Alright, so last week I found some 320 wet/dry grit at home depot and did some major flattening. Took about 45 mins or so to do the 4K side. I must have gotten that thing crazy out of whack with the norton flattening stone.

However, it also appears that my norton flattening stone is indeed flat. I tested this with a straight age, just as was suggested I do for the hone and it appears to be flat. So my guess is that when using the flattening stone it would be best to place the stone on a flat surface and go through the motions just like you would do when using the wet/dry sandpaper technique, though I have yet to try this out myself. Has anyone used the flattening stone with any success? Any comments on the best techinque?

At this point I feel as though I'd recommend the sandpaper route, pretty easy and cheap, but since I have the flattening stone I'm curious...

Thanks all for the tips!
