I have a Veritas that came with my (used) bench grinder. and the previous owner mounted it with the base directly under the front vertical tangent of the wheel.
I saw your post and wondered if that is the right place or not. I googled Veritas an came up with many pages of photos showing the unit mounted in front of this point and behind this point. Due to the adjustable arms, I don't see it making that much difference. Could you explain why it should be moved, and to where? I'm a newbie, and old newbie, but a newbie just the same, and need all of the advice I can get.
By the way, Mike, nice build, looks much heavier than the Veritas, and I love the larger plate, looks like it would make it easier to rest more of your fingers/hand on.
I'm thinking of adding a flat top plate like yours to the top of my Veritas, then maybe I would feel more like using the thing.
