I am wondering how many turn the base end of their horns? I have tried it, but it has not worked out so well for me. Consequently, I use a rasp/file to even out the base end of my horns and the results aren't as good as I would like. I had two problems turning the base end;keeping the horn on the mandrel, and being able to even out the wall thickness. My chisel tends to follow the uneven wall rather than thin out the thick parts. I seem to need a good bit of material to start in order to turn it round. For the tip or bands, that isn't as much of a problem for me. Any suggestions would be appreciated.
