I'm about to hang my engine. The fuse is supported on a stand that is under the wing spar box. It's 5.5" wide, so it hits both the front and back of the main spar box, and it runs the full width of the fuse. It is covered with white insulation foam, the really soft stuff, which if memory serves, has about a 7psi crush strength (blue foam having ~15psi).
I figure there's going to be roughly 600 lbs, with fuse, panel, engine, prop, cowl . . .you get the idea. Add me and tools it gets to 800. The foam will take the load(with something like 200 sq in of bearing area), but I'd really not want to bend skin the spar box area. The foam will distribute some of the load.
Anybody done anything similar or have thoughts?
