WTB: some aluminum parts machined for custom shock mounts

[Turbo67camaro]

I'm looking to get 2 parts made, quantity 2 each, for a total of 4 parts, made out of, or cut to 3/4" aluminum.

Piece 1, need quantity 2, all the angles are 90 degree angles. After some mockup, I'll be drilling some additional mounting holes, but I can handle that.
55792

Piece 2, need quantity 2. This has two 88 degree angles, giving this spacer a total 4 degree taper:
55795

PM me please if you can make these and the approximate cost.

I'll be using them to move my rear shocks inward on a G-Bar 4-link, in conjunction with the double shear shock mounts that Alston uses on the G-link system. So, the aluminum stock needs to be strong enough for that type of application.

I could build those in my garage with a bandsaw, drill press and 12" disc sander. If no one else wants to help I can do it.

I would use 6061-T6 aluminum. Any metal supply should have a block of scrap.

As a design engineer I like 2D drawings over model based definition like you have there. Any tolerances? Super tight tolerances will drive the cost up with a normal machine shop. Typical tolerances are +/-.030" and on +/-2* degrees.

Hi Bryce,

I just went looking for aluminum stock, and ran across this place that will supply the 6061-T6 material with most of all the cuts done :). Simply amazing the stuff you can get online now.

So, all I'll need are some holes drill pressed, and the 2 degree taper cut into two sides of the smaller pieces.

The .030" tolerance sounds fine, but the +/- 2 degrees on the taper seems more tolerance than I'm looking for. A margin of error of 2 degrees could leave it at a 90 degree right angle with no taper. On second thought, I just realized I need to finalize my pinion angle which could increase or decrease my desired 4 degrees of total taper. I'm trying to eliminate a difference in angles between the shock axle mounts, and the angle that the rear coil-overs hang down when in the middle of their bushing side to side travel.

I'm ordering the cut stock now. I'll post an update once I get my pinion angle finalized.

Thanks,

Mike

If you still need the parts machined I have access to a full machine shop with CNC and manual machines. I can even do it on the side for a few bucks. If you still want it done.
