Rotary Oiling

[Three Valves]

I would sort of hope that my rotors fit a little closer than for a vacuum to be able to get past the rotor side walls far enough to pull oil into the spindle bearings.

Why oil the bearings if no oil 'gets thru' where it's needed? Oiling the bearings only on their surfaces, it seems, won't do much. Doesn't the oil need to 'coat' the entire spindle bearing nub? Even on my 'tight' Meinl CC with great pop/compression, I pull the slides to vacuum the oil in and coat the bearing nubs

I'm actually kinda new to Marvel Mystery Oil -- started using the stuff maybe a month ago. Love mixing it with other oils. It's good, cheap stuff

The hole isn't there for oiling, I would never consider using it for that.

It’s there for adjustment, and

I oil my fifth rotor through the screw hole on the bumper retaining plate. It's been a through hole on every rotary instrument I've owned. Get a small standard head screwdriver, pop out one screw, pour a generous amount of your favorite valve oil in via needle oiler, and forget about it for a while. Excess will inevitably work its way out through the spindles of the rotor. I've found that this works well for me. The trick with the slide pulling also works well on quality horns. Didn't work on my clapped out Cerveny 686. Those rotors were so worn that they'd vibrate on low notes with any valve oil I put in there. ATF ended up being my lubricating means before I sold the horn. It actually helped the compression of the horn a lot...
