Turning turkey calls
I just got into turning and am trying my hand at making turkey calls. They're essentially a shallow hollowed wood pot with a slate, glass, or metal surface that you use a dowel rod-type striker on to make turkey sounds. Trust me, it is frustrating.
I'm having some troubles, so let me describe how I'm doing it in hopes of getting some more experienced peoples' ideas of a better way...
1) Cut 5/4 material into an octagon about 4" across.
2) Turn it to round between the pointed centers on the lathe
3) Part it off at the tailstock side as smooth and flat as possible
4) Remove the nub from the parted side with sandpaper
5) Using double-sided tape, adhere a dovetailed tenon on the flat parted side, chuck it in the chuck.
6) Part the top rim nice and flat, and part a ridge to support the calling surface around the perimeter.
7) Using a fingernail grind gouge, hollow the cylinder out leaving about 3/16" thick sides and bottom
8) Sand everywhere but beneath the tenon to at least 400 grit
Now here's the challenge...
I want to be able to finish the turning on the lathe with CA, wax, Huts, wipe-on poly, or other finishes. But, I can't do it with the tenon still installed.
Anyone have any ideas on how to do this more efficiently? I tried a pen mandrel through the center hole I drilled but that failed miserably. I think that I might be overlooking something obvious, given my newbie turner status.
