Match drilled the right and left lower and upper spar caps to the vertical satbilizer spar without any problems. There is a lot of match drilling to do here. The first picture shows one upper and lower spar cap drilled the other not yet match drilled. The second picture shows all 4 spar caps match drilled and deburred. Countersinking of the upper spar bracket was completed next. The third picture shows the countersinking of the holes in the upper spar cap. Because 2 of the holes are VERY close to the spar cap bend radius, you are not able to use the microstop countersink. I placed the countersink bit in the drill press and countersunk the 2 holes very slowly to the correct depth. Countersunk the required holes in the main spar and the front spar with the microstop cutter.
