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 . |

--- Quote from: eskoilola on March 21, 2018, 12:42:21 PM --- 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? --- End quote --- 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. Regards Sean |
