Rummaged to see what we had to make a copy of Tubal Cain's version, and made one up out of some 1/2" Al tube, brass plugs, neodymium magnets etc. Seems to work very adequately. Also - copied a simple edge finding idea for the mill, from DoubleBoost's channel - press fitted a small bearing onto a short piece of 3/8" drill rod - once again, simple is good. |
