Thanks for Pointing that out Kelly, Good info here, Personally I have only run accross a couple broke off flush, altough seems like I turned a few away before I was willing to try. I guess I was'nt causing enough friction when I drilled to heat it up, so I noticed no glue melt down during drilling. I suppose I was worried about tightening the pin up more & splitting something, or heating the joint up too much, so I took It slow and easy with forward drilling, and after heating, reverse with something that I used as an easy-out (not sure that's what it was because I did'nt have a set at the time, so probably was something like a left hand bit, just something I had laying around that I used as one, and backed the pin out), Common sense should had told Me the iron was the same difference, and actually the heat probably does'nt penetrate as well as smoking a bit up in a deeper hole.
I especially like the welded bit, reversal thing, makes me want to stick a good pin in a piece of scrap, cut it with a hacksaw, and see if I can pull that one off. that would be nice trick for the next time one comes around, maybe then I won't be so scared to take it on.
Will These work the same with brass & alloys though? I don't even want to guess how to get a glass pin out. Thanks Greg C
