Knife jig à la T2

Wolfy, you may be correct, I have not tested all possible arrangements. It also depends on the desired bevel angle. It is easier to get the necessary handle clearance for 15° than for 20° bevel angle.  ;)

I have chosen the horizontal position because it provided larger handle clearance for quite compact solution i.e. the USB was not too far from the stone.  :)

I was thinking of vertical with a block of 30mm width and 50mm deep, profiled according to the wheel/ knife sharpening angle etc... that will move the USB out.
I do consider to try to cut a SVD-110 to 30mm and produce it that way.

I'm curious about your solution, it can work well but it needs to solve a few details. Your idea to profile the spacer block according to the wheel is correct.

Consider how you will set the bevel angle also. Using the Anglemaster I set the angle of the bracket base (shown in red in the attached picture). For a 15° bevel angle I set the angle setter at 75° for the bracket base because 15° = 90° - 75°.  ;)

If you direct the red line towards the stone axis you will theoretically sharpen an infinitely sharp edge with a 0° bevel angle!  8)

Good luck and keep us posted!  :)

I looked at it again and came with same conclusion as I had 1/2 year ago.
For practical usage a pivot point should be established at...........
Same as on the T2. A jig that is needed could be made of round profile bent and used as USB in it's original base on the machine. I can also think of other ideas to bring the pivot point to the right place. Tormek has the resources to built it if they would like to invest in this. I left the idea long ago.
For me the T2 is not a good alternative yet, as the magnet problem is not solved. Placing a magnet near the knife resulting in magnetised knife with lots of metal dust on it, is wrong in a food environment.
