Thanks for you answers. Now I played two days with it. My experiances are:

• BGM-100 is only to form the tool, which mean the figure is no perfect. For a perfect tool you must finished the grinding on a Tormek. Bench Grinder do nly a start job. Sometimes it take longer time and somtimes it is fast on the tormek
• Grinder wheel and Tormek wheel should have the same diameter (250mm), if not you get "hollow" reasen is the diffent radius as Ken said before
• So it is not the easy tool that I hoped

Hi, it is a CBN Wheel
https://www.dictum.com/de/schaerfen/schaerfmaschinen-und-zubehoer/schaerfmittel-fuer-schaerfmaschinen/704887/optigrind-cbn-schleifscheibe-oe-250-x-40-mm-superfein

It has exact 250mm as Pic10 show.

I made some more fotos, but the problem ist he same ☹

Pic10: The Tormek Wheel has exact 250mm
Pic11: 35mm is also on the top
Pic12: The bench grinder wheel has 200 mm
Pic13: The usb is mounted o Degree
Pic14: The grinder is also mounted 0Degree

The strange is that the error-angle-distance is different.
This mean if I use a tool with SVD-186 (JS=6,P=75,B) I must longer the distance from the usb the the wheel on grinder, when I use a tool (JS=0,P55,B) I must shorten the distance ☹
This mean also that the ,,error-difference" is not constant ☹

Is it ok, that the Tormek-Wheel has 250mm and the grinder has 200mm?
If yes, what could I do to solve this problem?

Hello, please help me to use the BGM-100.
After I have been using the Tormek T-8 for over one year, I bought the BGM-100 for my new  bench grinder.

Now I have big problem, that the (angle)result on the Bench Grinder is not the same as on the Tormek T-8
What could be the reason? Is it a problem that both have diffent wheel-diameter (Tormek=250 and bench grinder has 200mm on stone diameter)?
Or is my installation from the bgm-100 wrong?

And the bad results are always the same, it does not matter if I use hole ,A' or ,B'.
The same shit is by the use of SVD-186, or I change the height of the wood-block☹

Please help me to clear this situation! Thanks a lot!!

Now here are photos from the problem.

Pic1: I use the hole B on the Tormek to adjust the usb
Pic2: After I marked the bevel with permanent marker, I rotate the wheel to see the result
Pic3: Same in a bigger resolution
Pic4: The result is a parallel clear area. Which mean all is right adjusted
Pic5: Now set the TTS-100 on  my bench grinder. Also hole ,B'. Stonediameter is 200mm
Pic6: It's hard to photograpf, but the bevel has a gap, and it is not full on stone
Pic7: On the marker we can see better the bad result
Pic8: Here you can see the distance b with 35mm
