Today I did a little more on my aircraft project. Cut some pieces for the fuselage skin and glued the aft section of the fuselage in place. On some places the plans call for "scarf" joints. These are overlapping lines of plywood. The forward section of the bottom skin is a 1/8 inch thick piece of plywood over a 1/16 inch thick piece of plywood. Trimming a 1/6 inch off the thickness of a 1/8th inch thick has it's own challenges. Once again I went to the plans to see if cutting this large piece of 1/8 ply (22" x 58") would impact later cuts. My surprise was that this large piece is not in the cutting plan! Fortunately I bought an extra 1/8" 4'x8' sheet. Last week I put two stainless steel machine screws, lock washers and bolts on the lower polymer rudder bearing. No bolts are called for in the plans but the plans identify "epoxy" the polymer bearings in place. After a few tests I found that epoxy does not stick to polymer. Other VP1 builders identify bolts or screws to keep this from shifting. There is no load on the bearing bolts.
