This is my experience as well. Actually I'd rephrase the statement to just read "if the shanks are appropriately knurled, there is no problem...." Again... most of the glues used are not meant to be used as fillers. Nearly every hammer I've seen come loose through the years were detectably loose fitting. Seems to me like the "filler" is what breaks... not the glue adhesion to the wood parts. You dont need a lot of glue to do a lot of good... any more then you do when you glue two flat pieces together and clamp them. Cheers RicB If a good knurler is used and the shanks are properly knurled, there is no problem in dry fitting them in such a way that they can be aligned fore and aft etc. Then the expansion of the shank makes a tight fit to the hammer bore hole, as you say. The problem is that few people own a good knurler, and that they are not available through the big box suppliers. Jurgen Goering
