I used to work as a steel brake press/shaer operator - cant say I enjoyed it...
Oh and the tolerance was 1/16 where I worked...
Try coping with a Cincinnati from 1915.......
The ram has a problem with level.
I've machined metal to plus or minus 10 millionths of an inch and glass to about 10 billionths when I made the optics for a 12.5" telescope
How is that possible?
Well I suppose it depends on what gauge metal you're using.
I wouldn't even know how to measure such a measurement...
Farthest I think I could handle is 1/64th... beyond that I think it would tak take days to a) cut the piece and b) bend or form it....
I remodel my house.
Everytime I get a room done I start thinking how I could have done it better. Its a cycle.
Do you expand, as well? Or just keep working on the same rooms?
I sometimes wonder if it's possible to take a roof off and add a second story. Just generally speaking, from a construction POV.
Yea I am real guilty of expansion. The house is huge now and the wife swears I am a dead man if I make it any bigger. My next project, once I heal up, is the master bath. I want one of those whirlpool tubs.

You know I was wondering the same thing. I have a Bridgport mill and can get down to one 10,000th of an inch with a little bit of work. I can get down to one 100,000th of an inch with a TREMENDOUS amount of work. There is no gauge or instrument I have ever seen that can measure even one millionth of an inch. That is electron microscope territory.
A BILLIONTH of an inch is off the hook.
