Now that the shell has been glued and clamped overnight it is ready for the machining process. It is chucked into our machine and rough shaped to a size slightly larger than the finished diameter.
Next the shell is hand sanded progressively through grits 60, 80, 100 & 120. This not only smooths out the shell's exterior readying it for finishing but also dials in the final exact diameter.
Now the shell is taken to the saw and both edges are squared up to the shell and the final finshed height is established.
Above you can see the freshly cut edges that have been squared at the saw and trued on a granite sanding table. Notice the interior still needs shaping.
The squared up shell is then placed into the machine and the interior is rough shaped to the proper thickness which in the case of the Vintage Stave shells is 1/4". It is then cleaned up with a spindle sander and then hand sanded up to 120.
Here we see the finished shell now ready for the re-rings to be inserted.
