Master Bender is a program for aiding you in bending conduit raceways. It takes the math out of bending and allows you to concentrate on the task at hand. Master Bender uses a more precise conduit bending algorithm than commonly used in the industry. Most people use the cosecant method that has been around for years. However, using the cosecant method for conduit angles larger than 30 degrees and conduit sizes between 1ผ and 6 inches will cause large errors.

Master Bender's algorithms automatically compensate for shrink for any angle, and Master Bender takes the characteristics of the bender into account. The results are far more precise than is possible using the cosecant method.

Bending conduit using Master Bender is easy: Select the bender tool and the type of bend, enter the angle, the distance to the object and the object height, and Master Bender instantly gives you the results in feet, inches and fractions of inches to the nearest 1/16th of an inch.

Master Bender 2.3 includes:

  • Supports over 80 hand, mechanical, electric (sidewinder), and hydraulic benders plus custom benders.
  • Shrink and gain automatically corrected.
  • 90 degree bends and back to back bends.
  • Offset bends, Three Point Saddle bends, Four Point Saddle bends, Compound 90 degree bends, Segment bends, Concentric bends, and Parallel bends.
  • Gain & Take-up computations.

Besides aiding you in bending of conduit raceways, Master Bender also helps you perform other common tasks for electricians:

  • NEW Scientific calculator with trig, power, logarithms, constants, conversions, and more.
  • DC and AC calculations of Ohm's Law.
  • Power formulas for computing horsepower, kilowatts, and volt-amps.
  • NEW Unit conversions of more than 250 units in 19 categories.
  • NEW Series and parallel circuits computations of resistance, capacitance, inductance, and impedance.
  • NEW Reactance computation -- both capacitive and inductive.
  • NEW Locked rotor current.
  • NEW Master Bender includes a Windows desktop/laptop version in addition to the handheld version.
  • ENHANCED Tables of the sizes of the common conduits, drills and taps, and (NEW) lug torque.
  • "Cheat-sheet" for bending using the cosecant method.

Note: Master Bender is not an Arkansoft product. We just distribute it. If you have questions regarding installing and using Master Bender, contact info (at) paweng.com

TESTIMONIALS

Just got my new Palm Centro smartphone for 49.95$ and it does everything for an electrician.

The time is synced, it shows seconds, and is accurate to less than 2 seconds to GMT. Also I can do Google Maps that find my location like GPS.

Best of all the electricians software is engineering grade and can do most common calculations in seconds with software that costs a fraction compared to other programs that cost 300-500$ or more.

One can design, build, double check in-the-field complete raceway systems such as conduits, wireways, aux. gutters, cable trays, conduit bodies, pull boxes, std. boxes and more.

The big 5 calculators are included Voltage drop, Ampacity, EGC/GEC, Conduit Fill and Motor Data.

Also there is an Ugly's style pocket reference, a trig, simple and fractional calculator included.

I would highly recommend this product to any type of electrician industrial, commercial and/or residential.

— L.H.- Hayward ,CA

"With Arkansoft's recent IBEW special, I was able to get both the software and my Palm Z22 handheld PDA for less than $100!
I like that the calculator is easy to use and how I can go between LectriCalc and Master Bender with ease. There's a fractional, simple and trig calculator built in, plus much reference material. The module I use a lot is conduit fill, and it has over 60 wire types for various raceways!
The software is Internet-upgradable so I've received a lot of free updates and I use the handheld computer daily in the field. I would recommend this product to all electricians and those who are getting into the trade."

— R. E. Rogalski -Campbell, CA

Wireless Customers* can run LectriCalc
on Smart Phones like the $49.99 Palm Centro!
