>>Mike, thanks for the response. I was wondering whether I should heat the
>>glue or try splitting the head with nippers--Reblitz does recommend this on
>>vertical hammers where they cannot be pressed off.  But I esp. like the idea
>>of grinding down the point on the Schaff hammer press; I hadn't thought of
>>that and it makes sense. 
>>Just what I was looking for--I appreciate it.
>>I don't have a proper knurler, so for the time being, I am knurling with a
>>pair of small pliers, careful, tedious work, but it seems to work ok.

>>Gary,

>>A couple of things that have worked for me: 1) remove the glue collar. 
>>This is necessary to let your press seat squarely against the hammer. If 
>>it's hide glue, it should be brittle enough to chip off when pressed 
>>with a not-too-sharp knife. 2) Pre-heat the joint with a heat gun. 3) 
>>reduce the size of, or remove completely, the point on the end of your 
>>shank press. Schaff's current offering has a big blunt point that does 
>>excessively enlarge the end of the shank.

>>Are you trying to save the old hammers? If not, consider a different 
>>removal method that sacrifices the hammers to reduce the damage to the 
>>shank. Such as splitting the hammers with diagonal cutting pliers. 
>>You'll still need to re-size or re-knurl the end of the shank to get 
>>consistent fit to your new hammers.

>>hope this helps
