Actually, I am wondering how thick you reckon the steel rod is and is it mild steel, stainless or spring steel of some sort? I've got a tenor sax with a few dents in it so I may buy a rod of steel...

Oh yes. I agree, this is brilliant. Thanks for pointing it out BaronJ. It's certainly worth remembering for the future.

Dent removal from brass
He seems to support the dent inside the sax tube using a rod whose other end is held in a vice. My question is that if he hammers down on to the outside of the tube ie in the same direction as the...

Yes I understand what you say Baron J. It takes quite a lot of pressure on a dent to push it back where the brass belongs. One of my ideas was to place a nut and bolt at right angles across the...

Dent removal from brass
For dents closer to the trombone's bell the idea is not to hammer on the dent but to press the brass back into place. I did this with what amounts to being an anvil and a press but the anvil took a...

Removing dents from a brass trombone
That's a good idea Baron. It would save having to fill the big hole worn in the water key while providing a support for the sleeve that goes through the key and touches the support posts. I know that...

making springs
Hi Grahame. It is difficult to find a suitable spring for my trombone because it is about 140 years old and they are not made like this one any more. I have already shown a sketch of the spring form...

I have just finished making a small spring as part of the water key on a trombone. I found that it was very difficult to get the exact shape I needed. I bent the metal so often that I thought it...

Much obliged BaronJ. I'll give it a go soon. Meanwhile the key is solid and the 2mmis also solid. If the washers don't impact on the spring they would have to be smaller in diameter than the coils of...

Hi Baron. Yes I could solder these washers but why would I? The gap between the lever and the posts was meant to accomodate the spring. Unless I use a spring which mounts somewhere else. Actually I...

Hi Russ57. Disassemble a trombone? Yes to a degree. The sliders undo from the tuning crook-and-bell tubes and the sliders come apart from each other. Those are the main parts but the tuning crook...

dent removal in brass
Hi BaronJ. About getting soft steel balls, yes I have seen them advertised on the net but I'm not sure what sizes yet. I'm doing an experiment with a 10 mm ball to see how that goes first.

ball on a string?
How would you attach a ball to a string? I suppose you could drill a hole through it and tie a know in the other side of the string. I've answered my own question!

Yes I suppose so but with a ball diameter of, say, 20mm, the increase in diameter of the trombone's bell (where the dent is located) would be about 15mm. So under a flat anvil, this side of where the...

Yes, you're right BaronJ, on several scores. An electromagnet sounds good but an anvil would have to curve in two directions at the same time. Still. it could be done. But I'll try the disc drive...
