Metrology collection...
I was trying to find a particular dial test indicator yesterday and
got ****ed off cause I couldnt find it..so dragged everything out, layed it out and took photos of it. Its not all own..I put the camera away and found 5 more items including a mint pair of 6 & 8" Miti vernier calipers. Ill add them next weekend. Including my bench centers... Just thought Id show off the crap Ive collected over the past 10 or so years https://picasaweb.google.com/1040422...602/Metrology# Oh..anybody have a 8-9" mic..Id swap it for one of the (2) 6-7 Mity mics I have. Anyone know the proper way to calibrate the mechanical digital mics? Several of mine are off a thou or so. Handle reads properly but the mechanical digital are off a digit or two. I seldom trust the mechanical readouts..but its nice to have em match. Gunner |

Lock the thimble, then remove the front magnifier glass from the digital read. Inside you will see two screws, Loosen them enough that the number dial slides down. That will disengage the gears. Now rotate the top drive gear gently till you are at zero. Now reengage the gear and tighten the dial screws. Unlock the spindle and test. If you're at zero and zero on the body. Replace the cover and you're done. I usually strip, clean and calibrate mine yearly (or sooner if they suddenly jump as that generally means it has crud in it). -- Steve W. |
