Trammel Head Beam Compass Set, 57" Diameter Range, Hardened Points And Pencil

Nothing beats a beam compass (or trammel) for measuring, marking or scribing large arcs and circles outside the range of those possible using a standard size compass. This set comes with 2 movable heads that lock down tight via knurled knobs on 3/8” diameter chrome plated beams. The beams have flats along the top to prevent rotation of the movable heads once they are locked down. The set comes with two 14-1/2-inch beams and a connector to link both beams together for a longer reach. Using just one beam allows scribing or drawing arcs up to 14-3/8 inch or 28-3/4-inch diameter. When both beams are hooked together one can scribe or draw a 28-3/4” radius or 57-1/2-inch diameter circle. One head has a fine adjustment with 1-3/4 inches of travel. Fine adjustments are made via a knurled wheel. Each head accepts either straight or bent hardened tips, and the kits comes with 2 each straight and two bent tips. A pencil holder is included that accepts a .300-inch diameter pencil and locks on the end of a beam with a hex screw California Residents: This tool may contain a component part or create wood dust which contains a toxin on California's Prop 65 chemical list.
