Firewall Project

pro70z28 · 05-11-2010, 07:51 AM

Forgot I took some shots of the process when I stamped the shallower inlet side.

I cut the 3/4" MDF out on the CNC. I gave one side 1/8" clearance for the metal and the other side the circle press fit into the MDF.

This made the die the right depth (I needed it to be stamped 1/2" deep for the right offset). It also made it easy to register the die halves.

Once out of the press all I had to do was hammer the tucks and it's ready to trim to the firewall. The firewall that doesn't exist yet.

Got a little more done on the firewall this weekend between honey -do projects.

I made a hammer form out of a 2x4 on the band saw to match the contour of the firewall and beat some metal into submission. Still needs a little hammering but it's close enough for a test fit.

I decided to do recessed panels on the sides & I think I'll do raised panels on the front, but I've changes my mind so many times already, who knows.

This part of the firewall will get welded to the body. The rest will get welded to the chassis and the 2 will be bolted or riveted together (blind seam) from the inside

I think I spent more time in the lawn chair thinkin' about this than actually working on it. I kept changing the plans until I had a headache & finally decided to just do something. If it doesn't work I'll start over. I want to be able to take the body off, so that's why it's going to be a 2 pc. deal. Sort of the same reason I spent all that time on the billet aluminum hinges rather than just welding them to the chassis. Keeping the "A" pillars I'll still be able to use stock door weatherstripping and boxing in the firewall under the windshield I'll be able to keep the stock windshield wipers, got to keep it street legal right?

Got a little more done on the firewall this weekend, Welded a few of the small pieces to some of the medium sized pieces.
