Hiya Philip, thanks so much for that, will have a read through now - I just did the worst, cheapest, knock-about pipe with a drop of superglue run around the inside of the shank with a mostly stripped down cotton-bud (I forget what you guys call them, earbuds or something?) That seemed to work a treat so that's one way I know that works! now to find more that are a bit more to my liking, don't really like the thought of adding anything bonding such as glue, nail varnish etc. Warning - DO NOT stick your nose on the end of the shank & inhale after supergluing, eewww, you get a headful!
Only the tiniest of droplets is required when using superglue, it really does make the wood shrink quite a bit!
