It is/was a small "square" made out of aluminum, but had an added surface at right angles to the main arm of the "square". I was told it was used to check the hammers being square to the shanks in the hammer hanging process.  I use that tool as described, as a quick check. It can be used to see if there is any Vertical Pitch, as well. </DIV> <DIV>Your approach using the block of wood and the Compass is really slick.

Very clear. I guess I'm concerned about the fact that the shank is tapered and weather I should use the top or center of the shank when measuring. I guess I'm splitting hairs here and you have way more than 1º movement between the shank and hole in the hammer when you're glueing up. Oh well, I've been called anal before. <DIV><BR> <DIV><SPAN style="WIDOWS: 2; TEXT-TRANSFORM: none; TEXT-INDENT: 0px; BORDER-COLLAPSE: separate; FONT: medium Helvetica; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px" class=Apple-style-span> <DIV>Al -</DIV> <DIV>High Point, NC</DIV> <DIV><BR></DIV></SPAN><BR class=Apple-interchange-newline></DIV> <DIV>PS, Considering your vast knowledge base (I'm not joking here), you should work on your photo capabilities. :-), (joke).
