Bell Receiver Preservation

Post by harrisonreed » Fri Dec 13, 2019 6:15 pm

Does anyone know what type of blue tape manufacturers use to protect the bell receiver (the part that the nut scratches up and that your hand acid eats away)?

Are there any other ways people know to prevent this part from wearing down? Mine takes a beating.

Rubber band, o-ring, get a King or a Rath or a friction fit horn.

None of those protect against hand acid. I like the o ring idea though

One collateral benefit of the Neotech trombone grip is your hand stays away from the horn. Even if you don't install the grip itself and only play with the mounting bracket on the horn it is protected.

Are you talking about for like a trigger horn or a straight horn?

You must have monster hands if your hands are big enough to touch the bell receiver on a trigger horn!

Leather wraps are probably your best bet for both. Just have to make sure to take them off and clean under them frequently.

You can also just make sure to wipe down every time you put the horn in the case. Not as foolproof as finding a way to protect the horn with a wrap of some sort but it'll definitely increase the longevity of the part.

Yeah, I'm talking about the part of the bell that the slide trunion goes into. It usually is the part with the nut on it, and new horns come with blue tape over this area. My hand goes well past the nut and about halfway up to the rotor on my Edwards (any horn, really). My hands are indeed huge... They would be great for piano if I hadn't rolled a one for dexterity.... OK, I'll let myself out...

Slide grips don't cover this area. But blue tape does

Have you considered shrink-wrap?

Leather specialties used to make a different version that does, in fact, cover this area. You had to hold it out of the way to put the horn together, but it had a big flap to cover the nut. I think it also had velcro to hold it down, but I never had one myself.

I have one of these older leather specialties wraps on my 42. It does cover a little of that area (it covers the nut and just a hair past). My only real complaint with it is that hand pressure against it can occasionally loosen the nut while playing. It happened to me all the time when I velcro'ed the flap shut. I play with it flapping loose now, which isn't too much of a nuisance, and it doesn't happen as often.

I believe the brand is "Nitto." It's expensive to buy by the roll (~$50), but your local repair shop may give/sell you a few feet. We use it to protect the finish when sanding key feet and similar repairs.

Thank you! I can probably buy Nitto brand tape on the cheap here in Japan.

So, it's easy to get Nitto brand tape here in Japan, but there are literally a hundred different kinds. Do you know the tape type you use? It's like two different numbers separated by a hyphen in most cases, looks like.

Allied Supply doesn't list the specifics in their catalog, but it is a 2" x 660' roll. It seems to be their SPV line in the 2" width.
