Where could I talk to you about potentially sending in a cornet a while from now? 1928 Pan American, all 3 solder joints along the instrument have snapped, and its been extremely tarnished and dented (not too badly dented on the body however, no stuck slides). Instrument came in a near-junk original case that absolutely reeks but doesn't show mold, came with a plastic mouthpiece oddly enough.
Have you thought about investing in a bore micrometer, or a set of machinist's cylinder guages? Thet will tell you if the slide is coned in, or if the receiver is flared out
Your tool is very much like an adjustable barrel lap. They come in a variety of sizes. You can also turn them down on the lathe if they are close to what you need but slightly too large. Just food for thought.
I’m surprised the player didn’t want those dents pushed out. Nice job on making the tools and expanding the slide tubes. Almost makes me want to go back to playing again.
