Brief Description:	Tail drive couplers
The bolts that secure the drive coupling to the main trans and the tail rotor gearbox were a little close to the radius causing the washer and or bolt head to tighten down at an angle. I clamped the couplings in the mill lining up the holes with a drill bit chucked in the mill then switched to a .500 end mill and created a flat area for the bolt/nut to tighten down against.
