Alright, I realize that many people guard their information, and I'm not asking anything specific. Just wondering about the machining technique to bore the inside diameter of the trumpet. Do you all use a drill chuck in the tail stock with a tapered bit? I'm trying to learn to make trumpets and just curious. I turned one and drilled the center out on my press using successively smaller forstner bits but the result is ugly and inefficient. Just curious if y'all might lend some advice. Thanks in advance!
