This allows gripping in a four-jaw scroll chuck for drilling and ensures that the inside and outside of the spindle are concentric with each other.
A much better arrangement is to do all the internal work first, then grab the bore in cones and turn the outside. Fisch’s Pepper Mill Boring Kit for lathes (inset) provides drill bits, extensions and a Morse taper.Ī mistake that most turners make is to turn the outside first. The bottom style (item 35401) makes a mill in which the top part revolves around a relatively short section on the bottom. The shafted model at the top (item 32708) makes a traditional pepper mill from 5″ to 9-1/2″ tall with a rotating cap. (The closer to the equator a tree grows, the more likely its wood will be toxic so it can ward off insect attack.) Rockler’s two CrushGrind Mill Mechanisms have ceramic grinding cones that stay sharp and grind well. Tropical woods also work well but may pose toxicity problems for some people. Any wood can be used but a dense close-grained wood such as maple or cherry work best.
You will need to start with a wood billet that is 2-1/4″ to 2-1/2″ square. For this article I picked the Rockler CrushGrind Mechanism, which grinds superbly. This project absolutely requires the purchase of a grinding mechanism, and it also demands that the mechanism fit superbly in the wooden body and cap to work well.
Over the last forty years, I have turned a good many pepper mills using a variety of grinding mechanisms.
