I'll have to inventory all my stuff from before, but I think I already have most of the items you suggested. One thing I really need to add to my workshop is an el-cheapo drill press. Makes drilling holes straight so much easier. When drilling a motor mount, for instance, it's difficult to get the holes exactly straight and if I'm not careful I'll end up with a crooked bolt or two which tends to bind the motor somewhat. It works, but I'm really tired of not having perfectly straight bolts holding the engine on.

Another thing I really want is a good pair of calipers. There are times I need to check the thickness of a sheet or strip of balsa. I have the triangle set, but I still kinda get messed up at times. Calipers would help that so much, and they're not that expensive.

And clamps! I can never have too many clamps. Maybe small bags of sand or shot to use as weights for sheeting.

Otherwise, I think I pretty well have most of what I need stored in the piles of stuff in the garage. I just have to work my way to the area and inventory what's still there, what needs to be replaced, and what needs to be purchased.
