Its a while ago but the file sections would have been about 4″ long X 1/2″ wide X 1/4″ thick, the wheels top and bottom proberbly 18″ dia, It would be used in a similar way to a linishing machine/ belt sander. The only lathe they had at the time was about 6ft between centers, with 18″ chucks, in very good nick, but just a little on the large size.Ian S C
