Projects Firewall question..

Hello, I Would like your Experienced thoughts on what GUAGE of Steel should be used for a RECESSED Firewall. 14 , 16 , 18 thickness ?? What would you use? and How have you made yours?

Thanks ..

 

I,m using 18 gauge.

 

Firewall should be a minimum of at least 18, no lighter since it helps strengthen and deaden sound as act as a barrier agianst engine heat, noise, fire(should things get exciting).
Me, I'm into the math thing, I'll layout pie cuts and heat marks, whup out my plasma and rosebud and go to town,
then I finish up with a little teasing with a 5 lb. drilling hammer, some tnder loving care with the deadblow,
and finally the romantic stuff with the dollies and a english wheel or planishing hammer.....whichever the mood calls for!

 

The ol' tin wheelbarrow trick still works!

 

Here is how I built mine. Says 10ga but its actually 12..... I shouldve used thinner material and deffinitly would not have hesitated to use 16-18 if I had a beadroller at the time.

I used 16 gauge on my '30' coupe. More difficult to bend, but very sturdy and easy to weld.

 

Mine is 16 Ga. Recessed 2"

 

I used 18 gauge for my firewall. I had 16 gauge but opted for the 18 gauge for ease of cutting/bending.

 

I used 18 ga. for mine. Here is the tech:
