JD^2 bender equation

[Erik Irvine]

I was wondering if anybody had the equation that calculates the amount of length, and start point for bending tubing with a JD Squared manuel bender (I think model 2 or 3, I forget.) I know the equation came with the instruction manuel but I lost that awhile ago. The tubing I will be bending is 1.5 inch tubing with 8 (or 9?) inch diameter die. Thanks

First, that is a big die for 1.5" a 6" radius is common. As for the equations do a search for the thread called bend formulas it has everything you could ever want to calculate.

if i get your question right, you wanted to know where the bend would start at right? well, i just bought a JD2 model 3 and a 1.5" dye and in my directions it says that the bend will start 7/8 of an inch inside the dye from the outside edge. hope this helps.

Check out pirate4x4.com. There is an excellent tech article on tube bending. In fact it is called Bending 101.

6" is a HUGE radius for a 1.5 die....the most common is the 4.5" or the 5.5".

Check out the JD2 site for all the specs:

he said 8 or 9 inch DIAMETER....not radius.

6" is huge, wow most of the people I know use 6 or larger.

Good point, he did say diamater.
