In a fix recently a small toothed dovetail saw needed setting before I could use it and I had no access to the usual nail punch (set USA) I use. I looked high and low for an alternative possibility but found nothing remotely suitable until I found a 2″ long wood screw.
Perhaps, I thought to myself, I could use this punch-like on the side of the teeth as I do normally on smaller teeth like these, but with the first couple of attempts the point glanced off the teeth without setting anything but my own teeth on edge. Then, as with many serendipitous eventualities, I pictured in my mind’s eye the edge of the screw head filed at 90° as shown below. With a 10″ flat file I filed the edge to a flat and offered it to the saw plate so that when I pinched it between my thumb and forefinger the flat edge was oriented according to the plate and the sides of the saw teeth. The threads on the screw aided the setting too in that they rested in the teeth as I tapped the edge of the screw head with the hammer to set each alternative tooth. This has proven to be the simplest saw setting device and perhaps the least expensive of all too. Once both sides of teeth are set, gentle tapping of the teeth as per my usual way, between two hammer faces, refines the setting and I was fully back to sawing action. It may not be sophisticated but it works extremely well; as good as any saw-set I’ve ever used anyway!
OK. if you’ve read the blog you’re entitled to watch a very brief video on how it works here:
