Need to cut 7.5-degree chamfers
I am trying to make a stave-shell drumset. I've got a PC690 in a table with a straight bit and a lathe.
To make each shell, I need to run a 7.5-degree chamfer down both sides of 24 pieces of wood, cut spline grooves in each edge, connect the 24 pieces of wood into a drumshell-shaped construction, and finally turn the shell round on the lathe. Would I be better...
1) trying to find a 7.5-degree chamfering bit and running the stock through flat against the table
2) building a 7.5-degree wedge and running the stock against the straight bit?
Thanks in advance.
