Here's a question for you clay pipe fans out there. Would there be any disadvantage to fabricating a bone or horn sleeve to go over the stem of a clay pipe? I was thinking that making a 1 to 2 inch sleeve for the bit end, then gluing it into place with non-toxic white glue, might be a way around lip-sticking and pipe-notching, which I see as the biggest drawback to clays. Has this been thought of before, am I on to something, or is it a terrible plan?
