Here's the outboard honing wheel that I made to hone the flutes of my bowl gouges:
Two 8-1/2" disks of 3/4" MDF, screwed/glued together. Bored a 1-1/4" hole through center, and 'threaded' it onto the outboard spindle. The spindle made it's own "threads"... not deep, but deep enought to hold it while turning and honing.
Outside disk is turned down to fit the U Flute on my Thompson 1/2" bowl gouge.
The inside disk is turned to fit the U Flute on my 5/8" Thompson.
I charged the wheel with black emery rouge, and melted it in with a torch. :fireman: Now all I do is re-charge it once in a while, and it works a treat, honing the inside of the cutting edge.:2tsup:
If you want to make one, when you first get the bead close to the right size (you want it taller than the depth of the flute), stop the rotation and try the gouge on it sitting still.. rock the gouge a little, and the shoulders should mark it for you, then cut it down slightly more. Turn it down til you can just rock the flute side to side on the bead slightly. Once I got it to fit the flute in that manner, I melted the rouge on it.
When I hone it, I put flute on the bead with the cutting edge out a bit from the bead, then, while rocking the tool shaft, ease the tool back just til the rouge begins to curl over the edge... you're done. Too much, and you'll dull it instead of hone it. :o
Now that the glue is set, I think I might take the screws out, and charge the outside flat... it would be a good place to hone the skews....
