Nice work Jim!

Glad to see you decided to go with the front dowel approach - much cleaner and easier to just mount two bolts than 3 or 4. While it probably isn't required, it wouldn't hurt, for a little additional insurance to add a 1/8" ply doubler to the front of the former where the dowels go in. The laminate of the two pieces of ply, provides that extra bit of strength. I'd also add two pieces of 3/8" tristock on the side where the ply bonds to the fuse sides. Weight gain will be marginal. Some builders also like to encase their 1/4" hardwood dowels in aluminum tubes, this keeps the diameter constant and prevents them wearing down with fuel, elements over time. A nicer alternative, I think, is to use bamboo dowels - that stuff is rock solid and will last an eternity. Some Japanese kits used to come with bamboo.

One other suggestion would be to apply a second layer of glass (you're looking for 1.5 to 2 oz cloth) out to the edge of the wells. This should be roughly 6-8" wide if I recall correctly. This is structural glass since the wing joint has no strength other than for this glassing unlike other pattern wings which sometimes use flat cross panel full height spars. When you apply your finishing glass over the entire wing, that is really for paint prep and it doesn't contribute a great deal of strength to the joint although it does make the wing that much stiffer overall.

I look forward to seeing a frame up of the model - some bench flying is important! [8D]
