Re: [OpenLathe] Re: Micrometers

Hello John
I have had a long time working with "mikes",since 1967 in high school.
 The last job I had before I got disabled ,was an inspector. I checked
parts that were made in a machine shop.
 That was fun to start with because they used the metric system in the
shop.It took me a few weeks to "think metric" instead of inches.
 That shop was there useing industrial  diamond tooling..
 
 Maybe what asking, or saying is that I was surprized to see that much
differerance in the standard in the "mike" box and the gage block.
 The only other thing that might be a factor is heat,but they are all stored
in the same tempature place..
 
 "Mike's"  do not work well as clamp for welding.
 
 I used to live in the High Desert, out at Barstow.

Kieth:
Did your mike come with that little funny looking "hook" of sheet steel? If so that is an adjustement tool to turn the body in the frame for final setting.  Of course, two or three tenths could be from the heat of your hands expanding the standard block you are measuring, or how tight you screw down the spindle.
 
Are you an experienced mike user?  Measuring to "tenths" takes a bit of practice to get the right feel in your hands and brain.

P.S. Remember don't use either mike to hold parts in position while welding the parts together, Neither torch nor arc are good for mikes.

Keith The issue shouldn't be the difference between the gage block and the mike standard. I should be the ability of the mike to obtain a repeatable accurate...
