A pictorial :)
The Cad of course
The CAM
Cutting up the huge wax block
Lathing it to size
Transfer from lathe to mill
Start roughing
Start Final outside cutting
Finish outside
Sacrificial wax holder for bell
Cut to fit bell
Wax welded into place
Interior of bell being cut
by this spiral path
All done, remove bell
And the final piece! ready to hang on ur bike!
