Re: Barrel Stuck to Top Joint

There has been considerable discussion here of using temperature change to help separate the stuck barrel from the upper joint. However, as a retired physics teacher, it is not clear to me that everyone here understands how that temperature change would effect this situation.

--Everyone seems to understand that heat will tend to cause a material to expand. However, it does not seem clear to me that everyone understands that the expansion will cause any hole cut in that material (eg. the socket in the barrel) to enlarge as well. Thus, gently warming the barrel from the outside would cause the socket to enlarge and, hopefully, be helpful in removing the barrel. The less perfect heat transfer from the barrel to the tenon (across finished surfaces) should allow for some loosening before the tenon gains enough heat to begin its own expansion.
--By the same token, gentle cooling from the inside should cause the tenon to contract slightly and, by the same logic, do so before the socket begins to contract.

On the other hand, if possible, my preference would be to just let it sit until the wood has a chance to return to the condition it was in when the joint was assembled.
