Hi, I just got a new to me Edge Pro and I just received my order of Congress stones as the ones that I got with the EP were too thin and un-even from use.

My Congress stones include:
120 "regular"
240 Moldmaster
320 Moldmaster
400 Moldmaster
600 Moldmaster
1200 Superfine

I practiced on the old EP stones by setting the angle after each stone and I got what I thought was a decent edge and was able to raise a burr.

Fast forward to when i tried the Congress stones. I soaked them in water and then re-profiled an old Mora knife that I had (30 degrees inclusive). I proceeded through the grits and when I got the the 1200 superfine it basically shaved off slices of the stone with every pass. I measured the thickness of each stone with my caliper before i started and they were all within acceptable tolerances.

Upon further examination I realized that I had a wider bevel on one side of the blade than the other. Could this be why it shaved off so much of the 1200 stone?

Also, how can I ensure that I am creating the same width of bevel on either side of the blade?


I think I might have softened the stones up a little too much by soaking them in water during the whole re-profiling process....Would this have any effect?

Hopefully someone has some tips on how I can improve

thanks!

Well, using the congress stones adds a fair bit of obscurity to your question, actually, since the stock stones are made by Boride. Just hazarding a few guesses:

1: Your 1200 stone was thinner than the others, changing the angle. Sharpie and the drill collar can really help that.

2: Too much pressure, once you get up to the finer grits, just the weight of the arm alone is more than enough, sometimes almost too much.

3: Count your strokes to keep the bevels even, and if you need to, use your caliper to check that they're staying where you want them.

If you don't have an angle cube already, it's a worthwhile investment, as is a good diamond plate for the initial profiling steps. That EP is capable of edges so sharp they'll frighten you, it just has a bit of a learning curve involved. Good luck!
 
Thanks for the reply.

I agree with all your points. I used way too much pressure on each of the stones and I didnt do a god enough job in trying to keep the bevels matched up.

I have a drill bit collar on my list of things to get along with a flat piece of glass to flatten my stones.

I downloaded an angle finding app for my iphone and I've tested it on some known angles and it is extremely accurate.

I will re-check the 1200 to see if it is thinner but once I get the drill collar I will be able to eliminate that problem

Thanks,

I tried the superfine,,,, if memory serves me it was just too soft to use. Even trying just a quick spray of water, it would wear way too fast to be effective.
