				| Time to start working on the seat backs
 Here I'm drilling the lightning holes into the F-638 back brace. I've had this drill bit ever since high school. Who would have thought that I'd be using it to build an airplane! I set the drill press on the slowest speed and went really sloooooowww on these holes. You don't want to be holding a piece of sharp-edged sheet metal and have the thing spin out of control by going to fast or pressing to hard.
