Mike; I used the stock method on my Scout meaning the wooden version. I did notuse any attachment to the ribs other than T-88 glue (no nails or otherfussing). It made a nice clean item to cover. On another plane with the samestyle ribs, I used the aluminum pre-formed trailing edge. That was quickerbut more of a pain to attach using small screws and epoxy plus epoxy fillersto smooth things out. On any subsequent planes, I am going to stick to thewooden trailing edges. Set up the table saw, practice a bit then go slow andwatch what you are doing and DO use a fine cut Carbide tooth blade. Only usespruce as the wood will want to warp after it is cut, spruce being the leastlikely to warp as much. I have tried several other woods which will work butthe spruce doesn't warp like the others (moisture content).I did the same with the leading edge. I used two pieces laminated to makethe nominal block (to cut down on warpage) then made four cuts that cameclose to the final profile on the above table saw. After attachment to thewing, I used a cardboard profil to check my progress after using a 3" beltsander to sand to final shape. Again, I only used T-88 epoxy as the onlyattach method, I didn't use all those screws as on the plans. Remember, theydidn't have the epoxys of today to use as we do. That is why many old planesbacked up critical glue joints with fasteners as in the trailing edges. Iron Mike Cuy (his real name) used a wood stair railing purchased at alumberyard that was VERY close to the actual profile of the leading edge forhis leading edge. Only problem is people at airshows just have to walk alongthe front of the wing sliding their hands along the leading edge for somereason.........Earl Myers-----Original Message-----
