Title: Use of KS-123 with adjustable knife jigs
Post by: Dutchman on July 19, 2026, 12:16:28 PM
The angle-setter KS-123 is not directly suitable for use with the adjustable knife jigs SVM-45 and SVM-140. However, with a relatively small correction, this is possible. In the attached report, I have described the problem and derived two possible solutions.

One of the solutions requires some calculations, so I expect again several spreadsheets to result.  ;)

From your pdf...

QuoteSVM-jigs is unfortunately not possible without further ado.
The KS-123 is clamped onto the Universal Support Bar (USB) while setting
the sharpening angle. When using the adjustable knife jigs, the adjustable
stop will rest against that clamp and is therefore at a distance Ko from the
USB.

Why are you resting the stop against the clamp and not the USB (like you do when using the KJ jig?)

Also, your reference 2 link doesn't work in the U.S.  (Need to change the nl to us)...

Thanks for your contribution
I have updated the link to the US version

Due to the curved cutting edge, the protrusion would then not match the value for the position where the knife is clamped.
