jml1083 Posted December 20, 2013 Share #1 Posted December 20, 2013 I recently discovered something called a hermaphrodite caliper. We are all familiar with normal calipers, what makes the hermaphrodite caliper different is one leg has a small inward facing "foot". This foot makes scribing or drawing a line that is a set distance from the edge of a piece of wood very simple and accurate. The foot follows the edge while the other leg, which can hold either a sharp point or a pencil lead, scribes or draws a line. I found that this is so accurate that I can quickly go over the same line multiple times to make a scribe mark deeper and the scribe always is in the exact same place. The following graphic shows some of the possible uses. Starrett make two versions of this tool. The 563-6 is a 6" tool where the opposite leg is straight for its entire length. The 243-6 is also a 6" tool but the opposite leg has a bend in it about half way up. The Starrett models are a bit pricey (about $50 USD each) so you may want to shop around. The ones I own have what Starrett calls a stiff joint which means there is a nut that you can tighten if needed to increase the amount of force needed to adjust the gap and these are the ones shown above. They also have a locking joint version of both but I find the stiff joint version is just fine and the lock joint version costs twice as much. trippwj and WackoWolf 2 Quote Link to comment Share on other sites More sharing options...
