Hey just posted about oiling tuba rotors. Is the info I posted useful?

Did I leave anything out?

Thanks!

Something that is rather useful for making sure that the oil spreads through the whole area, is to use the slides to pull the slides without pushing the valve when applying to where 14 is pointing, and to put the slides back in without pushing the valve when oiling 11 or 12. After doing so, the valve will be a bit harder to move the first time due to pressure, but it distributes the oil to the rotor better.

Strictly speaking, http://www.osmun.com/reference/Rot_Maint.htm from Osmun Music is for horns, but they directed me to it when I had my rotary in there.

Personally, I find this collection of videos on Jeff Funderburks web site at The University of Northern Iowa to be quite comprehensive and a necessity to any player dealing with rotary valves for the first time.

+1!

That's where I learned to take apart rotors for the first time!

Thanks bloke. I try to give useful information, but hopefully not enough information for people to try and get themselves into trouble.

Can anyone take apart rotors? Sure. Should they? Ehhh...maybe-maybe not. It depends on the person and really on a case by case basis.

I think advanced players should know how to do it properly. I don't think beginners should fuss with taking apart rotors at all. Just my opinion, I could be wrong.

Thanks to everyone for all of the suggestions. I will add them to my post and let visitors give them a look!
