I bought this before I started woodworking to do carpentry like circular sawing the full length of a piece of plywood. So when I bought a jointer, I wanted to use it to check for coplanar. But of course the precision of this inexpensive straightedge found at a big box store was very questionable.
But using the technique found at http://lumberjocks.com/topics/16233
I checked it out. In particular, I scribed a line using a knife blade, flipped it, and scribed a second line hoping to match the first. And it was right on!
For the purposes of setting up the jointer, I was using only one of the two 50” pieces. But I used both pieces to do a second check. I put the two pieces face to face and checked for any gap between them using feeler gauges. The biggest gap was 0.0015”!
Maybe I just got lucky in this particular unit because it is not marketed as a precision strightedge. Nothing of the sort is presnted in the packaging or specifications.
Such a deal at $20. And I’ve got two 50” precision straight edges. Hard to believe, isn’t it.
