Titanium Firewall

Postby Tralika » Sun Sep 04, 2016 9:14 pm

I fitted the stainless steel firewall that came with my kit prior to covering my plane. In the mean time I saw a titanium firewall that F. Atlee Dodge makes for Cubs. I did some checking and found out that McMaster-Carr has .020 titanium in 24 X 36 sheets for about $150. I spoke to the folks at Atlee Dodge and found out that they use .025 Titanium but they said that .020 was fine for a firewall. According to them, material as thin as .018 is acceptable on certified aircraft. I bought a sheet of titanium from McMaster and just finished fitting it. It is almost 4 pounds lighter than the stainless firewall (3 pounds 12 ounces to be exact). I haven't finished the last cut to fit the top of the firewall to the bottom of the boot cowl so it I may save a few more ounces when I'm done.

So that comes close to $40 a pound. Not cheap but worth it to me. The photo shows the titanium firewall mounted on the plane and the stainless firewall on the floor.
