is an amazing piece of machining art:D I'm sure you are excited to see the project come together and sad at the same time . Bet your more excited than sad:)

[nutmag]

Absolutely fantastic. Your are a amazing builder.

[TRUCKMAKER]

Turned out excellent of course, really like the interior detail. Can't wait to see some video!

[Actros4160]

Amazing job you have done with that Cat374.

Regards,
Bernd

[bruce]

That is a master piece well done

[apfubar]

Well done very nice!

[footprint]

Wow well done thats amazing, really just well done..im off to cry you've really set the bar on this one.

[speedy8305]

maybe you should tackle a hydraulic hammer,grappleror some shears for that beast

[Ramon]

This is absolutly a master piece, top build. I like the details.:)
whats next?

[JAMMER]

You have performed an amazing piece of work with a lot of fine detail. Your documentation was great to say the least. There is a lot of excellent Ideas in your build, thank you for sharing with us. Ed

[Hemi1966]

I made a simple quick coupler for the 374. I made so that it fits to the original bucket with out modification. It probably isn't correct CAT style but will see how it holds up:o
I haven't the correct hydr. lines for it yet, so I've only test it with air and it seems to work.

[RCP57]

Wow Ari, beautiful machining as always! I like the fact that it is very low profile. It seems that some of the couplers are quite large and must effect the buckets breakout force.

Reg

[Acadieman]

Nice addition!
The details on the plate makes it stand out.

[Lil Giants]

Well you're just on fire now! :eek:

I can see problems with that design with the holes not lining up just right & some outside interference (your hand) needed to make sure it locks fully into place... somebody I know has designed and built the ultimate failsafe coupler, maybe he'll share his secret with you for a 100% hands free lock into place every time. You're on the right track though, but you just need to redo a small part of it. ;)

I tried make it so that when I crab the bucket to the coupler and twist it, the holes line up automatically, but of course I'm open to improvements :)

[Azonic]

Wow, very nice coupler Ari, that's the same way the new Premacon coupler locks, should work just fine! Great job!

[Lil Giants]

Wow, very nice coupler Ari, that's the same way the new Premacon coupler locks, should work just fine! Great job!

Well I was giving props to what you did Kalle, your coupler works flawless... I've done it hundreds of times now and no hand adjustments to get it to fit & lock or release. The only thing I'd consider changing is going to hyd actuated for a quicker change & no worries of the timed esc to get out whack and burn out the actuator motor.

[Stuart]

A work of art and simply gorgeous, well done.
Stu

[Hofabooz]

Wow Ari
That coupler looks great nice job.
Thanks for posting all your progress makes a great read and insperation.

Mark

[Hemi1966]

I got the coupler working with hydraulics. Here's a video of the test:
http://www.youtube.com/watch?v=byGaVoVXWA4&feature=youtu.be

[Stefan]

Works perfect! Thank´s for the video, Ari! I agree with all the other guys: This has been an incredible build. I really enjoyed following it.

However, as said in the video comment - the bucket is already dirty, so where´s that video? :D:D

Regards
Stefan

Ahh, thanks Joe, good to hear it still works for you! :) I would have gone hyd. if i had the tools/knowledge.

Ari: Are you going to route new hyd lines for the coupler on top of the stick, under the cylinder?

[Hemi1966]

Here's a short video of my 374 loading Scania tipper:)

More of the same from a different angle:)

[Lil Giants]

A mighty fine machine you have built yourself Ari, anybody who didn't know you built it would swear it must be an EC-M model. :cool:

Now it just needs some fine tuning in the radio so the valves aren't so sensitive/jerky. ;)

[Old Guy]

Ari Outstanding build I'm near the end of my RH400 mining shovel build with hydraulics for cylinders so I know what you have gone through. Now you next problem is what's next, as like you and many others the building is the most fun.

Earl

[Hemi1966]

I took the finished 374 out to take some photos before it starts to snow:)

I'd like to thank all of you guys for your interest and compliments to this project.
It feels some how empty not having anything construction machine related going on right now:( ,so now I must decide what next, what would you guys like to see;)

[RCP57]

I would like to see you build a haul truck to match the excavator. I think you could put one together quite quickly with your skills!

[Snochaser]

I'd love to see a Cat 637 or 657 scraper.

[9W Monighan]

I second the haul truck idea. CAT 777?

[Azonic]

Amazing end result!

How about a Ponsse harvester or forwarder? Match good with "Made in Finland"! :)

[speedy8305]

CAT D11 or a Scraper or paossibly a 777 with your skills anyone of these is possible

[Espeefan]

Another fine masterpiece Ari. The 374D looks great outside in the natural sunlight.

How about you tackle a Caterpillar 527 skidder next? That would be something totally different from what you've been building.

[Lil Giants]

A haul trk would be a positive asset to compliment your track hoe, but...

I'd love to see a Cat 637 or 657 scraper.

..just like your 14M grader, nobody else has done one of these yet! And with your skills to build, no one will do a better job than what you're capable of. This project should keep you busy for a year again. :D

[steamer]

My vote would be for a Cat 657B. With the twin motor setup you'd be able to power both axles and really move some dirt!
Rob

[ihbuilder]

Great job , Ari . A 657 would be my next suggestion . as Joe stated ,not many motor scrapers attempted . thus the reason for me building the IH 433 pay scraper.

[RCP57]

A scraper would be cool...I like HIlite green:D

Not trying to hijack your thread Ari but with all this scraper talk I thought I should add this. I sub to this guys Youtube channel and he just posted these this morning. http://youtu.be/pLkSYv2fOOw http://www.youtube.com/watch?v=mMXvYNal_dM

Wow, that's cool, but it sounds like it has some gear mesh problems at times.

[JAMMER]

That was quite an animal it had a lot of detail. He did not build that over night. There is quite a bit going on with it a very nice build. They keep getting better and better. Ed

[RCTech9]

Great work Ari, my vote also goes toward a grader.

[jack van]

I machined the tracks narrower, they are now 72 mm wide which is around 1 meter wide in full scale.
For my eyes they look more realistic now.
Here's a picture of the left track still wide.


http://i327.photobucket.com/albums/k471/Hemi1966/CAT%20374D%20L/IMG_0801.jpg

hmm i like the wider version your awsome craftsman

[Alokocat]

Wo'nderful skills to bulle thismasterpiece ! Contrats.

I'd vote for the cat 974C, the meanest looking track loader ever built :D
In your hands it would be like a dream comes true.

[Jared]

I vote for a scraper! Doesn't matter what color it is.

[speedy8305]

As the crowd chants:Scraper,Scraper,Scraper,Scraper

[Fired up]

Very nice.

[tracksntreadslou]

Im liking the scraper build as well or a Cat D9 or D8 Dozer ..Im sure what ever you come up with it will be outstaning

[Sloan]

Wow what a fantastic beautifully engineered model,

Does anyone know the dipper/stick width of the 374d where it connects to the bucket,

Thanks
Steve

[ederson]

Sugiro a motoniveladora 140k cat feito por você ficaria perfeita

[Hofabooz]

Hi Ari

Please make what ever you like as long as you share it with all of us on here.:)
It has been a real pleasure to watch the model evolve to completion.
Really top class work.:)

look forward to hearing what you have chosen and in time the first posts of construction.

Thanks Mark
:)

[od jhon deer]

where did u get tires an wheels for the motor grader wished I had your talent on the excavator really nice job u wouldn't share your blue prints and measurements would u

The tires are from Premacon, but the wheels are self made.

[joao]

Good afternoon friend. U have your project in Cad for CNC, I wonder if u could help me with a project I have, I'm a student of mechatronics in Brazil and tou trying to mount a backhoe min, if u can help me by sending me the files in Cad for min. JP .....

You should build the 777 with a coal hauler. Plus you could make a trailer to haul your excavator and or other equipment.

[namckth]

very nice...

[GraKir]

Inspirational projects, do you have CAD files available for this?

[Lil Giants]

So have you made any dust with this machine in the last yr, or is it just collecting dust?

I've been hoping to see more videos of your 14M... that'd sure be a great asset to the Lil Giants fleet & put to good use. ;) :D

It's mainly collecting dust, but I'm hoping when I get the A40 finished some day, I will start moving some dirt;)

I sold the 14M over a year ago, so no more videos by me:(

[Lil Giants]

Really?! :( You sell it within your region/nearby? Does the new owner use it & post videos somewhere?

[egronvold]

It's actually in Norway now. I've seen it on a few videos on Youtube.

[Lil Giants]

Do you remember which ones?

[Hemi1966]

I took the 374 with me to our summer cottage and the idea was to practice digging and make some videos.
But unfortunately after about half an hour it blew one of the return hoses and all the hydraulic oil came out:mad:
The hose clamp made a cut to the tubing and that was easy to fix, but off course I did not took the oil can with me:(
So that was it, I only managed to make this video:
https://youtu.be/djWCJ5yXC3w

[Lil Giants]

Looking pretty smooth Ari, you must have been practicing with it lots lately. :cool:

A nicely treed area, do you get there much during the summers & how far away from home is it? Looks like great soil to dig in.

We spent there about one weekend in a month, and longer periods in the holiday season.
It's little over two hour drive from home.

This is probably off topic, but here's some aerial footage of the area that I shot with my Phantom 3:)

Smooth operating on both the Phantom and the 347! I agree the terrain looks very similar to us way over here on the west coast. Very cool:cool::cool:

[Otto]

Hei

Ihan käsittämättömän hienoa käden jälkeä. Ja kun seurasin projektisi aikajanaa meillä hallitus kyllä saisi hepulin jos käyttäisin aikaa yhtä paljon omiin touhuinini.. :p

Kunhan ennätän katselen kaikki mahdolliset videosi ko. laitteista.

Onko tällä hetkellä menossa mitään projektia?

T. Otto :)

[Hemi1966]

I'm now using the Servonaut HS12 radio with 3D sticks on this 374 and I love it. I think the controls are more precise when I can rest my hands on the console.
I took a video of 374 while testing the new radio, nothing special, only small drama in the end while the bank collapses while I'm lifting a heavy rock:(
