The well centered hole I have drilled out to 3/8" almost to the edge of the block threads. I have tried to get a tap started, but not enough threads available yet to get it going.
Any suggestions for how to remove the remaining stud material? Drill out more to enable the 1/2"-13 tap to work? Drill out the holes enough to use some sort of thread insert?
Heat, lots of heat with the easy out.
