POWERED SCAREY SHARP SYSTEM
Adding a motor makes this a sharp idea.
SHOP OWNER: Dave Sloane
LOCATION: Edmondton, Alberta, CANADA
A few years ago, I read an article about the scary sharp system of sharpening chisels, etc. I decided to build a powered system using an old furnace motor and plate glass disks mounted into a dish-shaped wheel driven by belts and pulleys. As the motor was a two-speed fan motor, I decided to set it up with switches to run at two speeds and reverse.
I soon found out that all of this was overkill and all I really needed was a dish that rotated at about 200 RPM in a clockwise rotation toward the chisel holder. I mount varying grits of sandpaper to the glass disks with spray glue starting at 80 and work down to .05 micron.
For final honing, I use a felt wheel and jeweler's rouge, which is actually green, and I have never had tools so sharp in my life. I also built a jig to hold my jointer blades and I can now remove them, sharpen them, and have them back in service in about an hour or less, if they aren't too badly nicked.. . . Dave Sloane
