    Perhaps the definition of "Corruption" may be somewhat more fluid in contemporary Chinese culture.

    Perhaps, as in Hawaii, Haoles are considered fair game. :dontknow:

    As poorly as the pistons were "hand lapped" and "hand fitted" monnels I've decided to return the trumpet to the seller for a full refund and spend a little more money on a different brand. I mean the lapping job is sick. It looks like someone used coarse grain sand paper. After cleaning the horn and applying valve oil, you can't even spin the piston in the cylinder. They are so out of tolerance they aren't concentric. Really poor quality. This should not be that hard to finish the job to at least a student level horn for $300. Anyway. I get my money back and will try again with something else. On another note. I put my Bundy Home build C with the banner bell on it to the tuner and in Bb it comes in pretty tight and tunable, so when my new shorter bell comes in and I get it in key of C I'm eager to see how my home made C trumpet performs against the next one I purchase.

    There is even big differences in the quality of "stainless steels". Material quality is one consideration, what we do with it is also every bit as critical. Monel has the advantage that it wears - the casing not as much. With stainless, the lions share of wear is transferred to the casing. We pick our poison!

    here are some pics i grabbed of the valves before shipping out this morning. Note, I had washed and lubed. However, the valve oil is already nearly black after maybe 2 minutes of playing the horn before I decided it would not work as the valves kept sticking. Also, after cleaning and lubricating, the valves do not spin freely in the cylinders. Also, the valves were not numbered. You'll notice the blackish valve oil but you can also see "polish" wear spots randomly located and polish streaks on the pistons. You might also be able to see the poor porting as well. These are "hand lapped/fitted" pistons.

    My 30 year old Conn 100B's pistons look better than that, and I flogged it mercilessly without cleaning it more than once every year or so through 8 years of school.

    Good grief! The valves in my 70 year old Lafayette look much, much better than that!

    There are competent techs that refuse to work on horns like this as it can be a never ending story. I suspect if we lap enough to get them moving freely, they are so leaky that the horn plays worse. They may even be so loose that they bind in different ways.

    Yep. It is never a good conversation, but I have had many conversations with parents about how the value of the repair exceeds the value of the instrument, and how their instrument was not built to last.
    You always have to judge the personality of the customer, and NEVER say their instrument is cheap.
