Re: Tenon binding

It's not loose tenons that are the issue here due to compressed or worn corks, but the wooden tenon rings binding in the sockets. Swollen corks won't cause tenons to bind in their sockets unless the instrument is left assembled and any water that collects in the sockets remains there unchecked. But for an instrument to become difficult to assemble and take apart, the usual suspect is binding tenon rings.

No amount of cork grease will cure this and the only real cure is to have the tenon rings skimmed to remove just enough wood so the tenons fit in the sockets without binding nor rocking, so scrape a little off at a time and check the fit. Then inspect the tenon rings for binding caused by high spots which will look shiny against the dull freshly scraped wood and then scrape the high spots. Then check again and repeat until the tenon fits perfectly.

As for clarinets prone to this, the usual suspects for me when I worked at a music shop were wooden clarinets made by Buffet and Leblanc (which were the most popular in my area) within the first few months of ownership and are therefore under warranty.

Binding tenons on new clarinets aren't something that will sort itself out in time, so they will need to be addressed as soon as they bind instead of leaving and putting up with them.
