19th April 2008 - Fin Structure

Installed and final-welded the fin spar, fin leading edge, top-piece and braces. The bottom of the fin is offset 1/2" to the left to counteract engine torque but the top piece is in line with the fuselage. This takes a little time to set up and brace before tack welding but the end product seems accurate. Next it's the rear left and right fuselage side diagonal cross members and the fin bottom profile tubing which lies on top of the main fuiselage structure. The fin ribs are made from thin and soft U-channel so these will wait to avoid damage while the rest of the fuselage structure continues.
