    I found a set of instructions from a repair online.
    1. Get a Brass Sheet
    2. cut out as diamond shape.
    3. Solder it on.
    4. Enjoy.

    I wish I could do it.
    But I guess I should go to the repair.
    I thought of spare parts but no luck of finding.
    Poor YCR233S Cornet.

    Greatly simplified instructions, Brass sheet is usually supplied in a hard condition, cut out the diamond, anneal, if the crack is in the center of a bow then the patch has to be formed to a compound curve to fit, cleaned, soldered cleaned afterward and replated if silver. I have made a female mould from a zinc based casting alloy to form these patches for the small slides.

    How much did you pay for the cornet? Is it worth putting money into it? When I was in business only in exceptional circumstances would we do a repair that cost more than half the replacement cost.

    Regards, Stuart.

    Electric tape does wonders. I use in place of band aids all the time, once when stitches would have been the sensible thing to do. Also duct tape-"if you can't duct it then f*** it". Copper is more malleable than brass and is already in a tube shape

    I don't know why I didn't think of that. I know a top pro who's been known to show up with electrical tape on his vintage cornet. Looks like crap, but plays like a dream. These days, you can also get duct tape in a wide assortment of colors and patterns (the snakeskin is especially interesting, but clear duct tape would probably be even better for temporary use until you can get it to a repair shop.

    There's also aluminum duct tape with a paper backing and forgiving adhesive. Look just fine on silver horns
