Today was a very frustrating day.  I worked on soldering a new mouth pipe to a trumpet.  My casing to mouth pipe brace went on beautifully, but in the process my casing to bell brace came loose.  I cleared the excess solder, and it was still aligned well so I decided to reattach it before continuing to install my mouth pipe.  When I finished reattaching the casing to bell brace, I noticed that my first casing to mouth pipe brace had shifted.  Needless to say, I pretty much went through this whole process again, unsoldering one side as I soldered the other.  By the time the day was over, neither brace was attached, and I had already solder the casing to mouth pipe brace three time and the casing to bell brace twice.  Tomorrow John (John Huth, my instructor) is going to help me.  We are going to solder the mouth pipe on completely before soldering the casing to bell brace.  He thinks that if we lay the trumpet on the mouth pipe while soldering the bell brace it will be less likely to shift out of place.
