Achieving equilateral triangles

May 25, 2018

Below is a diagrammatic representation of Harry Boyd’s principles for achieving equilateral triangles on 6 strip rods and to help visualise the geometric shape of an irregular triangular strip.

Here is a .pdf

Essentially the method is:

You take the three measurements in sequence (1,2,3) rotating the strips in your micrometer clockwise starting with the enamel side. From this you establish which is the largest , second largest and smallest dimension.

This gives you a sequence  (eg. 1,3,2 or 3,1,2 etc.)

You then place the strip in the form and cant the plane relative to the enamel side as shown.
