Ruler Washer Strikes Again!

David Charters (Durham NC)

>I was cleaning up a #4 1/2 yesterday, and came across something interesting. one of the washers, for the screws that hold down the frog, had markings on it like it had been stamped out of a piece of a ruler. With part of a number, and markings. I had seen this once before on a #3 and I think I mentioned it here. The #3 was a sweetheart era one with "Made in USA" embossed lengthwise beside the tote, and the orange frog. This #4 1/2 is a type 11. I'll try to post a picture of the washer I came across yeaterday. Anyone see this before?

>If this plane was made during a war, it could reflect some metal shortage. It also could reflect a ruler that didn't sell, so they recycled.

>If that's a 1/4" hole, it's probably metric which may explain slow sales and recycling. Notice it's marked in 10'ths (mm) and the numbers are cm.

Not neccesarily metric.

>Could be, but the back scales of framing squares are marked in tenth's and twelfth's.

It was the tenth scales that allowed the old math tricks of figuring your weekly pay and such w/your framing square, basically just a rise/run ratio calculator. Or, a pay rate/pay period ratio calculator.

The twelfth scale let you work in 1"=1' scale easily.

>it's a frog screw washer, the largest of which I'm familiar with are 1/2 to 9/16" OD max. That's 1.27 to 1.3 CM, just what the scale indicates.
