I've since coated it with 3 coats of plastic coating.
A drop of mineral oil on the platform rubbed into the now coated surface and one drop on each side of the knife to be sharpened and it's SUPER slick.
...
How to coat it, with what? Tape? Spray? Paint?

This method was initiated with the following post in 2014

It gives also tables to circumvent calculations  ;)

I think it is proper that the name of the tool reflect the rightful inventor. I will happily endorse whatever name you choose.

The name of YOUR Kenjig is not my point. However, someone asks what that tool is, and then it seems logical to me that the principle concept is explained first, before considering the realisation as a tool. ;)

By the way, how long is someone considered to be a 'newbie'. Is that e.g. related to the number of words in his  posts or on the value of his contributions?  8)

Regarding the 'basics': see https://forum.tormek.com/index.php?topic=1849.0
You could give the 'inventor' the honor for his first work on this approach  ;)

Jan, it is good for prof. Verhoeven he had retired before Gillette could read his publication.
Gillette would have destroyed him for saying loud their razors are 3 times thicker than competitor's   :-\
In the miniscule world of Angstroms and nanometers, that difference is larger than from your Czech home to Tormek headquarters in Sweden.
Can you explain this? The contempt shown here is inappropriate. Prof verhoeven has made a significant contribution to knowledge about grinding. We use that knowledge and develop it further. We must be aware that we are on the shoulders of this kind of pioneers.

Welkom Tom
On Wootz' website you can find the following info on his pricing: http://knifegrinders.com.au/02Prices.htm
Succes met het opstarten van je onderneming. ;)

This was a full-range study (unrelated to the LA-220), will be published in the US Sharpeners' Report in their December issue. I will send you a complimentary copy then.
For now can only show you the chart of BESS score as function of the Honing Angle - treat as a spoiler  :P
WOW! That is very convincing! Thanks. Are you going to post that publication here too? I would love to have a copy of it.

Thanks Vadim.
I should have added a table for 215mm, but I supposed that the 220mm was correct.  >:(

I have added an Open Document Spreadsheet (For the office package OpenOffice)
to the documents in https://onedrive.live.com/?id=4AF25953CEF4952D%21488&cid=4AF25953CEF4952D
I do not know if it will work in Excel.
You'll find there also a photo of measuring the distance to the stone. In my opinion, the accuracy of that method is good enough

Knife Sharpening / Re: Best microbevel angle
August 24, 2017, 10:35:32 AM
Is the recommended angular difference between primary and secondary bevel dependent on the angle of the primary bevel?
In his publication Experiments on Knife Sharpening (http://www.bushcraftuk.com/downloads/pdf/knifeshexps.pdf)  John Verhoeven recommends a 2β target hone angle set to around 5° to 6° larger than the ground angle of 40° (page 26-27)
So he applied a secondary grinding angle 2.5° larger, at a primary grinding angle of 20°.
It is a large difference with 'your' 0.5°, a factor 5!
Difference in the accuracy of setting or measuring the grinding angle might be the reason?  ;)

I want the honing wheel positioned such that the grinding wheel is not in the way while honing (long) cooks knives.
A separate honing system would also be an option, but would be expensive due to the additional motor.
#194
Maybe you could add a reference to "Experiments on Knife Sharpening" by John D. Verhoeven
You can find it on http://www.bushcraftuk.com/downloads/pdf/knifeshexps.pdf
I have learned a lot from that publication.

The distance is measured NOT to the top NOR the center of the support. It is part of the triangle through the knife in the jig. So it should be measured to the heart of the jig just above the center of the support. Measuring the distance to the top of the support however will give a negligible error.
Please keep in mind that this subject is not an academic item, but a proposal to simplify the jig-setting  ;) Thank you :)
