Stopped by one junk sale (I loves me my junk sales).
For the grand price of $2, I came home with
a Proto 4" adjustable (7045L) CLICK-STOP,
a CRAFTSMAN (underline) BE 1/4-drive flex-head handle c. 1935,
a Crescent All Steel screwdriver/hammer, a large one:  6" blade; 9 3/4" overall (This one is Pat Pending, which puts it between 1914 and 1917)  It has a crescent moon logo with a C inside, and an o inside that.
a single--dang it--Stanley No. 4 trammel point.
Life is good in the North Woods!

FOR 2 BUCKS!!!!! You didn't buy em you stole em.
A great start to the day.

Did you get the trammel point with the pencil holder?  If so, life's not over, as you probably know: a nail through the stick gives you the fixed (pivot) point, and the trammel point is your adjustable point.

No, Bill, I got the steel point.  But I figure a pencil and some duct tape will do the trick!

Or you could drill the hole for the pencil in your stick, then use the trammel point as the pivot point.

But, yes, duct tape solves many problems, although cleaning off the adhesive residue is a hassle.
