An enginers level is usualy half a second thats 120th of a degree , put across the ways at each end of the bed to check and ajust for twist .
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!

I assume m/metre should be mm/metre?

Matthew,
I think you're missing more than the odd 0! :scratch:
I assume m/metre should be mm/metre? Yep, double typo!!

This is a 2 kilogram piece of iron. The scraping is still visible on the bottom surface so maybe this has not been used too much. If someone has an estimation what is the age of this thing - this bit of information would be greatly appreciated. Someone said that these things could be calibrated. In this case that would probably mean breaking the seals on either end. I already tried whether I could get the same reading by turning the thing 180 degrees. The only surface that is stable enough here in my germany apartment is the ceramic stove. By using the chopping board as a rest I could determine that this thing is not too far from being calibrated. When the device was on the table I could center it by choosing a suitable place to stand. This apartment has wooden floors.... | (http://kirppuja.fi/Public/madmodder/IMG_5027_small.jpg) (http://kirppuja.fi/Public/madmodder/IMG_5027.jpg) |
