I’d love to see the catch for the folding Westy table reproduced. Unless it’s already available somewhere and I just haven’t seen it. I’d say 9/10 I see are cracked and broken. I’m not sure if the flex it needs to have would be an issue?

Hey dudes,

I would like to work with someone who has design and 3d printing abilities to make a torsion leaf assembly jig.

See the outline of the torsion leaf assembly here?

I think a small donut with the internal cutout of that leaf profile would be Most Excellent when installing torsion leaves into the front beam. I was messing around with zip ties and torsion arms today trying to get new leaves into my old beam, and a jig with that outline would have saved me a few hours of work.

Willing to pay…
Robbie

Seems maybe you could fab such a thing from sheet Lexan as a one off pretty easy. Ray is our materials scientist, he would know if it would stand up to the grease.

It doesn't matter if it stands up to the grease. Once the leaves are installed, they're secured to the beam and secured in the torsion arms. No amount of soft plastic will affect the suspension one way or the other. I want this part 3d printed because I know most of the raw materials that go into cheap printing will flex enough to be ignored once they're trapped in the torsion tubes.

I have six zip ties in my beam as we speak… Cool The picture below is one of nineteen failed installation attempts due to misalignment…

Gotcha. I was thinking it would be removed, not trapped. Makes sense. Cheap, but not too cheap is the aim I guess. Great idea. I still think you could fab them from sheet lexan with a scroll saw pretty quickly. Or mold them from polyethylene maybe.

Seems simple enough. I'm taking a 3D printing CE class and need a project. Got some measurements of what you want?

the part need to be modeled first in a 3d software thats the more difficult part, i 3d print professionally. i wonder if this woudnt be better off as a cast metal part though? it could be made in aluminum easily, but again the part woudl need to have tooling made to produce it.

Correct me if I am wrong but would it not be easier and more precise to have that part C&Ced?

You guys are missing it. He wants something that is cheap and can be left on the springs after assembly. The springs would need to be able to move freely once installed and under the stress of the vehicle, so no aluminum allowed, sorry. This also means that the jig doesn't have to be super precise either, if the material is a little flexible that's almost ideal, make it a little tight to hold the springs well during install then the springs can rip through it under compression later. Their soul purpose is to hold the springs together during install. Id think a 1" thick 3d printed cube with that cutout could work ideal. One on each end of the spring pack. It's just making sure the elasticity of the block is correct. It should have a little movement (maybe a mil to allow for a tight fit) then shear after that in order to make sure the spring rate is not effected once the front suspension has returned to service.

Exactly! I would like it to be flexible enough to not impact the leaf springs in any way. Plus, they have to be expendable. Two or four would be needed for every leaf pack installation, depending on the condition of the existing leaves. They would also have to be small enough to slip through the bronze/plastic bushing assemblies that sit about 6" inside the beam tubes. A hefty zip tie is BARELY small enough to fit by, when zipped around the leaves.

So I think the 3d-printed tool would be perfect, and I'll try my hands on creating a model some time this week.

ahh i totally missed that , yeah definitely no aluminum for sure! these can be printed with a thin shell to so they disintegrate after install, hmm cool idea!!

Looks like it would take about 15 minutes to model with the dimensions. I'd be interested in helping out as I can see this being something I may need while rebuilding my beam. Depending on the thickness they could be printed relatively quickly.

I wanted to note for future reference, that I use a company called Shapeways
https://www.shapeways.com/ to outsource some 3D printing that my machine is too small for.

The cool thing about them, you can upload your model and choose your material. They can print in steel, aluminum, plated metals, plastic, sandstone, etc. which really opens the door to using 3D printing for automotive applications.

Pm sent to Asia3b.... and

If someone sends (or posts) the dimensions, I can model and 3D print this pretty easily. We could pop out a dozen or more so someone who wants one could get one (or four).

it is a lot easier to put the torsion arm back on if both front wheels are off the ground. I've never had a problem sliding the arm back on that way.
