Joe - here's what it will look like....

While there's a bunch of fab going on, I think what Karl's pointing at is that there seems to be a lack of engineering supporting it - at least on the chassis/suspension side. Wicked camber curves though...
 
I see what you mean. That puts it into perspective. Seems weird to have the lower pivot mount so far under the car, I'm assuming that's to add for more travel?

Some of that went over my head, but I know you know your ****. So.. yes I agree. :nod::omg:

LOL Do you guys know if this guy has had the same kind of training/schooling as you guys?

Don't assume I know anything. I go to school (poorly) for Electrical Engineering, so I'm as self-taught as anyone else here. M. H. Yount hit it on the head though. There's generally nothing wrong with seat-of-the-pants building, but unless you decide scrutinize your designs with at least a modicum of engineering best-practice, you're going to be leaving a whole hell of a lot on the table.

You mean the piece of square tubing bolted between the control arm and upper damper mount? It's just a damper placeholder.

What bothers me is how almost everything is thick plate steel or just grossly overbuilt, rod ends in bending, load paths that are poorly accounted for, camber adjustment that changes SAI, and the practically nonexistent kinematic simulation.

I was thinking that too after seeing all those pictures, nicely done but crude engineering, Like a big go-kart more than a race car, But, still nice work. I'm like that I'd rather do it myself even if its not as high tech or leading edge, as long as i did it, just not on that scale.

I suspect part of it may be it's an industrial machine shop and he sees the production of structural weldments through that lense. They probably make stuff for sawmills or something.

The designs are typical of heavy machinery, basically. The MO is use steel and overbuild until infinite fatigue life is guaranteed and call it a day. Part of the absence of aluminum.

He says they build hydro turbines, might explain his avoidance of reciprocating parts.
 
Hi guys! I found that you have a thread about my car I didn't know about.
Would you like me to update it here as well?
