I just noticed the 24 did not appear to have the double lines flanking CRAFTSMAN, which would place it after 1972 or 1973 when the model numbers first appeared, but before 1976 or 1977 when the double lines were re-introduced. The “mm” stamping was not used until even later. I wish someone who...

Based in the variations in the width of the raised panels on the back of the wrenches due to deep stamping on half of the wrenches, if I had to guess, I would guess early ‘80s. I stand to be corrected. Nice set! If I had beaten you to them I would have bought them! I’ve been buying “MM”...

A photo of the front of the wrenches would be helpful. Are there double lines either side of CRAFTSMAN? I suspect that there are, which would date the wrenches to no earlier than 1976 or 1977. The outlier is the 24mm wrench with the lower case “m”s. On the assumption that the wrenches were...

Sounds like you have a good one. Believe me they don’t all run 0.001” TIR. It also depends on how you measure the runout. At Jacobs, a 1/2” chuck, for instance, would be measured at half capacity (0.25” dia.) and max capacity (0.50” dia. ) about 1.5” out from the jaws. A typical spec would...

At least through the early ‘80s Jacobs was the American importer for Albrecht. I remember well that old man Albrecht could not meet the American demand for their fine product and repeatedly refused to put on a second shift. Jacobs was forced to go to Spain for the knock-offs.

Hello all. Long time lurker, first time poster. Jacobs chuck history is a personal fascination. I worked at Jacobs Clemson from 1969 until 1985. I got out just before Chicago Pneumatic was taken over by the Rales Brothers, spun off 4 years later as Danaher. I was a toolmaker. My best friend...
