.probably hes using that machinist level to measure, it reads in half thousands, .0005
ten thou reads like 2 decimals, in machinist language, thats not what you learned about decimals in school lol
ten thou .01
4 decimal places is .0001, we say tenths, which is kinda high precision for machinists
a human hair reads about .003 3 thousandths
I'm using a starette 98-12 machinist level. all the measurements are on the middle slate because thats all I had measured. I figured I would get the middle one level and bring the other two up to it.
forgive my ignorance. in my recollection from elementary school one tenth would be .1, one one hundredth would be .01, one one thousandth would be .001 and one ten thousands would be .0001. if those decimals aren't right please forgive me. each graduation on the level is 5 of whatever the correct decimal of an inch. I also should have said per foot I thought that would be assumed, again I'm sorry.
I would also think that all the corners should read zero but they don't, thats what I'm trying to figure out. The level has been calibrated so the only explanation I can come up with is that the center is high.
can anyone tell me what's going on or how to fix it?
I'm not questioning your math pard, but instead I think your method, or approach is wrong. Don't try and read the level qraduations, level the bubble. That's a very good level if it's calibrated right, use it for what it's good for.
any advise on how to level the bubble? I can't think of a way to raise the corners relative to the center.
