This post got me thinking about my taps and dies. I was curious to see how many S W Card taps I had and what other makers. Of course, this isn't a scientific survey, just what I've picked up over the last 25 years. There are more different makers than I was expecting, and Card seems to be one of the most common.
I've come by most of these from buying a box of tooling or an old guy just happy to see someone have an interest in them and gives me more tooling when I've bought a machine tool. An example would be I bought an old Kennedy toolbox and paid a little more for all the contents.
None of these have been in a case. They were all loose taps. You can also see a progression in the logos over the years in some brands, SW Card being a good example. I'm guessing early taps have S. W. Card within a box and later taps just say "CARD".
I'm showing just 1/4" and 1/2" taps. Some are broken, good for grinding into bottoming taps, some are rusty and worn, I just hang on to them all. If anyone does need a size to fill out a set, let me know.
The 1/4" taps have 20, 24, 26, 28, 30, and 32 tpi.
There were maybe a dozen of each size with no mark or were too hard to read.
The makers are:
John Bath, Butterfield, UB, Bay State, J M Carpenter, S. W. Card, Morse, Wells,
GTD Greenfield, Wiley & Russel, P&W, R&T co., Vermont, Ace, HY-PRO, Sossner, E.F. Reece co., R&P, Threadwell, Bendix Besly, R&N, and Hanson.
The 1/2" taps have 12, 13, 14, and 20 tpi.
The makers are:
John Bath, Butterfield, UB, Bay State, J M Carpenter, S. W. Card, Morse, Wells, and GTD Greenfield.
I know, someone's going to say I should have the taps separated so they aren't clanking around on each other. I'm just too lazy to separate each one.
