Tech/maintenance I have no words...

I have a feeling I've actually seen a sax crook with a tenon cork fitted - at the Frankfurt Musik Messe. I'm also pretty sure it was on a Chinese manufacturer's stand.

There's no reason why it can't be done (it would be very similar to the crook joint on a bass clarinet) - and it would have a number of advantages, though cost wouldn't be one of them.
Then again, having a tenon cork replaced is substantially cheaper than having a sax crook joint tightened.

The obvious issue (which may not be an issue) is that it would seem that it would force a bore constriction at that point. Not to be confused with the snake.

No reason it should - you'd just make the tenon sleeve to a larger external diameter to accommodate the cork channel, and a correspondingly larger receiver. The internal diameter of the tenon sleeve would remain unchanged.
 
What about the cork being subject to expansion and contraction, as well as a bass clarinet being made of wood or abs plastic?
There are metal clarinets, and they still use cork on the tenons. One could look at the coefficient of tthermal expansion for various woodwind joint materials, but given the limited range of temperatures performed and stored in I would think be insignificant.

It won't be a problem. Metal receivers/sockets are quite common on clarinets, especially basses - and cork is used for joints because it'll take some compression and recover when removed from the socket.
It'll eventually lose its elasticity after a good few years - at which point you just swap it out for fresh cork.
While it's in good shape though it provides an excellent seal.
 
How long before somebody suggests the cork will dampen the vibrations?
Ah but then you have a more complete connection between the tenon sleeve and the receiver with cork - and the cork might only be 1mm thick (uncompressed). The closest you'll get to a complete connection with a standard joint is after you've had it properly fitted and lapped (pricey)...and from that point onwards the joint will wear.
Swings and roundabouts?

I should say that I'm all in favour of maintaining the status quo 'cos I make quite a lot of money from fixing loose/bodged crook joints.

But folk derive a lot of benefit by your restoring those crooks to factory specs, look and feel. The assortment of special tools you have manufactured for such work is amazing.
 

Similar threads... or are they? Maybe not but they could be worth reading anyway 😀
