| Valve oiling
I have often read on the forums that instrument valves are never to be rotated in their casing in the process of oiling them. I just went through my entire 'accumilation' of trumpets and cornets, all 57 of them, cleaning and oiling the valves. On none of them did I find any radial scoring, even when examined under a bright light and using a magnifying glass. I KNOW that upon each oiling since my ownership, the valves WERE rotated to evenly spread the oil upon the entire surface of the valves and casings. If the practice of never rotating he valves for fear of scoring them was a valid reason for not doing so, my horns would be a showcase demonstration for not doing so. I have found the reverse to be true. My valves show no such damage. In addition, how is one to find the exact point in the rotation of the valves where the index key will align with the casing slot without at least some rotation being used?
On this safari through all of my horns I cleaned the valves and casings with a bit of Zippo lighter fluid,( naptha ),on a section of Bold brand paper toweling, to cut the old oil and totally clean the attendant surfaces. I have tried lesser quality brown paper shop towels and had a good bit of valve stickyness from residual paper lint from the poor quality recycled paper fiber.
