physically getting hammers on shanks

[Jon Ralinovsky]

Ed,
Are you using a jig at all? I would suggest looking at Bill 
Spurlock's vertical hammer replacement brochure on his website at 
www.spurlocktools.com. I think it will help with the consistency of 
the results.

Respectfully,
Jon Ralinovsky
