I used my SVH-320 planer jig for the first time yesterday and decided it was taking too long on the Tormek so I switched to the 220 grit diamond wheel on my grinder. The problem I had is that the instructions for the BGM-100 horizontal mount call for it to be mounted about 1" further away from the wheel than the vertical posts on the Tormek which won't let you center the jig on the wheel. I noticed that the BGM-100 horizontal mount on the opposite side of the Tormek is also further away from the wheel as are the mounting holes for the Wolverine jig adapter. Why the difference? If there is an advantage depending on the jig being used, why not make the BGM-100 with four holes so you can choose which one you want to use?
