I'll throw a couple pics in here--the rest is in my build thread (1963 Falcon), I think. My whole interior is all 20 gauge, short of the plate where my masters bolt up. My firewalls (front and rear) and the tunnel have tubing structure (mostly .095, some .065, a few .120, depending on location/load potential), so there are no unsupported spans of sheet anywhere. I even made my last version of wheel tub extensions out of 20 gauge; the more it's welded and formed, the more rigid it gets. I (spot/tack) welded the snot out of the interior panels to whatever tubes were available--I took logic from modern car structure, as they advertise these days how the frequency of welds in unibody structures increases stiffness overall, kind of like racers have been doing forever. The car is still lighter than the C4 Corvette it once was.

Thanks for your input.

Welcome to the site! Looks like a killer build. Keep us posted. I love seeing this stuff come together.

Got it rust, you are talkin steel, I'm using aluminum. Not sure if it actually will be lighter in the end. I'm already thinking I should have done what you did. After comparing the weight of a square of 16ga al to that of 20ga steel plus the weight of the steel flange I need to rivet the aluminum to plus the rivets probably not much gain. Guess I'll rest easy knowing if my car sucks I can power park and polish my aluminum!!!

Cool build...I'm tuned in.

I've found a few nights and rainy days to work on things the last couple of weeks. The frame has gotten an annoying amount of surface rust and I am feeling good enough about the design to finish weld most of it. So decided to strip it down and get it ready for paint. There will be a lot that gets ground back off for future fabrication but will also allow me to permanently attach stuff like firewall, roof, floors. Still need to do a better job of supporting the quarters and leave room for a fuel tank.https://lateral-g.net/forums/attachme...1&d=1522106247

Had an x-frame between the a pillars. That was the most efficient use of tubing and low COG. It also was very close to the scatter shield making future engine removal tough. Also was going to interfere with toe room and pedals. The truss will make this all a lot simpler so....https://lateral-g.net/forums/attachme...1&d=1522107308


Pulled the engine out last night

Now if you could only find who made that invisible paneling for Wonder Woman's jet . . .

cool build Scratch!

This is going to be kind of a lame update because it's been a long day but here is the progress. I started building the cowl and have been working back from there. So far I am fairly happy with the way the firewall and toe boards turned out but the man hours are excruciating. I got most of the bare metal primered and the inside of the roof and the roll cage that will be inaccessible is painted.

Great build! looking forward to seeing this come together. Nice job
