HI this is one that I have made. I will post some pics tonight. You will need a file handle and a old drill chuck. The one I used came off an old drill. I kept the shaft that the chuck was mounted on so no pics for this bit I turned the shaft down to 15mm. I then drilled holes in it, I drilled out the center of the file handle to 17mm, mixed up a good dollop of epoxy and filled in the hole in the handle. Then got the drill chuck and worked it up and down in the hole so the shaft and the holes in it got a good coating and then left it to go hard. Its brill for holding parts for buffing.
