This is the finished ring. It is made out of boxwood and mahogany
veneer. It's a U.S. size of approximately 10 1/2 with an internal
diameter of 20,8 mm.
The basis of the ring is cut on the bandsaw out of a piece of boxwood.
The blank is then glued with CA glue on a piece of wood turned
to fit the jaws of the chuck. The wood is glued in a faceplate
turning orientations (like a bowl). This gives the strongest
grain orientation for a ring.
The assembly is then mounted in the chuck and roughed out using
the bedane; hold with the bevel down, this tool acts as a straight
scraper.
The internal diameter of the ring is marked on the spinning lathe.
The external shape is cut with the bedane, now hold with the bevel
in upward position; one could also use a skew chisel or a spinning
gouge.
The next step consists is creating the recess in which the veneer stripe
will be glued; this operation is made using a narrow tool like a parting
tool.
The ring is then hollowed with the bedane in downward position.
In this specific case the position is relatively higher than the
median axis to avoid that the botttom of the bedane hits the work.
The diameter is periodically checked with a calliper until the exact
diameter is reached (here 20,8 mm).
The width of the veneer stripe is determined by the tool used to
create the recess.
