Bending Conduit | Offset Guide Tricks And Pipe
Typically, the electricians use conduit for wiring in buildings, and they have to turn it as to the shape of the concrete in the building. Bending conduit is not as simple as anyone can do. Conduit bending is a little tricky business. It has other uses also such as furniture frames for use in lawns and patios, and tent frames. You may find several articles as conduit bending guide to get the tricks and techniques for practice.
You need a conduit, a measuring tape, marker, and the bender to start the bending conduit. There are several sizes available in the conduits and to work with that you may get many sizes in benders as well for bending conduit. In order to get the perfect result you must use the same of bender as the size of the conduit. You can get ½-inch bender, ¾-inch bender, and one-inch bender as well. They are not very heavy and you can keep them with your tools to work with different sizes of bending conduit.
Although every bender has same style of use, but their marking is different due to the difference in size. However, if you know how to use the bender, you can easily handle any size of bender to use in your bending conduit. Every job needs proper attention and bending conduit need too. Conduit bending is a simple job. You can do it within little time with proper concentration. Follow the markings on the bender and perfect measuring can ease your conduit bending and you can finish it with accurate power to pull the handle on the bender.
You will get an arrow on every bender at the front side of the shoe of the bender to suggest the placement of bending conduit. You have to follow the star marks on the shoe of the bender as the midpoint for the calculated radius of the bend. You will get the take-up numbers on every size of bender that suggests the proper addition of measurement in the conduit for bending conduit. Normally, a take-up of five inches for ½ inch bender, six inches for the ¾ inch bender, and eight inches for the one inch bender is suggested, but you can confirm on the printed instructions of that particular bender before bending conduit or can follow the normal suggestions in case of non-printed bender.
Practically, if you want to bend the conduit on a 90-degree angle of ½-inch conduit having 12 inches long stub. Now mark on the 12 inches distance from the end and subtract five inches as the take-up measurements, the exact mark will be at seven inches to be placed exactly at the arrow mark of the bender. Put your foot on the pedal of the bender and pull back the handle steadily until you get the 90-degree angle of the bending conduit. You will get the end 12 inches high above the surface if you measure it that means you have exact 12-inched stub as you wish.
A different measurement applied for the offset bending conduit. Normally, you can add 31/2 inches in the bending mark to each inch rise in angle change of the conduit bending. You may use saddle bends to run the conduit over the other already fixed conduits. Usually, in saddle bending conduit takes two bends of the 45-degrees to run over the fixed conduits.
