The die doesn't need the grease. The support block does because the tube slides through it while bending. the grease on the die was to keep it from rusting. but I did put a little on the groove when bending. maybe that was wrong

Can't be too wrong. You built a whole car that way. Besides, the die doesn't do any pulling. The forward clamp pulls the tube around. The die is just there to maintain shape.

With the amount of force I found that it takes to pull C/M, I don't know if I would want to use something as thin as WD-40. And I did find that a little goes a long way.

I just used cheap wheel bearing grease with a brush that's what I used, that is whats on the die, just been setting up for a while. I hope you mean lube just the pins, instructions on my JD 32 said to never use lubricants on the forming dies groove, the tube will tend to slip backwards if used. don't know nothing about the JD 32, I watched a friend who has bending tube for a long time he used grease on the die. mine never slipped. Who knows, but I'll follow my instructions., besides, grease attracts dirt and grit which will scratch the tube and die then stress risers form, then all the extra work getting that mess off of everything, affecting the weld, no thanks, I'll do without it.

No grease here. I do wipe the tube down to remove any dirt, grit, etc. And I pay attention to the dies and polish them as needed. Dirt, metal grit will scratch and damage the die and the tube.
If the results don't match the theory, change the theory.
