Does anyone have a set of plans or pattern I can follow to make a new wood (probably plywood) firewall for the 1920 Depot Hack I'm building on a 1920 frame? THANKS!
You can get a new wood firewall for under $90. Are you sure you want to go to all the trouble of making one? By the time you get a patter, the wood, and whatever else you need you could have had one shipped.
My $.02 worth....
I second that. But if you have a low steel firewall you can use that as a pattern and guide.
