This is what happens when you have hours upon hours sitting in the cab of a mulcher to think of ways to make your life easier. I figured there must be a way to keep a factory like edge on the teeth/knives and came up with this. This is a crude prototype thrown together in a hour. It holds a 8" bench grinder. The angle is adjustable, and gravity keeps pressure on the tooth since the grinder slides on the 2 long bolts. It uses the tooth bolt and the bite control discs on the drum as reference points to assure a consistent angle. If we ever get another slack day I'll make everything on the mill and clean it up a bit, but for now it might be ugly but it works. It takes less than 10 seconds to move the jig to the next tooth. Once any large dings in the tooth are smooth you can walk away and come back in about a minute to move it to the next tooth.
This is a freshly sharpened tooth that has 63 hours on it.
