take a long 1/2in. spade bit and run 2 pieces of 1/2in.x1in. 6in. long weather stripping longways up each side. Leave about 1/2in. past tip of bit so you don`t mess anything up. That will make a 1in. square about 6in. long clip the corners to make it a octagon,rap a piece of 320 or 400 grit wet/ dry sandpaper aroud it, insert and chuck up in a drill on low speed. Works real good and is very forgiving. My camera is on the blink or I would post a pic. but I think you can get the idea. Enjoy,

Get a piece of wood dowel, and cut a longitudinal slot down the middle to suit the width of the sandpaper/emery cloth strip that you have. Put one end of the sandpaper in the slot, then wind the sandpaper around the outside of the dowel - making sure that you wind it in the direction that will not unwind it. A combination of centrifugal force and the springiness of the sandpaper will regulate the amount of material removed. This handy little tool can also be used with the workpiece chucked in the lathe for polishing bores as well. Make a few different sizes for different size bores - 1/4" dia, 1/2" dia, 1" dia, etc.

Take a peice of 1 1/4" hardwood dowel and turn it down on the wood lathe. Didn't have a drill long enough, same problem with a brake hone. And just using a peice of slit dowel wouldn't let me chuck it up in a drill. This was mostly just a turning exercise, but it dd what I wanted it to do. Later.
