What shape polishing stones?

[Birddog1911]

Trying to clean up the bottom of the pan on my lock is more difficult than I expected. I'm also dissatisfied with the lock plate. Seems like i cant get the scratchss out as much as i want with wet/dry paper.

After doing some more research, it sounds like I really need some polishing stones to do a good job. I'm looking at a hard and super soft 1/8" square. But are the other shapes important to get as well? Should I go finer than 320 if I plan to fire blue the lock plate?

Thanks in advance.

I use die maker stones and cratex rods. You can find them in different grits. Get a plastic tupperware container and place a magnet in the container along with some lubricating oil like WD-40. When the stones start loading up with material, dip them in the oil and lay them across the magnet to remove the metal. They come in all different kinds of lengths and widths. Ignore the unmentionable.
