I was wondering what the folks who run the TimberAx head do to sharpen their knives. There has to be a better way than what I am using. I touch mine up two or three times on the machine with a side grinder and then take them off to sharpen and reset the angle. I cannot find a machine shop in the area that will do them for what I consider an affordable price ($450.00 to mill 12 -9" and 2- 4" knives). I currently use a 12" table top disk sander with a 40 grit disk and the table set to the correct angle. I keep them cool with a bucket of water so as not to over heat them. It takes about 15 to 20 minutes per blade to get them sharp at the correct angle. Any help or suggestions would be appreciated.
As the knives have gotten older they don't stay sharp as long. Has anyone had any experience re-hardening the blades, or case hardening the flat side of the blade so as to make them self sharpening. Years ago my dad and granddad used to case harden the flat sides of rotary mower blades, plow points, etc. to make the blades self sharpening. They used a case hardening powder.
I do have two sets of knives so I can operate during the day and sharpen at night.
