offset is a little small. The offset is the distance from (in your case) the edge of the die to the start of the bend. Usually closer to -.5

JD2 Model 4 Bender

1.5" x 4.5" die

1.5" x .120" 4130 tubing

CLR = 4.689
Calibrated CLR = 4.80563
Bend Location Offset = 1.007

7 degrees Lead In Angle
8 degrees Springback @ 90 degree bend

A couple of questions:
1) Why is CLR = dieSize * 1.042 instead of just the die size?
2) My calculated Bend Location Offset is 1.007" but if I measure from my alignment mark to where I see the die bending the tube I get 1.125". Why the 1/8" difference?

Im brand new at this but thought that the calibrated clr would always be larger than your clr. What gives with the 1.5" die? What causes it to be the only one smaller?

Just finished my new stand, now I'm ready for some "calibrated" bends. In your "guide" (rev. Nov.,'06), is there something I'm missing or can you combine steps 2 & 4? I'm doing 2 sets of dies tomorrow and don't wanna waste tube. Triple "S" (Sorry So Stupid). Thanx in advance Cris.

1 5/8" x 6" PT Die Set
CLR = 6.252"
Calibrated CLR = 7.135"

On the bend offset...Ive always just lined the mark up with the edge of the die set, and have never had any problems. Is this okay, or do I need to find where the bend actually starts when the line is at the edge of the die?

Thanks Cris!

Kyle

If you want things to be dead nuts you realy need to know where the bend starts on the die. My 6" radius die starts right at the edge so thats where I use. My 5" radius starts .375 into the die.
