Is there anyone who has the multiplier table for bending conduit? I would like to print out and laminate a copy of it in a pocket size format so I can start carrying it with me every day.

Thanks

I had metal number stamps I stamped in the flat top part of my 1/2" bender.

5 5/8 deg = 10.207
11 1/4 deg = 5.126
15 deg = 3.864
22 1/2 deg = 2.613
30 deg = 2
37 1/2 deg = 1.643
45 deg = 1.414
60 deg = 1.555

I round to the 1st decimal place and I know the common ones but I wanted to check myself so I listed all from one chart.

There's a good article at www.electrician.com in Articles 1.
I would have done the link right to it but wanted you to check out the rest of the stuff.
Otherwise, just use the cosecant of the angle you want to bend.

E-mail me your address and I will send you some of the pocket-sized tables we use at work.

Ralpha494,
Your link is from Gerald Newton's site. Did you know that he started his form up again after a bout with being SPAMed?
Mater of fact the very latest post of his was about conduit bending. I'm not a conduit guru that has the experience to answer his question but maybe one of you guys can.
The subject is:
"Opinion about the Benfield Conduit Bending Manual by Jack Benfield - Gerald Newton 23/PST Tuesday/January/24/06 (0)"
It's another good place to hang out. http://electrician2.com/elwwwboard/wwwboard.html

The multiplier is the cosecant of the angle. A lot of calculators don't have that function, but it is also equal to the inverse of the sine of the angle.

The multiplier method, even if not perfect, is fine for small conduit or stuff thats hidden. You can usually get it close enough to make it work.
If you have to be acurate, the best way to bend offsets is to field bend it. Field bending is described in a some books. I have an Uglys book and it is described under "Chicago Type Bender Off-Sets" This method can be used for foot benders and hydraulic ones.

Here is some info for Greenlee and Ideal Benders. Maybe you will be able to cut and paste and make up some pocket cards.

Hope these help.
