Just wondering what is the general consensus of when you consider something is level enough...
I have been levelling my lathe with my newly acquired Starrett 199.. I have tried to get it near perfect within the sensitivity of the level but can only seem to manage to get it all within 1/2 a graduation so it is about 0.00025/12" which I assume is plenty good enough... One issue with the lathe is it has a centre support in the bed that does not touch the ground but is part of the cast base. If that support is not perfectly in line with either end supports it means the bed cannot be straight. but raised or lower in the middle..
But what sort of accuracy is the general consensus on what is a good standard on getting guide ways straight...
