Thanks for the responses! I have a cheapo Craftsman digital level with 0.1 degree resolution and a not so cheap Leica Disto D8 that measures angles with 0.05 degree resolution. I checked the specs on a Starrett precision level and found that the graduations in the vial are separated by roughly 0.025 degrees. The spec is actually 80-90 seconds. Then, I thought - suppose I took my plumb bob and hung it from something oh about 5' high and attached to a parallel that sits across the ways. Unless I botched my quick calculations, a 1/64" movement of the plumb bob would represent about 0.015 degrees. Time to do a little testing! This is on the back burner right now, but I'll report back with results on my zero cost precision level when the project moves forward.
