Toot

Written by gigabecquerel on 2025-01-03 at 23:03

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.

@gigabecquerel I keep seeing these giant granite blocks for metrology at auctions, and I have no need for one, and yet... And yet...

@wcbdata Granite surface plates are such a joy.

If you're at all fascinated by "things feeling nice" go get one! The small ones aren't too expensive, and once it's part of your toolset you will find uses for it everywhere.

@gigabecquerel What would be the parallax error in this case? (I'm not familiar)

@rubinjoni The reading of the dial gauge is cosine(angle)*actual reading. If the gauge is perfectly perpendicular the cosine is 1, but if it's not you're reading lower than the actual value.
