January 11, 2009 - It doesn't look like much after all that work.
Still, here's the first corner of the new frame. When I look at it in the car, I realize how short many of these distances really are. Most of the length of this bar will be welded to the bottom of the car, both to the floorboard and tied into the existing frame rail. It's not going to be difficult to make everything stiff and solid. I spent most of my working time today finishing some of the design work in my head, and I'm pretty happy with it all. This is just a skeleton.
You can barely see it in the picture, but the upright is welded to the front suspension pickup. I'll add in an extra triangle to help spread the forces around as well as tie into the crossmember that will support the steering rack. The upper end will be tied into the top of the fender and the beam in there, as well as back to the firewall on a bit of an angle. I'm also planning a little more bracing to tie the upper control arm mount to the upright a bit more - nothing complex.
The one mistake I made was that I didn't cap off the end of the upright, and it's going to be tough to do now. I don't really want to leave it open to the elements either. Whoops. It's possible to do, but it will be awkward. Then again, there's no chance of water getting trapped in there now! Is it better to make it watertight (hopefully!) or to make it irrelevant if water gets inside?
