A failed attempt *PIC*

Winston
I tried using the yellow 5 micron JacksonLea compound (or, as David calls it, yellowcake), and it was a bust.

I used a modern Stanley block plane blade -- not fancy, and probably pretty soft. First I flattened it on a Shapton Pro 1000 and then Sigma Power 6000. (I made sure to dress the stones with a flat diamond plate first.)

Here's what it looked like. There's a visible line where the texture changes. I'm not sure what that is -- maybe where the heat treatment stopped? Interestingly, the side of the blade is darkened, but the dark part goes up another 3/4" or so. Maybe one line is where it was heated, and another was where it was quenched? I don't know.

I had a soft 3" buffing wheel that I charged with the yellow compound, and used it on the blade this way, for a total of probably around 1.5 to 2 minutes.

This is what the blade looked like after.

I apparently got too close to the edge, but it didn't really matter. When worked the blade on the stone again, I found that only a relatively small part of the center was raised enough to avoid the stone. This isn't enough to really improve sharpening time, and I think it would go away pretty quickly because it's quite shallow. This is what it looked like after hitting a Shapton 12k stone (note that the lighting makes the scratches look a lot deeper than they are).

So the 5 micron compound on the soft wheel didn't have enough cutting power to make much of a difference, and the soft wheel didn't let me control the positioning well enough to make a useful ura. Ideally I'd be able to prevent at least 80% of the blade from touching the stone, and hopefully more. This wasn't even close to that. For this to work, I'd need to use something far more aggressive.
