As I said before: "a clever idea".
I cannot recognize in the photo how the stone diameter is set. but with that adjustment your design will be very suitable and above all easy to use.
I suppose there will be a lot of potential customers

Nothing... isn't that the same thing?  ???

... then maybe a spreadsheet would be just as easy.

And what is wrong with my tables?
A clever idea and beautifully executed!
However, the tolerance is greater than the stated 0.5°.
The variation in stone diameter (150-250 mm) already gives a tolerance of 1.27°. See attachments.
Other adjustment tolerances are added to that.

... a prototype that can handle an accuracy of approx. 0.5 degrees right now.
I'm curious, show it. An accuracy of 0.5 is certainly good enough.
The black marker method can be used for re-sharpening.
The photo shows my Front Vertical Base. I got it from 'Wootz' as a thank you for my angle setting method. Apparently he used the supports of the BGM-100, mounted perpendicular to each other.
I unscrewed the horizontal base from the grinder and replaced it with Vadim's construction on which I mounted the horizontal base again, but now vertically.

so why bother ?
Whatever you use, the anglemaster (probably most users as you said), Dutchman's tables, Kenjig or sophisticated software, once you've set up the USB you can use the same setting to sharpen a wide variety of knives. by simply setting the projection distance to the original value with the adjustable stop.
But then that adjustable stop must be available.

I appreciate previous comments but there is a glaringly obvious issue here. And we Let's challenge Tormek to do the right thing and produce a self centring jig with the ability to adjust the stop. It isn't rocket science surely?
Hurrah. I fully support that!
It should also be mentioned that Hakan Persson, the current CEO, also has 10 patents and more will most likely follow.
Yes, that's a good cause for celebration.
Torgny Jansson, however, already filed a patent in 1978 for a jig that we now know as SE-76, but with its own support instead of USB. See "Fig 4"
In total, Johansson holds 13 patents according to Epacenet  See attached list.
In 1982 he applied for a patent for the device as we know it today: "Device for grinding and/or honing"
In a shop of old books I found a manual in Dutch in which the "Supergrind 2000" is presented as the latest machine. This is probably Tormek's oldest handbook on sharpening.
That is very clearly explained.
Thank you very much Rick.

Since this is a "sticky" I'll add this link here...

Knife Sharpening Calculators available

... probably every app/calculator/spreadsheet made, came from, or was inspired by Dutchman's work.   :)
Thank you. I have added the link to the first post of this topic.

How do you hide the link in the 'title'??
This topic has been made sticky so that it will always be at the top of the board. To ensure the availability of the most important documents, they are attached to the first post at the beginning of this topic.
The size of the booklet versions was outside the allowed limit of 1024Kb. However, the Adobe Reader app offers the option of printing the A5 documents as booklet on A4.
