Anglebeam

An anglebeam was a measuring device used to determine the angle between two objects, with a margin of at least a tenth of a degree. The Book of Practical Lightsaber Technique volume seven, written by Jedi Master Vo'ren Faalo, described training exercises for Jedi-in-training, using techniques called cadences to strike ball bearings atop wax cylinders or unlit candles. The cadences required setting the cylinders ten degrees apart and recommended that beginners use a protractor or anglebeam to verify the angle when first starting the exercises. With practice, it was expected the trainee would be able to place the cylinders to a tenth of a degree without needing to be checked by the tool.
