How to adjust cylindrical rotors (otherwise they could not fall through an open casing) for air-tightness ??? After they show signs of wear ??? ============================================================ ===================================================

I asked Johannes Finke (of Finke horns) about this after reading (on the Finke website) how they make their valves. Herr Finke told me that their rotors would drop straight through an open casing. So, there's no taper on the rotors, but I'm not sure whether Finke bearings (or "axles") are tapered. I do know the thrust in a Finke valve is kept in check with a single ball bearing on top, adjusted by a setscrew... which is an extraordinarily cool idea if one intends to keep a horn for a long while. Also, this is not said by way of any DiSAGREEMENT with what you've stated. It's simply more information towards further discussion on the same point.
