The final item for the F705 bulkhead was to drill the 2 flap blocks that will get bolted to each side of the bulkhead. I measured where the 1st #10 hole should go for each block and then drilled them on the drill press. I wanted to make sure the holes were drill straight through the plastic blocks. Then I bolted each block to the bulkhead and used the #10 bit in my pneumatic drill to start 2nd holes. I then finished these holes off in the drill press to make sure they were also drilled perpendicular through the thick plastic. The plastic blocks were then deburred so to speak and then stored back in one of my parts drawers. They can't be bolted permanently to the bulkhead at this point or they would get in the way of riveting the skins to the bulkhead. The F705 bulkhead is done for now!
