Chris, you're right of course that this can be a little unpredictable. It's always possible that there will be something unusual about a specific case. It might turn out that removing the old cork is unusually difficult. Or the old cork may have been covering some irregularity in the tenon or cork seat that needs to be addressed before putting a new cork in place. Any such unexpected difficulty will add time and cost to the job and can't really be predicted ahead of time. I think all of us were making the basic point that it's normally not a difficult or complicated repair that Dan should avoid because of a potentially high cost.

I've read this before - not sure if in something you wrote or something from another tech here or on Klarinet. But can a fit that's too tight between the tenon itself and the socket (whether it's a barrel or a bell or even the middle joint) contribute to the problem of binding joints, the kind of thing people with new clarinets sometimes experience when the weather warms up and the wood expands? How close a fit should it be without the cork? Does rocking depend more on the fit or on the sharpness of the right angle at the top of the tenon?
