    I recently bought a Selmer Paris 1905 Sigma. I am having trouble with the main tuning slide leaking water. The Sigma tuning slide surfaces were polished and finished unlike the raw brass that I have on my other horns. The slides worked smoothly but seemed to be a looser fit than other horns. Are my Sigma slides typical for Selmer Paris trumpets or I do I have a lemon?

    I have tried Giardinelli, Superslick and Hetman 5 tuning slide lubricants but they all leaked eventually. Hetman 7.5 worked the best. Can anyone recommend a tuning slide lubricant that would work better than what I have tried? Thanks, Jim

    I use lanolin on mine. No leakage. No complaints about the Sigma at all.

    If your tuning slide legs are loose, they can be replaced at a relatively small cost, probably less than a hundred dollars.

    You'll want to have one of the better-known shops do the work.

    Anhydrous lanolin. Used to be able to buy it packed in 35mm film cannisters at pharmacies dirt cheap. As long as the slide isn't moving by itself, the water leakage is not a huge issue. If air leaks, yeah.

    A good tech can expand the inner slides, if necessary, at a surprisingly nominal cost.

    I'll second the usage of anhydrous lanolin which I can still buy at health food store here. Beyond that if there is a water leak, I'd wager there is also an air leak.

    Several of my horns leak a little water from the top leg of the tuning slide, unless there are bubbles appearing or hissing it is of no consequence, the pressure is so low inside the horn that the water will maintain an airtight seal. One of these days I will get around to measuring it.

    I have found the Lanolin my repairer has given me (he has a 20 litre drum of it) to be temperature sensitive, goes hard in the cold and soft in the heat. I use an Ampol Red grease on the tuning slide, 1lb tin $0.45 40 years ago. It will see me out.

    Regards, Stuart.

    Easily done for free. Grab a trombone mouthpiece, insert into the slide and pound gently. Ta-da!

    I'd prefer to have more of the slide expanded to distribute potential wear to a larger area than just flaring the end would do. I would think that the result of flaring the end with a trombone mouthpiece would eventually either be thinning of the tubing at that spot, or that the fix wouldn't last long. There also might be a chance that the flared end might dig into the outer slide, scratching it since there would be less support along the rest of the slide, and the slide would be cocked ever so slightly. Yes, we're considering very small measurements, but the principles still apply.

    So... then... just get the slide tubes replaced!

    Not all that difficult...
