ATS Spindle Thread Split

[baz67]

I guess I should not have said messing. I was thinking more in a street form and the taller spindle and Guldstand mod may be too aggressive for a street driven car. Once again that chicane67 guy explains what I want to say better than I do.

That is indeed an SLS DuraformGF (glass filled) rapid prototype. If you go to quickparts.com they have a lot of information for material specs and tolerances for each of the different processes. You can also get an instant quote with an STL file for all the different operations. We made all the machine operations undersized so that we could machine it ourselves with better accuracy. And yes rapid prototyping rocks! I pulled this information from their site....

SLS Highlights:
Ideal for durable, functional parts with a variety of applications. Capable of producing snap fits and living hinges.
Maximum dimension for instant quote: 11”x13”x17”
SLS Material choices include Duraform, DuraformGF and Somos 201.
Standard Tolerances of +/- 0.005" for the first inch, and +/- 0.002" for each additional inch for Duraform and DuraformGF. For Somos 201, tolerances are +/- 0.04" for the first inch, and +/- 0.002" for each additional inch.
In the z height (vertical), standard tolerances of +/- 0.01" for the first inch, +/- 0.002” on every inch thereafter.
Standard Resolution: 0.004”

Where do I sign up for a set of these things!? Is it first come first serve when they become available?

Excellent, thanks. Yah SLS is real strong, Ive only done FDM here and its fairly strong, I think SLS is the most if not one of the most accurate prototyping methods. We use a program here to estimate build time and cost. luckily my school has the FDM machine and im not paying out my rear end for each prototype i make.

and again thanks for the info.

Wow,there`s a LOT of disjointed tech flying around here! There are no magic bullets,geometry is geometry. The 1.4" taller 7/8" drop spindles yield some very good numbers. I ran it with 1" drop springs also for a 1 7/8" total drop. Nice RC height (around 3" depending on several variables), pretty stable laterally (not great but good). Camber gain is mild,roughly -.5/in. *average*. Adding the G mod is not a good thing, it raises the RC too much,and shortens the FVSA dramatically although the camber gain gets pretty juicy (around -.85/in *average*). The numbers on the tall spindle with SC&C tall UBJs are better. RC height about 4" (you really don`t want to go any higher than that as a rule) with about 30% less lateral migration. Camber gain avg. about -.75/in. FVSA is a little short at about 95" but should work fine.
About UCAs. In stock form the UCAs droop,they`re low in their curve. Raising them moves them outward increasing + camber until you reach the apex of their curve,then it goes -. Raise them far enough past their apex to get back where you started and the UBJ will be in bind at ride height because the UCA was designed to keep it level when the UCA was drooping (in stock form). That`s why doing the B spindle swap on A and G bodys practically requires a shorter UCA. I say practically because people will hack just about anything together and drive it. ATS tall spindles will also require a shorter UCA IF you want full alignment range (especially on the - camber side) and full range of travel without UBJ stud bind. It`s not a shortcoming or flaw,just simple geometry.

This looks like a very good design. Taylor,will you be taking on dealers any time soon? I`d be interested in marketing them bundled with application specific adj. tubular UCAs with the tall modular UBJs as an option. Marcus SC&C
