Got it!  Thanks.  Don't know why I couldn't find it.  Now I see the plates are used for grading mostly, rather than truing, although Vadim states the stone can be graded 5 times before having to true again. 

Somewhere, but I can't find it, I seem to recall Vadim demonstrating using diamond plates to true the SJ-250.  Do you recall anything like that?  Rather than the stone grader, using different grits of diamond plates makes sense to me.

Also, I've read that the SJ 250 should be trued and I've read that it doesn't need trying. Which is it?

When sharpening chisels, should the SJ 250 be used trailing edge, turning away from the edge?

Ken, I'll be picking up the TTS-100 today.  I see it's made for turning tools?  I don't have a printer to print your projection jigs.  Do you have a site where I can purchase them?  And, great tip on squaring up the chisel. 

So has anyone noticed this...when SE77 is adjusted to give a square edge, the chisel looks skewed on USB no matter what angle I look at it.

Thank you. First time seeing the TTS 100. I'll look into it for sure. Is it always such a hassle using the SE 77, to get a 90 degree edge on the chisel or am I doing something wrong when I butt the chisel side up to the stop?

[so I assume it's not a one time adjustment for all chisels]

Well, I ended up sharpening two chisels and they came out great.  To save time and effort, I flattened the backs on the 250 diamond wheel, then went on to refine them manually on my ceramic stones.  Preparing for the bevel, I did have a time adjusting the SE77 to produce 90* edges and had to do it for each individual chisel, so I assume it's not a one time adjustment for all chisels.  The bevels were worked on diamond wheels 400, 600, 1000 and 1200 grits and hopefully, burrs were removed manually on a leather strop, as I am not yet confident enough on the leather wheel to not accidentally round over the edges. 
Can Calcapp be used for chisels?  I used the supplied angle finder, however I'm not sure how accurate it really is.

I think my biggest concern is using the side of the stone to flatten the back of the chisel.  I know how much care must be taken when doing that by hand, so it's hard to imagine holding the chisel perfectly still with all the forces of the turning wheel acting on the it.  I know what a perfectionist Vadim was and is, so I was hoping he had made a chisel video demonstrating his techniques, including how he would remove the burr and polish. 

Hi all, I'm looking for a Knife Grinders vid on chisel sharpening.  I have many of the Knife Grinders suggested accessories and would like to use a more advanced method of sharpening my chisels, rather than the tradition methods. Thanks for the help.

You might try getting a wheel balancing system. Here is one example:  https://oneway.ca/products-category/sharpening-grinding-jigs/Balancing%20Systems

Will this cure a wobble in the wheels?  Paper wheels wobble.

Well, the saga continues...I ran some tests with the slow grinder and was really have a problem with balancing out the paper wheels.  I took some suggestions and got a full speed grinder, well actually a variable speed, anyhow, it works much better.  First, I'm able to adjust the wheel mounting to get a much less wobbly wheel.  Secondly, at full speed, the wheels seem to smooth out a lot.  With the variable speed, I'll be able to slow it down a bit and find a happy medium between smoothness and heat reduction.  In addition, I was able to get this Delta model grinder at a greatly reduced price at Lowes.  I did have to readjust everything, but I think this will be a better setup in the end.

Thanks for the link.  Lots of good info there.  From what I've seen on KG, he used a few different machines, like a Vicmarc DS 200 S and the Optimum, which are both 2800 rpm machines.  I also gleaned this from the link...

From what I've seen, he was using Optimum PSM 200 polishers. From what I could find, they are 2800 rpm. Also, in a thread, he's talking about his polishers being 2800 rpm. If that changed, please let me know. That's something I was confused about.

Now I'm thinking a faster speed might help smooth things out rather than the slow speed I have now.  Wootz used a 10" wheel on an 8" 2800 rpm polisher, so...
