    No matter how much I oil my valves my valves keeping sticking. Im pretty sure its because of the wear of plating on them.
    How much would it cost to fix this?

    There are several way you can go....I had a nice trumpet that was a great player but the 2nd valve would stick.
    So I started using something that removed that varnish looking stuff and it wouild work doe a few weeks and then I had to do it all over again!

    I would call Kanstul or Akright and ask them. I had a trumpet completely over hauled a few years back and if I remember correctly the cost of doing the valves was over 1/2 the price of the overhaul. I am think somewhere around $400 -- $600.....if memory serves me..

    sell it on eBay, and buy a different one!
    Valve job costs $400-500... not worth it for the average Elkhart model 37

    I had one of my Olds SuperStar trumpets re-done at Anaheim Band Instruments. They do not do valves but they sent it to Anderson's in Indiana (where Bach has them done originally). The valve job added $295 to the total bill. The valves look and work like new now. Well worth the price.

    But, before you do that, you need to make sure that is really the cause. There are many other possible reasons for sticking valves. Wear is not one of the more common ones. My SuperStar valves did not stick at all. I had them done because someone had attempted to fix a piston that they had dropped and had screwed it up so that it would not align properly.

    Anyway, there are several threads here that deal with approaches to overcoming this problem so it would be worthwhile checking them out. Or, try Hetmans or Ultrapure oil. They have solved a lot of sticking valves.

    You can poke around the Dr. Valve site and see what he charges. He is reputed to be very good.

    +1 on CBK's suggestion to try different valve oils. I had always used Al Cass. One (used) horn I bought a year ago had sluggish valves and I just thought it was because they were old. But after washing the horn I tried out ultrapure and saw a big improvement. They still aren't super fast, but no longer stick.

    Your valves are Monel, not plated. So you are not have issues with worn plating unless the valves have already had a refit. The replies so far make sense, why don't you let a competent repair tech look at your instrument and assess what needs to be done?

    WHere are you?

    If more oil doesn't help, the next step is not plating. Where did you get this idea?

    Valves stick because they are dirty or damaged or the casing is damaged. Excessive wear COULD lead to sticking with very thin oils. A tech sees the problem in minutes. If you really have no idea, why fix something before being sure that it is broken?
