On my clarinet, the posts that hold the key axles (sorry I don't know the proper names of these parts), how are they held in? screwed or just press fitted?
Reason being, one post is very slightly loose, if you push it, it moves about 1/32"
thanks..knotty

most are screwed in.
remove the post, wrap a piece of thread around the screw threads, and reinstall it - that should tighten it enough to hold it.

If the thread in the wood is reasonably intact but the pillar is loose so it rotates a few degrees off from where it should be, take the pillar out and put a single drop of superglue on the very end of the pillar thread and screw it back in, making sure you line it up correctly with the opposing pillar (use the rod screw to check it). The superglue will go off and tighten up the pillar.

OK, screwed in, got it. The pillar doesn't move when working the keys, I just noticed it move a bit when taking the clarinet apart.
You know, these old clarinets, I can't help but imagine all the things some of them must have been through, abused, iron gripped and twisted, ignored for years. Amazing how well they fix up with a bit of work, amazing.
Thanks...knotty

Another fix, providing the threads are OK, is to unscrew the post a couple of turns, push pumice powder under the base of the post, screw the post back, and remove all remaining powder.
Some posts are molded into plastic, and often quite poorly.
Some posts have an unthreaded stud into the timber, and an associated 'tab' and wood-screw to secure the post.
If a post is loose, and a spring is mounted to it, then that spring will tend to turn the post slightly, and that may cause the key to jam somewhat against the post.
Loose posts interfere seriously with the accuracy and reliability of linkages between keys.

I am currently working on one that, when it arrived, looked like someone had tried to repair it with a quarter in screw driver, a pair of pliers, and a claw hammer. With gentle key straightening on a jeweler's anvil and lots of TLC, it is turning out very nicely. It's amazing what can be brought back to useful life.
