SPRINT 4 TWO.. 5-21-24.. drill holes..

drill bits, marked 29/64, werent same size. first 5 on one hub, not much meat left for the tap. second hub, used smaller bit and got normal meat left for the 1/2x20 threads. wont matter since they bottom out on the back side. getting the tap straight, takes some doin by hand, to get it started. drill press didnt work as planned, like everything else i do..
