Made from odd bits of scrap walnut and dowel. The discs are around an inch or so in diameter, 2 are finished with mineral oil and 2 with BLO. Tricky working on stuff this small even with midi size tools but it’s good practice. 3 of 4 spin nicely. The 4th (frontmost in top pic) broke off the lathe. I remounted and tried to save it but it just wobbles and falls over.
