This project uses a 12 mm or 1/2” thick aluminum plate or round bar to create a hand wheel. If using cutoff round bar material you may need to square it up in the lathe first. Drill through the center of the material with a 5.5 mm drill and thread with 6 mm tap. This serves to bolt the aluminum to a piece of material that can then be clamped to the machine bed. When complete the center hole can be drilled or reamed out to the size required. The NC file provided will machine the basic shape, other details can be done manually to one’s own requirements.
