My plan is to put some sealed nutplates around the perimeter and down the center of the shield.

Also, .010 stainless sheet is on McMaster: https://www.mcmaster.com/#standard-shims/=15vvzw3

Will a 24" x 50" sheet work for the firewall and belly shield of an RV-7?

Default Firewall Recess Area

Anyone have any photos there willing to share on how they covered inside the firewall recess neatly using the Fiberfrax and SS foil. I've done a sample with cardboard and don't care for the look.
Any thoughts or reasons why you cant just cover the recess for a simpler install especially if you have a right angle oil filter adapter? I don't have any penetrations coming thru it now.

I'd be very interested in knowing this one as well. If I can leave the recess off entirely and just use a flat cover on the opening I'd prefer to do that.

What goes into that space in a normal installation?

Besides the "end-on" oil filter already mentioned, my understanding is the recess accommodates a constant-speed propeller governor mounted to the accessory case.

Default Bingo!

Yes. Here's the recess on the RV-3B I'm building.

So basically there's no reason the recess cant be covered if your not intending to use a constant speed prop and you have a right angle adapter for the oil filter? Alternators mounted on the accessory case should not be a factor because of the location right? I'm going from an auto engine to a Lycoming so I am eyeballing locations before I insulate the firewall and hang the engine.

Still would love to see pics of someones insulting job in and around the firewall recess.

Hmm. I'm planning on a remote oil filter but the governor may cause a problem.

Are parallel-valve O-360 family engines with forward-mounted governors common?
