ShopTalk: Epoxy bonding problem

[Leo Noordhuizen]

A basic question:   I have a question on preparing metal shafts and iron heads for the epoxy. I have no problem at all with the bond between grapite shafts and iron or wood clubheads. However Iron heads on iron shafts are getting me nervous. I am lucky that nobody had yet the surprise of a flying clubhead, but now and then there comes some creep in a clubhead. I just got 2 back for a friend, and with my own set I am going to re-epoxy the head of 2 irons.   My question: What is the best way to prepare the bore and the shaft to get an optimal bond ?   Regards, Leo - The netherlands
