Re: Tenon Rings loose - should they be glued on?

You don't want socket rings to be fitted permanently - you still want them to be removable as and when they need to be. No metal fittings should be fitted in such a permanent manner that they can't be removed easily if they have to be, but some metal fittings such as tenon tip rings are usually burnished on and can't be removed without any damage - if they are loose or leaking, they can be sealed by wicking superglue into the gaps between them and the wood.

If you want to fit them with shellac flakes, either heat the socket ring and melt the flakes on the inside edge and refit the socket rings while the shellac is still molten and then carefully heat them while in situ to make sure the shellac has flowed and filled in any voids.

Or dissolve the shellac flakes in alcohol and coat the socket ring and the recess with that, fit the rings and leave it for the shellac to harden which can take time as the alcohol will take time to evaporate. Heating the socket ring will speed that up.

With superglue, you can add more until the voids are all filled in and no more glue will wick into the gap between the socket ring and the wood. That's also a good way to fill any gaps between metal tipped tenons and the ends of the tenons if they're leaking.

Speaker and thumb tubes are best installed with shellac so they can be removed by heating them by inserting a heated mandrel, then pushing them out from the inside with a wooden dowel. If they're threaded, then they can be heated and the threads can be coated with beeswax before being screwed in.
