Hello all, Well... I'm through with those ultralight Cub wings and have started back on my Fly Baby's biplane wings. Look at all of those nose ribs to cut out!! Well. I have made 2 patterns for the nose ribs out of some left-over Lowes 3/4" Oak Ply One for the main rib which is notched for the capstrip and one for the false ribs. These are shaped like a "c" or horseshoe and has very little to hold to when running it thru- the router. so... I mounted the pattern on a piece of plexiglass. makes it easy to view what's happening underneath and large enough to hold on to. It also disperses the wood chips out to the sides and not in infinate directions, face ears, hair etc. I used a 3/8" Fluted laminate trim bit with the ball bearing as instructed by Steve at Replicraft. Whom, may I add, builds beautiful Piets! I have decided to cover the leading edge "D" with plywood. The sheet metal type is easily dented. 1MM FINNISH BIRCH. or 1/16" BASSWOOD (any other Suggestions?) I have recently finished building a pair of wing kits for a J-3 Kitten that used .8 MM Finnish Birch ply to wrap the leading edge. As I was looking in the ACSP catalog under Plywood I see that they have the Finnish Birch in a length of only 60" when they have it..... They also have the Basswood Aircraft Ply in the regular 4'X8' sheet. My question is... can the Basswood ply be used as the leading edge wrap and still have the strength as the Birch aftre being saturated with the Epoxy Spar Varnish? What do y'all think?? well.....that's all for now Whos going to Lakeland next year??? "Steze" http://community.webtv.net/smlangford/StevesFlyBaby
