I got myself another granite plate as a christmas gift, and today I finally finished the micrometer stand for it!
It came out nice and rigid, and the knobs add just the right amount of bling 😁
Yes, I know what a parallax error is, but this kind of setup can be useful, too, just because it's more universal.
Sooner or later I'll build another adapter that then keeps the dial gauge exactly vertical to the plate.
