Deck Leveling Gauge

[Mad Mackie]

Most of the mowers that I service have blade height settings at 1/4" increments, I don't use calibrated styrofoam cups.
I do precision drilling/milling on my vertical mill to .001", my drill presses are used for non precision stuff.

Yep, I've done the milling, drilling precision lathe work thing and in my younger days when my eyes were better I worked as a jeweler and could spot a ring mounting off 0.001. But possibly someone is interested in adopting the easier method I posted rather than knocking it down before trying it. I didn't expect those that have it all nowed up to change their ways much less give credit.
