    Excellent idea! Hadn't thought of that.

    I clean and dry the valves and casing, then paint the valve with black magic marker. Reinsert unoiled and push up and down a couple of times. Disassemble and look for scratches. If there are none, then the spring or way too much wear is/are the culprit(s)!

    Magic marker comes off with acetone or lighter fluid.

    I do the same with graphite from a pencil. It works on slides, too.

    I tried that and because I didn't get it all off before I oiled, I had mush.......... Cleanliness is next to godliness. The messy/lazy need more security.

    My 56 Committee cornet has the same problem. The second valve sometimes comes up slowly after the horn is warm. My friend's 49 Committee trumpet is developing the same problem. I've had it looked at by several techs. The only solution I've found is to slightly offset my middle finger over the button on the second valve. I believe the horn had been played that way for a long time and the valves are worn that way. One tech suggested we try a spiral lapping technique he'd read about. Let me know if you find a solution. Good luck!

    Where in the U.S. can you now find pure graphite ... in its natural state it is not pure ... it is not used alone in pencils produced here any longer having been once bound with clays, it is now bound with polymer resins ... and why they now call such "lead" is a mystery to me as such is also not the element Pb with an atomic number of 82 as we now know is poisonous and strongly affects our body's neural system.

    Perhaps crushing your wife's diamonds to dust. THEN you will get pure.
