Saving an Olds Recording Trombone
Some of my favorite trombones were built by the company Olds. They had a wonderfully deep line of high quality instruments and this one, the Recording model, is one of the good ones... but this one has been badly damaged. A BIG dent was "installed" in both the outside and inside slide tubes. Getting the dent out of the outside slide is easy but is it even possible to remove them from this very unique inside slide tube? Let's find out.

      @@repairmasterclass As I mentioned I’m a professional musician. I have played in a symphony orchestra for 40 years here in Chicago. Your video seems to demonstrate how to change strings using the geared pegs, which is fine however a player would never take all the strings off and then have the bridge fall over because they would have to have it reset by a repair person-players would change one string at a time and then move onto the next string. Naturally the bridge moves around clearly that happens, and occasionally you need that adjusted but if you’re a player you simply wouldn’t take all of the strings off and chance the sound post falling over. A repair person might do that, yes.

  • @mellissadalby1402
    @mellissadalby1402 Před 2 měsíci

    I would be concerned about removing all of the strings at the same time, such that the loss of tension on the top plate could loosen the sound post and if the wood is really dry, the sound post could fall over, which turns a rather quick job into a longer job. I'm sure you know what you are doing, but I would be a bit more conservative in my approach. Is that excessive wear on the fingerboard such that it could stand to be planed a bit? Is that a groove under the A string or just silver residue from a silver wound A string?

      Yeah… the fake Wittner are a mess. There are two options for you: 1) use a pair of flare nose pliers (and only flat nose) to slightly squeeze the string just above the ball to help it fit the fine tuner. 2) Use a screw driver to gently pry the fine tuner open - be careful here, there is not much room for expansion but it can be done.

    • @repairmasterclass
      @repairmasterclass Před 3 měsíci

      I’m afraid this is one of those applications that you really need the right thing. The reason hide glue has been used for centuries is because it works exactly as needed, including the ability to get things apart when that becomes necessary. Typical wood glue is next to permanent. Don’t use it. White glue is almost as immovable so don’t use it. Super glues also fall short. Order some glue or take it to someone who does this for a living, they’ll have it and it’s not an expensive repair.

Unless you have a split E mechanism installed on your flute (the G key is split between two independent keys and not just one fixed key) then the repair is beyond what I can help you with here. Sorry. Go buy groceries like chips, health bars, fruit, root beer, chocolates, etc, and take them with you to the repair shop. Start by placing the chocolate on the counter, then your flute.

And in addition to this bridge I also have Il Cannone Cello Warm & Broad strings.So, the resaults for the sound are better. but overall I find the hight of the bridge pretty high for what i used to play. and the sound post is bigger diameter now. For a student cello i don't know if this is the optimal set up. They told me that the distances for strings and height have the correct measurements. The only problem is that i get a lot of wolf tones.

    • @repairmasterclass
      @repairmasterclass Před 5 měsíci

      Hmm... If I understand your issue correctly, this can be a difficult one. If you're referring to the notes of B and C on the staff, these notes can involve a long air column and lots of places for small leaks to pile up. Typically this has to do with the F#-C# key on the bottom joint and can be tricky to adjust correctly and remove any lost motion. If you're referring to B and C above the staff, then I would think you have the screw at the G#/A location a bit too tight and the G# is not closing all the way. You want a little bit of movement of the A key before it hits the G#. Loosen that screw and see if things improve.

    • @repairmasterclass
      @repairmasterclass Před 5 měsíci

      Sorry for my delay, I was on vacation. There are a few reasons this could be happening. 1) The screw at the D key (could be on top and easily visible or under the key) could be the issue. Use a feeler gauge and adjust accordingly. Very, very small turns of this screw make big changes. 2) The D# key on the foot joint could be leaking. Use a feeler gauge to test for a seal here. 3) The D key could be leaking. Take a look at these possibilities - learn more about how to do this with the Emergency Repair Guide available for free on my site - and if you're still having issues, take it to a shop you trust.

    • @repairmasterclass
      @repairmasterclass Před 5 měsíci

      If you've been turning the screw several times with no change, I'd guess there is another issue at play. The screw may be broken (this happens a lot with plastic screws) or something else. Start by trying to take the screw out - so turn it counter clockwise and extract the screw (don't drop and loose it) to ensure the screw is not broken. If it comes out, it will go back in. When it's in, make sure the G# arm is not bent to the point the screw does not contact the A. If these don't show you the issue, take it to a tech you trust or ship it to me to take a look at.

      The inside slide of a trombone is most often a brass tube that has then been chrome plated. In some horns, they use a nickel tube. The trick for sourcing a tube locally is the stocking - the bottom 6 inches or 15 centimeters has been expanded to within .003 to .007" (.07 to 1.77mm) of the outside slide. This is done to make the trombone, with lubrication, air tight. That's difficult to do by hand... Reach out to the manufacturer or any of the many suppliers for some help getting a replacement tube.
