electrical conduit bending
electrical conduit bending
(OP)
I have been an electrician for about 10 years and just reasently I have been put in a higher position in my company. So this means that it is my responsability to teach younger electricians the trade. The problem that I am running into is that I do not have any set paperwork on how the proper way to bending EMT. If any one has that paperwork it would be a great help

Visit the National Joint Apprenticeship and Training webpage at njatc.org then click on njatc bookstore. They have an instructor's guide on pipe bending that may be helpful. Also, "Ugly's Pipebending Handbook" is a pocket sized resource you could purchase for your students.

Available through their website.
Also, in the back of the UGLY'S ELECTRICAL REFERENCES (available from Maintenance Troubleshooting, 273 Polly Drummond Rd. , Newark, Delaware 19711 (PHONE 302-738-0532)...is a nice section pertaining to conduit bending.
UGLY'S is a book that EVERY ELECTRICIAN should have.
You can get a free faxed catalog from the supplier (800-886-0532).

1 1/4 inch EMT is actually about as easy to bend as 1 inch...because you'll use a "Jack" bender (invented by Jack Benield, this bender has a 'jack' that is used or extra leverage. And you're right...practice makes a nice scrap pile. Lord knows, when I came up through the trade I sent almost as much to the scrap pile as was hung in the ceiling.
I had an estimator who figured extra conduit if he knew I was going to be bending it. (Maybe that's why they set me up to foreman so quickly - lol).
THE VERY BEST BET, though, is to use a hydraulic bender and TWO torpedo levels. For intricate bending, put a connector on one end of the pipe and place a box there...so you can keep your conduit plumb. If you're using GRC, then thread one end and attach an LB condulet. Placing one level on a flat surface of the LB will give you the same effect. You WANT to keep it plumb. Use a protractor to determine the angles. NEVER trust the angle finder on ANY bender...they'll just cause you to send more pipe to the 'pile.'

Simply refuse to bend anything over 1" with a hand bender. If your boss does'nt like this...Too Bad!!
