Funnily enough
Gary done as a batch process it is no more boring
(sorry) than a bowl etc. because a finished item does not appear until near the end
1. Prepare a batch of rough cylinders approx. 50mm dia on bandsaw.
2. Turn up cylinders (long enough for two rings) all to same nominal external dimension. *
3. Bore all central holes to same size and sand bore.
4. Part off into two rings of nominal length.
5. Size all rings to same length. ** and sand ends.
6. Turn up tapered jamb chuck spindle to mount rings on.
7. Mount each ring and turn outer shaping and sand finish. (not too tight or rings may split)
8. Immerse rings in diluted cellulose sanding sealer, remove and drain until dry. (fixes any stress cracks)
9. De-nib with webrax.
10. Reduce diameter of jamb chuck spindle by the thickness of a layer of soft cloth.
11. Attach soft cloth to spindle with spot of CA glue.
12. Apply wax to each ring in turn and lightly hold on start of jamb spindle to polish inside of each ring from both ends.
13. Push ring firmly onto jamb spindle and buff outer surface with soft cloth.
Notes:
* I did this by drilling an 8mm hole through and mounting them on a bit of 8mm studding, nut and washer held in chuck, quicker than mounting between centres and provides a start for boring process.
** reference off face of chuck.
