HOW TO CALCULATE REBAR BEND DEDUCTIONS

There is a formula you can use to calculate the bend deductions needed when bending rebar. Watch this video to find out how to do it yourself with any bar size and bend pin size and angle.

thank you for the great video!!!

I have been using X = (Roller Radius + Bar Diameter) - Required Leg Length. Seems to work also

[@TheMichiganFishHunter]

We use the same

[@dinosexisted956]

As a table bender/automatic bender in faster pace environment, I use left over scraps and "waste" a bar figuring out the right angle

[@dinosexisted956]

Ain't nobody in our shop got time for that

[@kam69247]

Aye me to man me to

[@brandonsmedstad3033]

Same but usually only for radius or more complex bending like galloping trusts. All other shapes are pretty much memorized and easily done the first time if checked properly while manually setting up.

[@ThyialIndustries]

Any chance you know how to drive that formula? Or can point me in the right direction?

[@brandonsmedstad3033]

I got taught a bit different but works the same. Diameter plus pot size would be take off for 90° then measure from front of pot instead of center.

Thanks Steve!

hello sir, do you know what is the minimum size of a rebar bending pin need to bend a 22mm rebar? ive been try to find a table but i cant find one.

[@toddfalk]

CRSI specs 4" center mandrel

[@ronnelcomia9849]

What is the size of bend pin?

[@brandonsmedstad3033]

4 in pot is standard for #6 bar

[@brycemorrell2961]

All you need to do is the bar width behind the pin then out to your desired leg length for a forward bend no math required

[@oscaro3739]

I was gonna write this to that’s how I learn

[@TheMichiganFishHunter]

I use a different formula, would only minus 3, bend on 9, and get the same result faster.
