Brief Description: Received Spars back from Machine Shop
Excellent Job ! The machine shop charged me $90 to drill the 12 precision holes for the AN-6 bolts. Well worth the $ and the peace of mind. I had to order AN6-16 size bolts since the grip length on the -15 was not quite long enough.

Compare the far right bolt (AN6-15) to the -16 (center and left)
