[rc entreprenøren]

Beatyfull work like allways on your model. One more master piece..

[Snochaser]

This is my favorite of yours Ari if I had to pick. Love it. Great work as usual.

[Bo Wallen]

Ari. When Craftsmanship Shines :) Carry on Please. :cool:

Hi guys :)
I threw the electronics to the still unfinished A40 and made this test drive video.

[egronvold]

Are you sure you just didn't shrink a 1:1 machine? It's just so scale looking.

[Hemi1966]

I took the A40 and the 374 excavator outside and thought that I make a little loading and unloading video, but that did not go as planned. First I blew the oil return hose on the 374 (again) and a little bit later the planetary gear unit on the A40 tear down it self:mad::mad::mad: The bogie axles are in a quite side stress when doing tight turns on heavy load. I was doing a tight turn on a concrete surface and I noticed that the bogie wheels tends to "fall under", if you guys know what I mean. And soon after that one wheel with the hub came off. Apparently the planetary gear outer hub is only press fitted:mad:
No real damages done, but I'm a bit worried will the hub stay in place after I push it in, maybe I use some retaining compound.

[Hemi1966]

What I did to fix the planetary gear problem was I tig welded few spots on the end of the drive shaft, so that the planetary gear hub can't move outwards.

I should have realized that when I was making the axles, but I didn't :o

Hi Ari

Great work as usual loved the new video on you tube as well

[Cooper]

I did some brass work with the exhaust system. I think most of you guys would do these with 3D printer, but as I don't own one yet, brass it is:)

Hey awesome work!! Really!! Do you have a vacuum table? I see the mat material and I know one of the companies uses that material for vacuum fixtuerimg. If so do you like it? Been debating on vacuum vs outsourcing flat parts. Double sided tape has been working but pita to remove!!

Yes I have a vacuum table and at it's best it is great. But when machining a thin materials the mill cutter tends to lift the plate and then it comes loose. By hand you can't move the plate you are machining sideways, but when you lift a corner it's quite easy to detach. I usually run in to problems with under 1mm thicknesses.

[Cooper]

Understand, been using wax and that has lifted a couple times also. Went back to using double sided tape. It's a lot more clean up on table plate and part but haven't had any lifting :).

Glad you brought up the turning forces, I would have never thought of sidewall forces under sharp turns. Really great work your doing!!

More steps:)

Does anyone New where to by this plates Ari uses for steps. This steps with round Hols in.

[trucker n]

He makes them

[rc entreprenøren]

He makes them

Are sure of this...its looks very god...

[bigpipespete]

Nice work , have to admire the talent you guys have who build these machines.

[Northern Farmer]

Check on ebay or google for hobby perforated brass plate.

[Hemi1966]

I did not find plates like that anywhere, so I indeed made them :)

[rc entreprenøren]

Ok. Beatyfull work Innedid.
Ari do you now.
I havet baught the dozer that Unix on this forum ha made.
I planting to powdercoat the parts. But the brass is souldered together. Parts are from 1 mm to 3mm souldered together. Do you think It Will go ok.?? At 190 degrees. For 20 minutes.

I think normal solder melting point is about the same, so you have a risk of melting joints.

[Hemi1966]

I got the first 3D print of the bonnet from my buddy Steve. It turn out nicely, all though it is actually a test print to see how it fits to the rest of the machine.
It needs some small adjustments and after that I think it's going to be perfect:)

[skeeter]

That's an AWESOME looking truck you're building!

[Hofabooz]

Hi Hemi

Looking great the 3D print complements the machine perfectly nice work.

Looking for forwards to seeing this work progress..

[TRUCKMAKER]

Looks real good Ari, the hood turned out nice and should finish off perfect!

[Snochaser]

Can’t wait to see this completed Ari.

[bigpipespete]

How much time did it take to get that hood so smooth ?

[Hemi1966]

This is the latest fixed size bonnet, it took 35 hours to print:eek:
Thank you for that Steve:)

D@M! That's a marathon print job there. It looks nice.

[bigpipespete]

What is the difference between this new hood and the other one ?

[Hemi1966]

What is the difference between this new hood and the other one ?

The first one was too wide and too short.

[Hofabooz]

Hi Hemi

3d Print is looking good cannot wait to see this build all come together.

[Ultrashort]

Hi guys !

Sorry, but should it be that I am the only one who can't see any pics of this marvellus building :confused:?

I use firefox as browser and saw the pictures the last time. Nothing has changed at my pc system.

[Ultrashort]

?????

Sorry but who is talking about buying this model ???

I want to see the pics of the built, which have been there.
Now the have gone and i dont know if i am the only one who cant see any pics or not !

[Lil Giants]

I see all the pictures on this thread using google chrome & this fix

Hi Ari,
Are you using the M-5H-4 2.5/4 size fitting from SMC or the M3 one's. I am starting my hydraulic system and decided to make my own pump because I am in the US and don't have many options for hydraulics or manufacturers of the micro size products like Germany and France, Plus I like a challenge. I have made my CAD design and want to start soon but was wondering if you could share some pictures from your models on how the pump and motors mount together. I would be happy to message you my drawing if you wanted to take a peak. Any pointers would be much appreciated coming from you.
Thank you,
Jeremy

Hi Jeremy,
the Volvo's dump cylinders have M5 fittings and the steering cylinders have M3 one's.
The Volvo have a direct drive pump with planetary gear, but I haven't took it a part, so I don't know exactly how it's put together.
My Cat 374 has toothed belt drive.

I'd love to see your design.

The inline from Kampshoff Hydraulics is a planetary reduction @4.5 ratio

[Hemi1966]

For a long time I did something for this. I draw a new bonnet for 3d printing. It's just printing. Printing time 32 hrs, now at 23 hrs.

Do you get paid by the hour? ;) Yet another awesome build.

[Zabco]

What slicer are you using? I don't think I've seen support structure like that before. Looks like it would be much easier and cleaner to remove. Great work as always.

I'm using Cura, and those are called tree support.

[Hemi1966]

Ready and supports removed :)

The motor I'm using is the LPR Truck Puller 3

The gearbox is Veroma 3-speed

There's a self made dropbox after the gearbox:
