Recently I had been asked why bother with JNats on the ep , you cannot work the slurry as it will all run off , blah blah. Well my short answer is that it takes more skill than freehanding , and that the secret is water control (the secret to a Jnat is water control anyways but it is especially important with EP use) , long story short I recently got a Maestro Wu folder in as a Christmas Present for someone else , and of course I had to tweak the edge a little bit. Well a lot actually....
So here we have the factory edge. Coarse , but it is a good coarse edge , nice and even , no residual burr , this is an excellent starting point.
So my first order of business was to do a minor reprofiled and take it from 20-22DPS and knock it down to 15DPS precisely. So I used a shapton 220 , then a 1k. Then I made the hop over to Jnats. First I used an Amakusa , then an Igarashi. No pictures of the edge at this stage sorry. Interesting note was that when I made the conversion to the Jnats I had a sizeable burr. I never bothered to remove it , and by the time I was done with the Amakusa it was gone. Jnats seem to have the tendancy to not form , or form very little burrs in my experience.
Next I moved onto an Aono Aoto , this is the first time in awhile where I have felt an edge and been pleasantly surprised. This would be a great all around edge. Nice and refined yet still "toothy".
Then I moved up to a Meara.
Then a Yaginoshima Asagi , she is really starting to perform now.
Then I went to an Ozuku Asagi , this is a great stone. I raised a bit of mud on this stone with a 1200 atoma (well broken in) , worked that for 20 minutes. Then I took it one step further , I doped the stone with some 0.125 CBN and took it beyond what the mud could do on its own , I worked the supercharged slurry for another 10 minutes and here is the result.
This was a fun experiment for me , and my findings reflect those already shown by Dr. Matt on youtube. He does some excellent videos and I would advise everyone to watch them.
Thanks to Bullman for selling me the knife , it is going to a good home.
Thanks to Ken for selling me the stones , and always being around to talk to and critique what I am up to. I have learned a lot from you and you are a true friend.
So anyone who says you cant use a Jnat properly on an EPA or EPP , I say phoeey on that.
