TRAMMEL POINTS

General's adjustable trammels accurately measure and mark distances that are too great for conventional compasses and dividers. Trammels will accurately transfer measurements, scribe arcs and lay out circles. Points can be replaced with pencils, ballpoint pens, crayons or soap- stone sticks for marking various materials.

The Precision Adjustable Trammel set is their finest, most robust trammel package. The set includes a fixed and an adjustable trammel, allowing you to dial in on your measurement with pinpoint accuracy. Also provided is a pencil holder which can be used in place of a scriber. Trammels are great for drawing large circles or for making marks over sizable distances.

Instructions:
1. Use a beam 3/8” x 3/4” or smaller of desired length. 
2. Slide fixed point of trammel onto end of beam and lock in position with clamp screw. 
3. Slide adjustable trammel on beam within 5/8” of predetermined measurement and lock in position with clamp screw. 
4. For fine adjustment, position the trammel points against a rule or tape measure. Tighten or loosen the fine adjustment screw to move the point to your specified measurement.
