Brief Description:  Engine Mount - part 2

So once the jig is ready, you cut and fishmouth the steel members to sit up against the 4 'spools' that actually attach to the firewall (Image 1). Also visible in the preceeding description (part 1) is the 'tray' I purchased from William Wynne, which is arguably one of the toughest pieces to make. Anyway, after lots of trial and error, and a lot of deliberation, I finally elected to have this critical welding done by Aircraft Welding in Hartford, and boy was I happy I did. Beatiful TIG welds are clearly evident in Image 1, and those were supposed to be tack welds. Whatever this lady did was pretty impressive, because there was very little warpage when she was done, and it still fit the firewall just fine.
So I used that opportunity to build a metal jig (as William Wynne has) so future builders wanting to put corvairs on their rebels can do so with a lot less trouble than I (Image 2). Then I took the mount back to Aircraft Welding in Hartford for final weld-up and you can see the finished product in Image 3. It was a long road, and to be honest, I won't really know how well I calculated everything until the entire firewall is complete, but I'm fairly confident I'm in the ball-park. Again, if the plane is a little heavy in front I don't mind, since I have the BRS chute permanently installed behind the pilot (50 lbs) that needs to be counter-weighted.

I can certainly see why engine mounts typically run $1000...they are 100% worth that money. If you can avoid building your own, do so! Onward and upward...
