So, you guys drilled the engine mount bolt holes in the firewall......
yeah I was wondering the same thing....not having the engine mount in hand yet wasn't too keen on drilling those holes?????
Rick, I appreciate your input on this thread. I am making the same kind of rotisserie for my RV-7A. I am almost ready to drill the holes through the firewall and I do not have an engine mount. So a couple quick questions. I plan to drill them #12 for AN3 at this point and will enlarge later.
Is there any angle thru the firewall that is important to the mount? Or can I drill them straight thru, perpendicular to the stainless firewall, for now?
And also, do you drill them thru the existing holes in the stainless firewall that Van's put there? Is this the right location?
And so later when I drill the "real" engine mount holes the location, size and angle will all get fixed if I drill a straight thru hole now with a #12 size bit centered on the existing holes on the stainless firewall?
much appreciated.
