Hey there. I am looking for recommendations for a technician who can do keywork customizations for bass clarinet. What i want done will require a small tonehole to be drilled below the Low E/B vent as to vent the low E but then to automatically close when i press the register key so the B is in tune. The low E on my bass clarinet is 30 cents flat and it sounds like a whoopie coushion compared with the surrounding notes.
Ideally this technician will be someone with extensive experience with tone hole placement, drilling, and keywork fabrication. Shoot out some names!
The closer to DC or Cincinnati the better. (my two locations.)

If you have a low Eb bass, why not leave the register key linkage out of the equation. Just have the touch piece for the new Low E vent placed somewhere near your thumb? You would then operate it when you need to have the Low E more in tune.

Has your bass got the original bell or is it a replacement? If it is a replacement and from another make or model bass, then the E/B tonehole (the one on the bell below the socket) could be the wrong diameter and in the wrong place.
Fitting an automatic low E correction vent is indeed possible - it will be like that fitted to Selmer Recitals and Backun MoBas (only it will be closed by both the low Eb key and when the speaker key is held down) but with a small vent hole located immediately above the lower joint tenon shoulder like the low E vent tonehole/pad cup seen on a Yamaha CSGIII, but it will be costly. Far more costly if the vent key is fitted on the bell itself if that is even possible or practical.
A RH thumb key would be a better, simpler and a less costly option.

Thanks all for your recommendations. My instrument is to low C. And yes I'm well aware of the complexity of this job. I would not want a manually operated key though i have considered it. I've owned a yamaha CSG and that made me want to jump through a brick wall trying to operate it. A manual key would be more headaches than none at all. Imagine going from a low C or C# to a low E like in... Shosty 7.. too much thumb action. I would have to minor in bassoon for that. Dave and i are in touch.

Oh - I assumed it was on a low Eb bass. Yeah - an extra thumb key isn't an option with all the other thumb keys.
An automatic low E vent will probably be best suited on a low C bass as the low Eb key is in one piece, so that will make the linkage/adjustment more reliable.

yup. And on top of that, my bass has a connector between the two joints as to make sure the two joints are always alligned exactly the same way everytime the instument is assembled, so creating a linkage from the register key touchpiece to the lower joint will be easy to keep in adjustment.

I would take issue with your last (optimistic) statement. Keeping the register mechanism in adjustment requires much more than just having the two halves of the bridge key aligned laterally. There are about a dozen other interfaces between moving parts that have to be maintained as well. Cork shims wear, adjustment screws wear or back out, etc.
