Many years ago I was in the typesetting business. One of the tools that I used was a Pica rule. I ran across this one a couple of years ago and have been using it daily since then. The hook on the end makes for extremely accurate measurements of up to 12”. They make one that is about 18”, but I haven’t been able to track one that long down. You can find them at Precision Graphic Instruments for only $9.50. Great little tool.

Been using a line gauge for 40 years. But only the past five for woodworking. As for where the “agate” came from, I’m not sure. I always referred to really small type (like the box scores on the sports page) as agate. I always measured in pica (or ems pica). And still today, it’s easier to divide something measured in pica than it is in inches. There are 12 points in a pica….. 72 points in an inch….... 6 pica in an inch….. etc. I hope I remembered that right. Good topic, Bill.

Machinists use hook rules. they come in some fairly long lengths. Try any machine shop store or catalog. Hook rules have the head riveted on so they can lose calibration if dropped. The rule shown above will not do that.

That’s really neat, and thanks to Richard for a link to an 18” pica rule. Terrific!

That is what is so neat about Lumberjocks, it doesn’t matter how much you know about something – we can always add new info to the knowledge base. What will we learn tomorrow :-). I am going to add another 18” to the arsenal, can’t see much need for one any longer than that though, but who knows?
