Honing discs for bench drill

You may have seen that some whetstone manufacturers offer profiled honing wheels for their machines. They are made of leather. They aren’t cheap!
Medium density fibreboard seems to have the same density, take up the polishing compound just as well and are cheap as chips to make. Even if you don’t have a holesaw, if you run the blank on an arbour in the drill, it is easy to shape the spinning disc with a rotary rasp, even a hand rasp.

You must run it at a slow speed, with the edge away from the direction of rotation, as I am sure you will recognise.
