 Wobbly Tenons Should NEVER Be A Thing!

Especially on high end oboes equipped with metal tenon rings which SHOULD be a perfect fit in their respective sockets even without the tenon cork fitted. It's not the cork that creates stability, it's the fit between the tenon and the socket and the tenon cork is there to provide both an airtight seal and exert the necessary outward pressure against the entire socket wall to hold the joints together. A thicker tenon cork won't cure a wobbly tenon.

I had to make and fit new tenon rings to this Moennig Albrecht Mayer model oboe as the middle tenon was undersize and rocked like anything in the lower joint socket which not only creates mechanical unreliability, but doesn't feel great whilst playing and that's the same with all woodwinds.

Not only that, the top joint bore and the outside of the tenon and top joint weren't concentric, so I've no idea how that could happen as the outside is normally machined down to the finished shape while the joint is mounted between centres at either end of the bore. Even if the bore has warped, the reed socket and middle tenon bores should still be concentric with the outside.

Anyway, it's sorted now, but should never have been like that and shouldn't have passed quality control.
