removing shanks from butts

[piannaman at aol.com]

Try this one I learned a while back in the RPT tech prep class(intended for shanks broken too close to the butt): 
 
clip the shanks almost down to the butt 
make a fairly flat surface on the shank stub near the butt
drill a small hole in the center of the stub
enlarge the hole with a slightly larger bit
SLOWLY screw in a small screw fairly deep, leaving the head out far enough so you can use your shank exctractor (all the time being careful not to crack the butt assembly)
Extract screw and hopefully shank with it.
 
This might work.  AT the very least, it will allow you to center the drill bit you may eventually have to use.
 
Good luck!

Subject: removing shanks from butts


List, 
 
I am about to rebuild a set of hammer butts, and put in new shanks and hammers. However, I can't get these pesky shanks out of the butts. I have done everything I've learned..... breaking away the collar, soaking the shank/butt joint with wallpaper remover, even applying some steam to help loosen the glue (it is hot hide glue). 
 
I've only tried it on shanks that have hammers already broken off. So I've been using a shank clamp as the end point for the shank/butt remover to push against. The clamp keeps sliding up the shank before the shank/butt joint will break loose (and I've tightened it really hard, to the point where the shank is pretty smooshed). 
 
Does anyone have any suggestions? 
 
Thanks, 
Ed
