ran down to the yard store and picked up some appropriate size stubby bits for my 90* drill. Finished drilling the fwd h/s spar without issue. Slid a couple of 3/16 drill bits under the aft spar to act as a spacer per instructions, but then I ran into a surprise. The build instructions then tell you to measure from the tooling holes on the inbd ribs to make sure the chord of the h/s is parallel to teh aft deck, i.e. 0* angle of incidence. I just about have myself a heart attack when I tried that and discovered teh aft tooling holes on H-00005 were at least 3/16 lower than the fwd ones. Once I got over my panic, I looked at it closely and discovered taht hose holes aren't in the center of the web. There's no way that measuring from them will tell you anything. Took pictures and sent to Vans for clarification, then applied a second coat of epoxy to the tailwheel hardware. I also took the opportunity to finish priming the outside of the F-790 pushrod
