    Thanks for links that was really interesting, so I guess the use of different thickness' is what really might separate one manufacturer from another and what makes every trumpet sound different

    That would be a vast oversimplification. Different alloys, different thiknesses, different heat treatment, different alignment of parts, different soldering jigs, etc., etc., ad nauseum. The number of differences and the way that they are handled all contribute to the making of a superlative instrument. Empirical testing of a LOT of them while having an experienced trumpet player listening and trading off with you, so that you can listen is the only 'fairly safe' way to select a horn for yourself.

    Well guys would be safe to ask what is the thickness of the raw material brass before it is bent and shaped for a Bach Strad 37. This may sound redundant but I am curious what the dimensions of the raw materials before they are shaped.

    Thanks,
    Jim

    See if you can measure the gauge at any point where the material is straight - as soon as a bend is applied the thickness will be reduced (a tiny little bit). I reckon you would be hard pressed to measure the reduction in material thickness, even in a bend, without specialist measuring equipment, mostly because the bends are generally gentle in nature. The place where the thinest material will exist, I think, is where the raw material has been stretched over the bead wire, but you'd still be hard pressed to see the reduction in gauge due to working the metal.

    As a generalization many bells are made from brass that is about 0.020" or 0.5mm thick. But that is only a starting point.

    Guys I guess I am asking this wrong I understand that the metal will change thickness as it is worked and bent but my question is what is the thickness of the material before any work has started. Remember I am asking about a Bach Strad 37 but maybe you guys know an acceptable range that most manufacturers use.

    Sorry,
    Jim
