Usable on any rule up to 1/4" thick, these narrow-bodied trammels can be set to reproduce radii as little as 9/16". The removable points score clear lines on any wood, and are also effective on aluminum, brass, bronze and mild steel. With the points removed, the trammel bodies double as square gauges, clamping onto a square to make repetitive angle marking easy. Inspired by an antique trammel set found at a woodworking show, our version is made of stainless steel for durability and corrosion resistance, and has knurled sections to make the tips easier to remove. Each is about 1/2" in diameter and 2 1/2" long overall.
A pencil tip, available separately, can replace either of the stainless-steel points. Additional leads, in packages of 10, are also available.
