   I scored an older unit complete with all the rods ...but they are not set correctly . The 1.5-2.5" is off by about .009" short of 1.5 when the thimble is zeroed . Looking into the end that goes into the head I see a setscrew . I think this is used to set the rod length but I want to be sure of procedure before I go reefing on it . The other question I have is about the "extended" setting . The head only has .500 of travel and there are 2 setscrew dimples in the mounting sleeves . When in the "long" dimple it's about .050" short .  I suspect there must have been a .500 sleeve that set the proper length in the long position . Any help will be appreciated !

    I guess I should have mentioned this is the Sherr-Tumico unit I posted about last week .

I wish I had something constructive to say... so instead I'll say this, "If you can make it give you useful readings it probably isn't wrong."
Yesterday I drilled and tapped a mold for bolt on hinges.  (Shop made hinges) One hinge was 1/16 inch off on all three holes.  I put a washer in between, and not only does it work great, but it looks cool like a layered knife scale.
After correction I reprinted my print and stuck it to the mill with a magnet.  Then I shipped the mold.  Now the print clearly shows a washer used as a spacer in the lower hinge.
