I got this idea after watching a video for the Razor Sharp Edgemaking system and wanted to try it. Their system uses paper wheels. I reckoned, why not something like MDF?
The hardest part for me would be making a wheel without a lathe. I opted for the tried and true table saw with a sled.
Drill a hole roughly in the centre to accommodate a wood screw. The screw should fit loosely in the hole
You can apply some more compound as you use it.
It is very important to note that the wheel must always move OFF OF THE BLADE. Do not risk catching the blade in the wheel.
My abused chisel went from dull to shaving sharp in seconds. I can't wait to try it on some knives.
Of course this is only for the finest honing. If you've got nicks to deal with, you'll have to get it to a near wire edge first.
Second hand grinder (garage sale) $10
Polishing compound $0.10
Experiment Grand Total: $11.10.
This is really hard to photograph, but what you are seeing is the reflection of the secondary bevel. The words "ZOOM LENS" can be seen in reverse. The edge is has been mirror polished by the compound.
CONCLUSIONS:Super fast and inexpensive. A cared for blade can be touched up in only a few passes. Amazing bargain.

This is the polishing compound:
