Why does my 220 stone cut so much faster than the 120 on the edge pro?

My 220 cuts like crazy, but I swear the 120 hardly cuts at all. It feels about the same as the 1000. Why is that? I can't even use it because it hardly does anything to the blade.
 
Put some playground sand on a piece of concrete and rub the 120 on it for 30 seconds to a minute. It just needs coarse lapping. Carbide grit on glass works a lot better, but the first way is something you can do right now.

Thanks. Is there a reason it came so smooth? To the touch it feels no different than the 1000 grit stone, while the 220 feels very rough.

It's a Silicon carbide stone, just lap it real quick.

That stone doesn't need a lot of pressure to work, less is better.
 
OR it's defective like quite a lot of use received theirs.

a couple forumite had the same issue and nothing made the stone cut including free SiC powder, 40 grit SiC paper, 120 grit dmt ... the stone just doesn't wear at all no matter how hard you try. if it's the case contact ben dale.

Ben Dale won't acknowledge the problem.

I've called Mr. Dale numerous times with questions. I've never had him fail to acknowledge , or correct a problem, or to use as much of his valuable time as necessary giving me sharpening lessons over the telephone.

So what does he say about this problem? He stopped answering my emails after he told me to lap my 120 stones and I did and they cut just a little bit better but still way slow.

So my 120 might just NEVER cut? I rubbed it on the concrete outside and it might be a LITTLE rougher, but not much at all. It's still very smooth and cuts very, very slowly.

Did you use sand? that is very important. Concrete alone, even broom finished, won't work. Smooth concrete and good sand are what you are after.

This is the first time I've heard an EP product doesn't work, or that Ben Dale didn't bend over backwards to please or help a customer.

I bought the SiC as per Ben's initial suggestion. It made a little improvement but not really enough to make setting a bevel in less then an hour and more like two to three hours with S30V or better steel.

that is very true. i've had a problem with my diamond hones, the parcel didn't want to go through us custom, don't know why. ben Dale handled it very well by mail, he finally offered me to ship via usps tracked and insured for free, the package was 40usd in value, i wonder if he made any money here .

honestly i haven't even tried to bother him with that as i thought that the diamond stone would be better anyways ... that's the case, the 400 eze lap outcuts the 120 grit stone easy. i can't think about how fast a 120dmt could be in such a controlled device.

I did not use sand. I'm probably just going to buy a stone leveling kit and if that doesn't work I'm just going to buy another stone. The fast reprofiling is one of the things I was excited about with the edge pro so I want to get a stone that cuts fast.

Can anyone tell me what adhesive is needed to mount the stones and also how to get old stones off the blank?
 
3M - 77 is the contact adhesive that probably works the best. It's what I use, and I've never had any problems whatsoever. I've used (I'm not sure of the maker) 357 with good results too. 3M makes another spray that is 90-something that isn't recommended because it's too strong and hard to remove. I haven't tried to remove the 357, so can't say it's easily removable. I think Ben uses 77. It's strong until it gets hot (like 200*F),which makes removal easy.

Singularity 35, I'm sorry and surprised about your experience. That blows me away. I've had good success with the 120s, but I went to 2"x6" DMTs, and never looked back. I've never had any trouble with an EP stone, but there are better stones easily available now. Kinda pricey, but definitely worth it IMHO. I use XC and F DMTs, and Choseras and Shaptons now. Tom @ Jende Ind. (http://www.jendeindustries.com/mm5/merchant.mvc) is super great to work with for me. He may send you over to Ken Schwartz, who is also a great guy, and the one who actually does the stone cutting. I'll tell you right up front not to expect speediest delivery. Ken is super busy.
