KnifeGrinders Software Question...

[darita]

Hope I'm ok asking here...I'm attempting to use this software for my Supergrind 2005.  What is a good starting point for the Knife Jig stop to blade edge distance?  Any other tips on using this software would be appreciated.

Most use around 139mm for standard knives... not set in stone, but a good starting point, since it seems to fit most size knives (and I should add keeps it in the range of a decent USB height and its capability).

CB makes a good point about the generally used 139mm Projection. This is used because the short length of the threads on the shaft to allow use of the O ring.

Software questions pertain more to knife sharpening than Tormek general questions. As moderator, I am trying to keep the software questions together for easier access. I am moving this topic to knife sharpening.

The 139mm originates from my proposal on angle-adjustment in the documents you can find at the links in my signature.
You can find the following citations:

• Length between stop and clamp edge  is adjustable from 108 to 125 mm

and

Consider a cooks knife with a width of 45mm. The jig can grip the knife to a depth of 14mm. As a consequence the knife edge extends 31mm from the clamp.
Thus the distance A between the knife edge and the adjustable stop can be varied between 108+31 and 125+31 mm, that is from 139mm to 156mm.

Because the adjustment range is 17mm, all knives with a width between 28 and 45mm can thus be set to a Projection distance of 139mm.
Knives with a smaller width must therefore be set to a smaller Projection and therefore also a different USB height

Dutchman, you are quite correct. I studied your original research intensely when I was developing the kenjig, several years ago. Your work is the foundation of the kenjig. I need to reread my source material periodically; the part you mentioned must have escaped my memory. Thanks for mentioning it.
