    What temporary procedures? It seems to me that the only proper way to fix it is to let a professional have at it.

    Which horn is it? Which slide? Tell us more and we may be able to help.

    Regards, Stuart.

    My Yamaha YCR233S Cornet
    My tuning slide and my 3rd slide.
    Luckily my 1st slide survived.
    Tuning slide had 2 cracks and my 3rd slide has 1 crack.
    All of these aren't big cracks around 3mm maximum.

    A quick look on ebay shows a couple of YCR233 cornets for parts, you may be able to retrieve slides, could be cheaper than repairs and give you something to practice repairs on.

    Regards, Stuart.

    Can't believe it was a good horn! Whatever happened to that bell you had? To me if they play with small dents here and there then leave 'em be

    I think this video might be the source of some of the confusion, from 3:19 to 4:05 it demonstrates the bending of the tube with the bell during the manufacture of a new trumpet. 2 things that should be noted here, they use water that has been mixed with soap, and the soap acts as a lubricant and might keep the ice from cracking the metal tube. The other factor that is not mentioned is that the tube had been annealed before bending, I could tell due to the color of the tube in the area of the bend. Annealing softens the metal so that it can be more easily formed, and the forming process will harden the tube in the area of the bend. One of the characteristics of a copper alloy, (brass is a copper alloy) is that it work hardens and can be annealed by heating it and letting it cool. Work hardening means that as you bend or hammer the metal, it becomes harder but more brittle, so it sometimes needs to be annealed after being worked.
