---------------------- multipart/alternative attachment Roger, Thanks for the input. You have an astounding amount of knowledge, and I appreciate you sharing it! Is polythene impervious to acetone? Where might I find a sheet of it? If I understand correctly, this method washes the hardener deeply enough into the hammer so that we are left with an outer layer of felt that we can needle. It sounds like an operation to be performed in an area with adequate ventilation. Thanks again, Dave S.
