A real landmark day to day - horizontal and vertical stabilizers attached to the fuselage. MUCH easier than I had anticipated, mainly due to having the use of a laser level, which made leveling the fuselage and the subsequent checking of installation really easy.
Got a few queries tho.
1. The F-812B-1 angle/control stop - it has 3 #30 holes in the vertical surface and5 #30 holes in the horizontal surface - so how many bolts should I put in - the drawings look like it's two in each surface??
2. We marked out and drilled the three holes through the vertical stab rear spar/F-812-1 bulkhead and WD-409 tail spring mount ( a real pain - eventually we used the laser again and made a small template to mark out the hole locations). Final drilled #12, as the instructions specified - and then realized that the drawings call for AN4 bolts - which clearly aren't going to fit! Everything else on the tail assembly is AN3 and the drawing for the RV8A shows 4 AN3 bolts in this location - so do we drill some more or use the AN3 bolts??
3. We got the three rudder hinge points aligned pretty easily but the trailing edge of the VS is not absolutely vertical - it is slightly raked aft by about 3/8 inch. The instructions don't seem to specify that it should be vertical - is this a problem?
If I can get my camera to work I'll put some pictures up.
Many thanks for help/advice.
