Rational Sphidron Ruler
Make it simple!
Make the irrational rational!
All Rational Shidron Rulers are made of two similar spiral arms.

The irrational distances, like sqrt2 or Pi can be transformed to rational ones as requested.
All you need to perform this magic is a Golden Logarithmic Sphidron Ruler for this operation.
As by Fibonacci numbers - by increasing the numbers of subsections - you can finely approach the Golden Mean, you can divide any sequence of the spiral to as many parts as you like to approach it. If you have a Golden Logarithmic spiral, you can slide any sequence of this spiral to any "point" of it from which you can approach the A and/or B as precisely as you like by smaller and smaller golden sequences.
With the Rational Sphidron Ruler you can make any distance rational.
Special thanx to Kathy Pedro, Lisboa
