Hi John,


I believe soaking the shanks would create some of the problems one was
attempting to bypass. Is this your method for removing the glue without
reducing the shanks? If you soak the ends what's to stop the soaking agent,
whatever that is, from continuing into the shank and causing it to warp,
twist, bend etc.? Secondly the assumption is being made that the glue being
used would be hide glue. I have found the relatively new Titebond Molding
and Trim glue to be a superior glue for hanging hammers, requiring a clean
wood surface with no old glue.
