Lim, The main idea of the wall paper remover is to increase the water's ability to penetrate the wood cells.(lower the surface tension). This can be accomplished with alcohol, as well. Soak the hammer butt/shank with alcohol and follow with water, (or soapy water, if you choose). All amounts to the same...penetration. I prefer the alcohol and then water, because it does not necessatate complete drying before gluing the parts back together. I, too, have used plain water. It works, but it just takes longer for the water to pentrate sufficiently. (we all are probably in waaaay too much of a hurry, so just use the water and smell the roses.<G>) Joe Joe Garrett, R.P.T.

I have tried using just tap water and heating the screw until the water bubbles and still managed to extract the shank, most of them on white glued hammer shanks.

Contrary to popular belief, cold hide glue has a very long shelf life. Even though Franklin says is doesn't, it does. I have a bottle of cold hide glue that was in my previous "Gorilla Tool Kit", that was stolen and then recovered many years later. The darn stuff is still just fine! IF, you leave the stuff in the car and it goes through many cycles of freezing and high temp it will have a shorter life. I have not found that the heating/cooling has any effect. However, since I use a lot of hide glue, the bottle gets filled often, so there's never any reeeeaaaallllyyy olde glue hanging around. Yes, I do clean out the bottle and sterilize it with each fill up!<G> I hope that helps. Regards, Joe P.S. On the Sheet Metal/shank removal system, I forgot to give a date: 1975!

If so, does this affect the already-short shelf life??

Trick: put the Hide Glue in a coffee mug with very hot water. Let set while you are prepping the repair, (always dry fit!). The heat helps the cold hide glue to set faster. I'm sure some brainiac will come up with a reason why this is so.<G> -------------- next part -------------- An HTML attachment was scrubbed...
