    I have used a rag... slip itthrough the little slit and give it a yank....BUT their is REAL RISK of breaking the solder joint where the U-tube is welden onto the connecting pipes. The rag doesn't have a sharp edge so there is less risk of damage to the pipe.
    I only do this if I am sure there is no other damage and the pipe is just tight.
    If you have a shop nearby , use it, especially if you aren't familiar with the horn.

    The Ultra-Pure greases, both the regular and fine, work extremely well. I think they're better than plain vaseline.:thumbsup:

    Correct, if it resists a quick yank, then just yanking away can distort the chamber , the crook , twist the slide, split the seams etc. Knowing when to stop is the key.

    For info on the 2nd valve slide, we always use a rope and slide hammer to start. then soak in penetrene, then heat and slide hammer again, if it still resists, then oxy / acetalyne and desolder all the seams and remove it in parts, any stuck slide componenets then get a slug soldered into them that allows us to turn the pipe sideways rather than trying to push pukl it, the sideways twist breaks even the most stubborn joins, once dis-assembled we can then clean and put it back together and re-assembled.

    Again the key is knowing when to stop, or knowing ones limitations, but I always encourage people to give it a go first.

    KT - make that +6 old guys that will stick with vaseline on the slides - just a dab and wipe off, then reassemble. Worked for as long as I have had a horn.

    I usually put some lycra type of material through the cap and give it a yank. T-shirt material works, rope is an interesting idea. Usually does not stick again once pulled and lubed.

    truth is! -- how can we trust anybody on an anonymous forum??? You just have to glean what you can from this or any other forum!! --:dontknow:
    OK - some of these people don't remain anonymous -- and can be checked out --so you either have to check them out or just blindly follow their advice -- but I guess you have to figure out who's advice you can trust.:shock:

    Try this-


    1. When you insert the slide into your horn, leave the smallest gap so you can put a drop of penetrating oil in it in case it won’t pull out easily.


    2. If it gets stuck, the best way to pull it out is to insert half the length of a handkerchief through the slide, grasp the two ends and pop it out.

    Absolutely don't do this. I am a brass repair technician and do not recommend this in any way. Sand paper is NOT to be used on valves.
    Sanding your valves will cause them to stick because they will be loose in the casing and so they will be more likely to catch on the side wall. They will also leak more.

    Allied makes a tool (or you can just make it yourself) that is a flat steel bar with a casing shaped half circle milled in it. You just place the bad through the 2nd slide crook and place the milled area on the casing and apply a level motion. Instant slide removal, no risk of pulling the wrong way.
    You can also lightly tap a mouthpiece shank arbor in the crook.
