I seem to be getting the impression that some of you are heating and bending the shank to move a hammer. I personally think that might be causing the problem Jon first mentioned. It has been my experience that the best way to burn hammers is heat the glue joint enough to allow me to twist the hammer. I then hold the hammer in its new position for the glue to solidify. I have never had a hammer move after that. I don't think the heat does any damage to the glue. I use Tightbond, BTW. </DIV> <DIV> </DIV> <DIV>Wim </DIV></FONT></BODY></HTML>
