A seasonal item of possible interest. This is turned as a series of separate concentric rings using a 6mm 'captive ring' tool (see picture), starting from a disk held between centres. The rings are not captive of course but are held on the lathe - useful to hold them away from the piece with masking tape as they separate, whilst the next ring is made. The larger (~130mm) set in the foreground is of oak and not well finished - done as a quick piece at the club Christmas do! The neater walnut background piece is better finished and includes features like a central tree and hanging bell.
The cleaned-up rings are tied with a ribbon with a knot between each ring. The result is decorative with perhaps an astronomical feel!
The rings are about 7mm thick and could probably be made of any hardwood - they are more robust than they look and quite easy to make. The insides of the rings were cleaned with a knife and sandpaper.
