Accuracy of engineers level

<< < (2/4) > >>

eskoilola:
it is just mathematics:
If the sensitivity of that machinist level is 0.3 mm per meter this means that it can tell a 0.017 degree difference in the angle which is HUGE when compared to an arc second (0.00027 degrees).

Thanks Pete I fogot about the minutes for a minute there , oure Eclips level has 0.5 second accuracy stamped on it .

So -assuming that I would check the ways with a machinist level, what would be the accuracy needed here ?
0.3 mm/m would tell 0.1 mm differences between the ways (they are about 15 cm apart). Is this accurate enough or do I need to go down to 0.01mm range in order to get any benefit of this procedure?

I think your missing a 0, I have a Moore and Wright that is 0.03m/metre, 0.3m/metre would be good for an ordinary level!

Rollies dads method.

This is a method for aligning a lathe that does not require a level.
