A viewer suggesting making a leather burnisher. I was excited at the suggestion as it is another idea to exercise the eccentric faceplate system. Many would leave the blade as a cone or flatten it on a sander. To me, however, it was an opportunity to take the eccentric faceplate system for a spin.
This burnisher is made from cherry about 10 inches long; the bade is about 6 inches; the handle is about 4 inches. The handle contains four grooves to use to burnish edges of leather pieces: 1/8, 1/4, 3/8, and 1/2 inches. It is finished with beeswax and mineral oil.
After turning the handle and its grooves, I shifted the axis by 1/4 inch on the blade end by shifting holes in the faceplate. With the burnisher now turning off center, I turned a taper on one size of the blade, then sanded the blade.
Then I shifted the axis by 1/4 inch the other way and turned a taper on the opposite side of the blade. Sanding the blade is a challenge because I could not touch it directly. I sanded with long strips of cloth backed sandpaper.
