5.0 out of 5 stars Review Of The General Tools No 102 Analog Micrometer, August 20, 2008

The General Tools Number 102 (analog) Micrometer is a handy tool to have around the house if you need to make precision measurements of external dimensions up to 1 inch in size.

It is well made (the screw mechanism has a nice smooth feel) and the only exception that I have to report is that the calibration instructions (on the paper backside of the plastic cover that the micrometer comes in) are misleading as they refer to a previous (slightly different) mechanical design (I spoke with a General Tools' Engineer and this is what he told me). Instead of a 'hex tool' being needed to loosen the base ring (my term) on the micrometer (to allow the zero adjustment to be shifted) a small flat blade screwdriver is needed. In addition (the instructions say nothing about this) the screw (to loosen for the zero adjustment calibration) isn't visible until you back-off the adjusting 'thimble' (that you turn when making measurements) a couple of tenths of an inch.

Like any precision device the micrometer needs to be treated gently (i.e. don't toss it unprotected into your toolbox with screwdrivers and wrenches). If you open the package carefully (it's only secured with a couple of heavy staples) it can be reused for storing the micrometer in.

Call me old-school but I just couldn't make myself buy one of the new digital micrometers. The digital ones can supposedly measure down to .00001 inch - but are they really that accurate or are all those extra decimal places just for show? When I pick the thing up after three years lying in the tool drawer, I don't want to have to have change the battery before I can use it. This mechanical version is plenty accurate for me - measures guitar strings just fine, very precise. When I am building my own space shuttle maybe I'll consider a more expensive micrometer.

5.0 out of 5 stars Review of the General 102 after 15+ Years of Use, March 3, 2010

Original still works like new, dead-on accurate, smooth and reliable. I was kind of surprised to see it selling this inexpensively after all these years. I'd call it a bargain by any standards. Mine has the Allen head setscrew for calibration, mentioned earlier. Haven't needed to re-zero it yet!
