Good interpretation.

And you know what. I've got the sucker rebuilt. Actually, the epoxy is curing as we speak. I'll have the cowl on this evening. And guess what I'm going to do. Weigh the sucker. And we'll know how much weight it gained.

BTW, I replaced the firewall with a sandwich of plywood much like the original. The original was two pieces of ~3mm liteply glued together. My repair uses one piece of liteply sandwiched with a piece of 5-ply Aircraft Plywood. Since my two plywoods gave exactly the same thickness as the original, I decided to put 5-ply "pads" on the backside, to protect the liteply from crushing by the T-nuts. The main problem with using liteply in this situation (with T-bolts holding on a motor mount with a compact foot print) is that the liteply stands up to the compression poorly. Five-ply doesn't crush nearly as easily as liteply when compressed. Liteply could crush during installation, but who'd be able to tell? And the compression could be slight enough that it didn't obviously damage the veneer, yet degrade the integrity of the firewall enough that it'd fail later. Heck, liteply might fail from flight loads if you really hossed the airplane around. Heck, you wouldn't even need to hoss it. Just do some snaps.
