Bill, #1. Bolt was tight, but going in, not getting tougher as I went, as happens if you have the wrong pitch, and then when almost home broke just below the surface...
It's strange I chased the other three posts and they seemed rather clean. I had made a little jig and got the hole drilled for the ez-out with a left-handed drill beautifully centered. The ez-out had a good bite and I'm turning little by little waiting for the screw to start turning and pop the ez-out breaks absolutely flush with the surface of the bolt. I had chosen the smaller of two ez-outs hoping that it would not cause the bolt to further bind up. In hindsight with the pilot hole centered in the bolt i should have keep using bigger drills till I was at the minor diameter of the thread, and picked out the pieces. There are just so many lessons here. Joe On Mon, Mar 21, 2016 at 1:02 PM, Bill Lindsay <tapebu...@gmail.com> wrote: > There are four different ways I've broken bolts in the past. > > 1.
