Another maintenance video; this time, a quick walkthrough of how we lubricate axial flow valves in the shop. Made using an Eastman 829 valve section and Hetman Light Rotary and Bearing/Linkage oils...
The video from SE Shires shows their technician applying rotor oil down the slide receiver tube versus the f-attachment tube. I prefer this for better action and it prevents the oil from getting mixed with tuning slide grease.
I think it's funny to call it a 101 course. I found axial valve clean and lube more like a med school course, or at least a MUS250 level. I love the valves but geez... at 66 my dexterity is not what it used to be. Putting the horn back together (picture the poor bass player with two of them) is a time eater. Great vid as always.
I used the “rotor” oil to lubricate my thayer valve since I don’t have the “light rotor” oil. Would it affect the valve if I use and add a different oil?
I generally haven’t had a lot of issues with this, especially if you are changing weights of oil within the same maker (I.e. Hetman, Ultrapure, etc.). Combining different makers’ oils can occasionally cause valve response to slow down but gradually “flushing” out the old oil with the new will typically correct this. The other option with the Thayer is to disassemble it, clean it out, and reassemble with the new oil; I don’t do much work on my horns but even I feel comfortable taking Thayers apart...
Schmitt Music Trombone Shop Thank you for your reply! The oil I use is still Hetman. Should still dissemble it anyways if I want to put the light rotor oil, just to be safe, unless it’s still okay not to?
