SVM-00

[Pietje]

Hello forum!
Sorry, sorry, sorry for my bad English. That is not really my tounge.
The Tormek jigs for knifesharpening cannot center properly to flip to 180° around.
My SVM-45 flips correct for knifes with 2,1mm thickness of the blade.
My SVM-140 works well with 3mm.
The mount of the SVM-00 is 3mm thick. WHY??
Tormek says, the SVM-00 is to use only with the SVM-45.
Little pocketknifes will be holden also by a 2mm mount. And with a little tapeline everyone cann adjust the centering to his jig.
Now I have to go to a shop to grind 0,5mm per side to have a propper flip.
Or is there a real reason for 3mm?

Have a nice day
Pietje

Hello Pietje,
and welcome to the forum.
These are interesting thoughts.

However, the mounting bar on my SVM-00 is 2.50mm, not 3mm.

These 2.5mm would be

a) close (enough?) to the proper value for the SVM-45
b) quite sturdy and
c) probably stock material

This is just pure speculation. Don't have your SVM-00 ground down too far.

Look at the Tormek photos of the SVM-00. Tormek states it is designed for small knives. I believe it would be more accurate to say it is designed for small carving knives with substantial wooden handles. In my opinion, the technique that Wolfgang Hess demonstrates at 50:00 in this video is more practical for small knives:

I am puzzled by the 3mm of the SVM-140 which is supposedly designed for knives which are both long and thin. I think of a boning knife as thin (flexible). Have you ever seen a 3mm thick boning knife?

Pietje, Tormek produces these online classes in four languages, including German.

Thanks for your answer, Mike.
So there is no real reason by the professionals in this forum.
My aim is 2mm or 2.1mm thickness, so my SVM-45 can flip proper for 180°.
I am sure, this is strong enought for all grindig forces. But yes, my Excel can calculate this for control. You gave me a good hind.

Thanks for sending this link, but in my optinion shims are not good for the handling.
I will use them only as an exception.
At last also the guy in the video modified the SVM-45 by  shaping 0,5mm and 1,0mm away from the groundplate.
This is a systemtic mismatch. To grind the mounting bar to 2mm takes one problem away from me.

No, I am not a woodcraftman. Kitchen knifes are my point of intrest.
Thanks for the tip with the videos.

Part of that thread also talks about the thickness of the SVM-00.  There are a couple of other posts that address this...

... I think your measurement of the SVM-00 might be off? (or else Tormek makes them different now).
