The past few years I have been working on Master Bender. It is a tool for Palm and Windows Mobile to assist electricians in the field. It is targeted at bending conduit, but contains a number of other features including a complete scientific calculator and unit converter.
When you bend conduit, you must consider that the conduit shrinks due to the detour it takes. There are rules-of-thumb for estimating how much it shrinks, but those rules break down for large diameter conduit or large bending angles
Master Bender’s algorithms automatically compensate for shrink for any angle, and it takes the characteristics of the bender into account. The results are far more precise than is possible using rules-of-thumb.
Master Bender computes accurate offset bends, three and four point saddle bends, parallel bends and more. It also contains a full scientific calculator, easy conversions between more than 250 units, Ohm’s Law computations, power computations, locked rotor currents, and more.
I developed Master Bender together with electrician Lewis Hinkle to ensure that it would be useful for work in the field.
