Inspired by an antique trammel set found at a woodworking show, the Veritas version is made of stainless steel for durability and corrosion resistance. The removable points score clear lines on any wood and are also effective on aluminium, brass, bronze and mild steel. Knurled sections make the tips easier to remove. With the points removed, the trammel bodies double as square gauges, clamping onto a square to make repetitive angle marking easy. The trammels will fit onto any rule or straight edge up to 6.35mm(1/4") thick. Being narrow bodied they can scribe a circle with as small a radius as 14.5mm(9/16"). Each trammel is 12.7mm(1/2") and 63.5mm(2.1/2") long overall. Made in Canada.
