Has anyone made a slide adapter?

A mouthpiece adapter is a tube of metal with a taper on the inside, and another taper on the outside. It seems to me the same concept could be used to connect a (let's say) Bach 36 slide to a 42 bell section. Has anyone ever built such a thing? The lock nut might be tricky.

And yes, I'm sure all the same caveats about "not a good idea" would apply in spades.

These days, you can just put on an Edwards .525 tenon. I've had a slide like this, played great! Never used it.

Wasn't someone making slides with interchangeable tenons at one point? Maybe BAC?

BAC did this like 10-12 years ago. I recall that before the bell design was finished the original Elliot Mason slides had adapters to fit King, Conn, and Olds style bell sections.

I made a slide adapter once, but it turned out to be a piece of tinfoil folded over 2 or 3 times - very thin. I think it allowed a 79h slide to be used on an 8h bell.

I could see some utility in a modular slide receiver. In addition to better fitment for various tenon tapers and ODs, it would then be possible to match the tenon ID and create a smooth path from the end of the tenon to the beginning of the valve intake or gooseneck tubing. That could reduce or eliminate the small chamber that otherwise exists when the nominal bore abruptly widens and then constricts again inside the slide receiver, which can act (as I understand it) as a small Helmholtz resonator. There are solutions out there for addressing that unintentional chamber, like the sleeve inserts made by Hagmann, or the multi-taper receiver (https://thayervalve.us/store/Multi-Tape ... p718999834) that Thayer offers. But, if you're switching slides with significantly different tenon IDs (going from a .547 bore slide to .525 on the same bell, for example), being able to change the receiver to match would be convenient.
