I recently had a request to adjust a loose fitting head joint on a Jupiter alto flute. I checked with Curtis Ferree, and he recommended using their H59 tenon expander. They also list two head swedging dies in specific sizes for Gemeinhardt and Armstrong alto flutes.
I don't want to attempt using the tenon expander without also having a method to swedge the head joint in case I enlarge the tenon too much. The Gemeinhardt swedging die is listed as having a 1.030" diameter hole. The Jupiter flute has an outside diameter of 1.024", so the Gemeinhardt swedging die might work. Is there a way to swedge the flute tenon other than using a swedging die?
I may be biting off more than I can chew. What do you think?
