Before you drill out your RV-7 firewall engine mounts!

[N702PL]

Being an engineer I came up with a simple idea for all of you about to drill out your firewall holes which will match your engine mount EXACTLY!

Please check out my easy method of location exact hole centers with a simple tool I came up with after buggering up one of my holes the night before. I'm still mad at myself for that one, but I was really tired and I should have stopped long before I picked up my unibit and reamer.

I hope this helps someone! It sure made my life a lot easier today and no curse words were uttered!

Made me laugh

Cus I made the same mistake and used the same solution to get it right after I removed the lower mount and welded a plate over the hole!
