I have a question about using greaseless compounds:

I've taken apart two razors and used my variable speed Porter Cable buffer at the lowest speed and a progression of 80-600 greasless compounds to clean/buff the blades.

What I've found is that I've wound up with an uneven edge – i.e a slight frown in one area- twice.
When I work on the blade, I always use a light touch to sweep the blade (edge down) across the wheel from heel to tip. And I've done everything I can to ensure the blade-to-wheel angle and pressure are constant the entire time.

I've repeatedly watched the buffing videos in the SRP Wiki, and I've read everything I can find in the forums, but I may have missed something.

Any suggestions, or maybe a link to the post/wiki article I'm missing, would be greatly appreciated.

I'm very new at this, and I've only been trying this on razors I've gotten for dirt cheap off the Bay, specifically to practice with, but I'd like to refine my technique before trying this on a razor that isn't a 'practice' or 'junk' piece and I'm not sure what I'm missing.


Thanks for your advice!
