I posted this project some time ago, but I have made one improvement and a video of its construction and use. Newcomers who have not seen it may be interested as well. The only real problem I had was that the plastic disc holder got too hot in the wooden sleeve that it rotated in. I had used it on high speed to embellish one of my bowls with dye. Worked OK at the lower speeds used for tool sharpening though, especially with some lubrication, I hadn’t thought of that at the time.
The modification that I did was to find a piece of steel tubing to fit over the spindle part of the disc holder and epoxy a short piece on.
Then drill two lubrication holes, I am adding white lithium grease from a spray can. I also put some right on the sleeve and insert it back into the hole. Once the grease soaks into the wood it should be good to go forever.
To modify the food processor and give the disc holder more support I made a wooden base for it.
Start by cutting a wooden ring that fits around the base, make notches for the indexing bumps,
Then glue it to a thicker block of wood of appropriate thickness, leaving room for the top bearing block. Shape the edges to a 45 if you choose and drill a hole in the center. To attach the bearing block, you have already drilled it to accept the disc holder, put the disc holder in it, with the base on the machine, glue it to the base. Clear as mud. eh.. The rearing block with the disc holder in it slides over the spindle and centers it. Clear as water now, eh..
Then just make some wood discs to fit on the original blade holder and you are ready to go, sticy back sandpaper can be attached to both sides. One can make their own by cutting 6 inch discs and spraying with and adhesive. I also used a 6 inch grind wheel for more aggressive shaping and honing. Just had to make a plug to center the wheel using the small peg that sticks up.
All in all this has worked well for me and it has been the first time I have had nice sharp edge on my tools. Ther are many good sharpening stations out there but this one is free. You just have to jerry rig the safety switch to get it to run
It does put a fine edge on hand tools without overheating
If interesting seeing how I made this and how it works take a gander at the following video.

Thanks for looking, hope this post gets the wheels turning, just don’t draw blood with your sharp tools. Comments and suggestion appreciated.
