My question now is do others check their angle between grits on the diamonds? I’ve done that on some knives and have found variance nearly as much as 0.4 degrees or so. Would the SWAT jigs be a quick remedy for this or do you not worry about it? I’m using the old arms by the way and it can get tedious tightening and untightening. I get pretty good polishes but have wondered if the angles not being exact have led to more scratches remaining. It’s difficult to check the angle on the ceramics since obviously there’s no metal to stick to and they tend to want to rock a little bit. On the strops I’ve been lowering the angle 2 degrees on the past several knives I’ve done. All the edges are laser sharp even when not checking the angles. The 1k grit edge on my more and more broken in stones leaves a satisfying, sticky sharp edge that makes you all giddy inside. I’d love to see a video demo of the swat jigs with an angle cube and just how they work in general.[/quote]
Great job man! yeah it definitely turned out well! One thing I like to do when the transition is rounded out on tantos is to take your lower grit stones (or belt sander) and re-shape your tanto tip/transition by grinding perpendicular into the edge. Then you can sharpen for a nice clean tanto transition. Now, on to your questions…
I would say that after you check the variance in your stones one good time, you won’t need to check them every time. My diamonds tend to be very uniform in how they were mounted, but others (like Tom - tcmeyer) have reported that they were mounted very “crookedly” to where one side was higher than the other. But the plates themselves were designed to be consecutively thinner so that it ever so slightly widens your angle with each transition (I am talking a very minuscule amount here). And yes, if you are wanting to adjust the for the width of your stones the SWAT is something you need to use (for speed’s sake)… but I find that I don’t need it because I know how my stones perform (even though I have it).
I will have to see, but maybe I can knock out a video soon of what you are wanting. Oh, and one of the keys that I have found with the scratches is to avoid the 100/200’s if you can… if not then spend a LOT of time with the 400’s to remove those deeper scratches, or they will reveal themselves at higher grits (they are very deep).[/quote]
Thanks for the kind words. I sharpened a Contego tonight and will post pics later, but I again checked the angles between stones and even though you said they’re designed to make a wider angle, I found most every stone change to get more narrow or acute than the previous angle.
I sharpened at 18 dps and I found the variance to be as much as half a degree. Got readings of about 18.5 degrees and got some at 17.6 or so. Sometimes less than 18 on the left hand stone and .3 degrees or so wider than 18 on the right hand stone at the same grit. The ceramics were the biggest variance as they were about 17.5 degrees. I guess my question is why do I only need to check the variance once? If I’m trying to get a consistent 18 dps throughout the diamond stones then I still have to put the cube on to readjust. Sorry if I’m misunderstanding.
I wouldn’t mind seeing a video on the swat jig if you ever get the time, and I’m surprised that there hasn’t been an official video demonstrating this accessory. On the Edge Pro you have the drill stop collar trick that makes changing stones a breeze and something like this would be useful on the WEPS. I’m not sure if the swat jigs will even work with the old Gen 2 arms.
Now for a Contego pic. I tried stropping at one degree lower rather than two this time just to see. This thick blade turned out to be one of my best edges period on this system in terms of polish and sharpness. This thick blade was whittling hair and slicing through phonebook paper with fast swipes like it wasn’t even there.
