Mixed Joints
« on: June 24, 2021, 12:51:43 PM »
No, we're not talking about the smoking kind of joint here!


Working on a clarinet that has no branding.  The bridge keys appear to be Selmer.  The upper joint S/N is411013.  The lower joint is engraved below the socket ring: HTCL 000667.


The mouthpiece is unbranded, plastic, and hand engraved with TMS #7.


The barrel and bell are wood, while the body is hard rubber.  The bell is a Boosey & Hawkes Edgware.


The case is Yamaha with stenciling painted on it and a number stenciled on the end, suggesting that it was a school instrument.


So, I'm guessing the instrument was cobbled together from joints that the students hadn't yet broken.


We'll see how it plays after I've done my work.


Photos later.

In the industry we call these Frankenstein clarinets! Long as the bore sizes are relatively similar, it should work out reasonably well enough.

It's not worth bothering with in my opinion.  Use it for spares.  There are plenty of better candidates for restoration out there.

I agree with Dibbs. Besides possible bore issues; it is likely some of joint lengths will be designed to be different.

I’m close to completion and will post photos of some of the details later. Should finish it tomorrow.


Thanks for the comments - I’ll know better next time - if I don’t forget!

The bridge joint bores don't match.  Upper 15.03mm, Lower 14.75mm.  Which I suppose is why the lower joint is very hard to play.  I've leak tested all pads with a light.


Is it worth reaming the lower joint out?  I realize it takes a special reamer to do that, and don't have any.


Thanks

Short answer, probably not. Unless you've got something super special, that would be too much time and effort for a run-of-the-mill Frankenstein.
