I used a closer grained wood this time,and adapted 2 dental skew chisels,one to turn with and one as a micro ring tool,can`t remember the name of the wood,but it came from Stiles and Bates,its really hard wood and was sanded with 10.000 grit straight after the skew chisel turning,its 8.5 mm tall,5 mm across,the ring is 4 mm across and 1 mm thick,the stem is roughly 3/4 mm thick.Sorry about pics,forgot to use tripod and timer.
