Ball and socket linkage lube

Postby BflatBass » Tue Sep 18, 2018 10:44 am

I just bought an old St. Petersburg 202 with the old ball and socket valve linkage. These joints will need lubricating from time to time so I'm wondering what to use. Since I've worked on cars and motorcycles all my life my first inclination is bearing grease but that just seems a little dirty since it turns black after use. So after doing a little poking around online I'm seeing various products available that might work. One video I watched said tuning slide grease would work. The only thing I've found that looks like it's specifically meant for this is Hetman #15 ball joint lube.

Recommendations?

Thanks,
Robert

Recently, I went over a B and S horn with this style of linkage. I found that Selmer red (Now branded as Bach tuning slide grease) Works very well. It's thick enough to seemingly last a while, and It's incredibly smooth and quiet under operation. Here's a link to what im talking about.

How often are you willing to do it, and how much mess are you willing to tolerate?

If the applicator has a syringe I'm willing to apply it every week. I only play in one band once a week and practice about 3 times a week. I'd rather there was no mess. A little mess would be ok if there was no alternative and a smooth quiet operation. If the lube is literally dripping off the linkage during use I'll switch to something cleaner and put up with more noise.

Any sort of grease will end up – mostly – on the outside, and will collect dirt.
Off-brand 30 weight oil – applied by needle applicator – might be good for a week or two, but any excess would drip, and dirt would collect in the general area.

As STP Oil Treatment is inexpensive - and has a nice even consistency similar to that of honey, you might consider applying it to each link's bearings with a cotton swab.

It is going to be difficult to locate any lubricant that is actually too thick to use for this application.
