generally its the die thats the weak point on the model 3s and they use the same dies, correct? if so then I would say its doable but at its limit...stuff that thick its usually better to use a HF poo bender

I've had no problems with dies in my JD2M3. A couple weeks ago I bent some 1.75"X.250" wall DOM and bent the sh1t out of the follower bar pin. I'd rather bend that than the follower bar itself. BTW, it took myself and a buddy to bend four 90* bends with a 6' cheater.
From what I remember about the JD2M4 bender, the basic structure and dynamics are the same but the arms and supports are taller to accept larger diameter materials. If it uses the same size pins as a JD2M3 your gonna need more replacement pins. Oil or grease the material, make it as easy as you can on the bender

The dies are different for the JD2-model3 & JD2-model4. They are "priced about the same", but there is not a weldeded on tab on the model 4 dies, like the model 3 ones.

Manual bend or full hydro?

I'd just go for it!

Only time I had a problem... didn't space the base plate off the stand. Opps. Added some washers for the center pin to drop down correctly, viola no more problem. Stand is built from "what ever scrap was there, and hit with what ever paint was left over" I-beam and gray would have been my preference, but I'm cheap. Oh, hydro bender... so the stand just holds it up, but keeps out of the way for a upside down "U" bend.

I have bent 1.5" .250 wall DOM in a Model 4 with no problem.

I think Scott at Rockstomper has bent 2" .250 wall on his hydro'd model 3, so I'd ask him to be certain.
