Hi there and welcome! I hope you find the truck you're looking for. I have a collection of TMs for that reason :ROFLMAO: You mentioned you're a USAF aviator - can you share what aircraft you're involved with? When I was in high school I seriously considered joining the Air Force after...

Acetone vapor smoothing of ABS and ASA 3D prints hasn't been a science. However, I'm working on making it one since I'm not a fan of eyeballing stuff. I'd rather calculate parameters to get consistently good results. I'm experimenting with a process that consists of a warm acetone vapor bath...

I FINALLY got the mounting plate to print without warping. It seems Polymaker ASA may leave a residue on the print bed that affects adhesion, unlike the eSun ABS I use. I had to wash the bed with dish soap to solve the adhesion problem. The blank is functionally done! I have some...

I printed the box! It's my first time printing with ASA. Now I just need the mounting plate to stop warping... I'm thinking about acetone-smoothing it to reduce the visibility of the layer lines.

Of course I found this after buying my first roll of ASA ever! :LOL:

You'll want to flip the hubs and run the super singles dish-out. Your rear axle bearings will thank you if you carry any meaningful loads in the back.

Is there any concern about the torque rod overcoming the washer? I take it there isn't since the Canadian Army has done it just fine. It probably doesn't help that I don't have a clear understanding of how the rods work and what the rubber bushing is supposed to do.

How were those done? Were the dogbones removed and put on the drill press? Or just a steady hand with a big drill? :p

See my comments in green. Thank you for your insight :tank:

I think I've got it now. Those measurements for the stickers and fillets really helped, thank you @Crapgame :) This is a blank, so anyone who wants a box can drill their own mounting holes as well as holes for switches, buttons, whatever is desired! I do have pilot holes designed so that...

Does your gauge cluster have panel lights? That parking brake light went where one of the panel lights is supposed to go.

The trucks with dual-circuit brakes have an indicator installed in the middle of the gauge cluster that shows whether the parking brake is engaged. It also lights up when a circuit loses hydraulic pressure! I think it would be a neat idea to install such a light on the dashboard somewhere to...

This is extremely helpful, thank you!

Wow that axle was bent! But considering it's a 2 1/2-ton dump, I imagine it was something about overloading that would've caused that damage? I was hoping the axle itself would be bent back, not just replaced :p Still a neat video!

I wonder how many M135/M34 beds are around! If one isn't going for historical accuracy, I'd go for an M35 bed since it's completely flat across the floor - no wheel wells to worry about :) I take it that they're more common too.

Most deuces will have a single-circuit system. Some built in the 80s came from the factory with dual-circuit brakes. Maybe some in the military were retrofitted as evidenced by the document I referred to. All M44A3 trucks came with dual-circuit brakes from the factory. The bottom line is...

I read this post and was wondering how this works for dual-circuit systems: Based on this diagram from page 1-4 of SMI 9-2320-209-14&P, both air packs run the trailer service brake connection, so the trailer will still get some kind of air signal if a brake circuit fails. I wonder, though...

A friend of mine has a HMMWV he built with reproduction smoke grenade launchers on it, and he had a control box from which he gave me overall measurements. I think I have this pretty close now: Overall dimensions including mounting plate are 4.25" L x 2" W x 3.25" H. The bump-out for the...

What are you using for modeling? I've been using primarily Autodesk Fusion 360 as I am most familiar with Autodesk products due to my career.

@oddshot thanks for bringing this thread back to life - it was a good read! But now I'm wondering: Are there any patterns published for the tops? How about seat covers?
