well to day i was out and about when i stoped in and old pawn shop that was way out of town. I was looking for a calaper for my foldars, i ask the man and he puled out a box if micrometers and said there you go. most where junk but i found a starrett No.3 micrometer which seames to have been made in the 1910-1917 era. it works great and has no rust. the onley thing is that it is off by 1.5 thousandths, meaning that when i close it all the way it reads 23.5 thousanths. so realy it goes past the 0 and stops at 23.5, how can i calabrate it. i looked all over the net and could not find anything at all. this tool has the little rachet nob that clicks at a cirtin tork and on the end of it there is a small flat head screw. what can i do or am i stuck being 1.5 thousants off? o ya and i got it for 6 bucks total with tax, cant beat that
 
It takes a tool to turn the fixed scale so it lines up at zero on the thimble (moveable scale).
the tool is called a c-spanner wrench.
PM me your address, and I'll send you one.
 
O so the fixed shaft that is atached to the c clamp looking that has the scale will turn. i noticed that there is a small hole on the back side of the scale. thanks ill send you my address by email. is this a good micrometer?
 
Just keep looking. You can find a more recent vintage Starrett, Brown and Sharp or Mitutoyo .0001 reading mic in good shape for $20.00 if you watch ebay.

J is right, I bought a new Fowler for $7.50 and a dial caliper (new) for$12.00 on ebay last winter. It looked like there were more listings than I wanted to look at. The best part is, they were sent right to my door.
 
Jarod, I'll send you the tool. Maybe a couple different ones to make sure it's the right one...
No such thing as too many tools.
 
thanks so much. how come you can never have enought tools, i never seem to have all i want and i allwase want more. this has to be one of nutons laws i think. so this micrometer is not a good one? and i should find another one? it seames to be built like a rock and runs very smoth
 
I have a few older Starrett tools and to me they are just as good as a new one. I would adjust the zero point and use it. Probably hand it down to your grandkids.
