Hi Dave sorry I have the Phi virus and once caught it can not be shaken. But I will try to take my medicine to keep it in check.

Meanwhile I went online to try to find a diagram with measurements but was shut-out.

However how can you be so certain that they did not know Phi when it is such a simple step to get there from the 1 by 2 by sq rt of 5 right angled triangle ...



Cheers
