When I got back from the dentist at around 1:00 pm I started bending up a little rail job for a friend. It came out great, the bender seems strong it does chatter a bit on stainless steel, so I put some Beeswax on the pipe before it goes through the follow-bar, and it stops the chatter. I have used so many benders and have so many habits from them that it took me a few bends to feel at home with it. But all and all it works well. The only other bender I have used that will do this tubing is the Hossfeld extra heavy-duty bender with the hydraulic system. And I am sure there are some high-end benders that will also do it but for under two thousand, those are the choices.
These are the wheels and Step-Locks that I plan to put onto a rolling table for the bender.

Reply:If you are going to weld stainless steel tubing, you have to preload the pipe that is getting another pipe welded to it. Or it will bend a lot from the weld. I use a little gizmo I made that uses one C-clamp to preload the pipe. After it cools you just take it off and it is perfect.

Reply:Nice. I put hydraulic on my mod 32 a couple months ago. I have only bent one test piece. Have used it manually on a couple of jobs. I think the the mod3 is a better manual bender than the mod32.
Reply:Those are nice bends. What is the machine with the huge pulley?

Reply:I have always wanted a bender,, is any of these benders capable of bending 1" diameter solid steel round bar? Everyone talks about tube and pipe,, but, it is hard to find anything about solid round.

Reply:I like your design. Never considered offsetting the clamp.

Reply:Funny. I have straightened tons of fencing and railing. With setups in that configuration. Yet when making a tool to preload tubing, I made it with the clamp in the middle. Symmetry?
Reply:If the fulcrum is centered, and the end points equidistant from the center, I don't think it matters where the clamp is. It works applying force to both sides of the pipe on either side of the weld if everything is in equilibrium.
Reply:if the clamp, and the other welded end piece, are the same distance from the center, you're really just forcing the pipe to rotate around the fixture itself. The fixture is the plane..........and the pipe is the material trying to conform to that plane.
Reply:In other words
The damn center thingy is pushing against the weld area
Reply:Don't mind me. I just finished an entire tray of fig newtons, and I got one heckuva sugar high
You eat one, and you can't stop
Reply:his setup is easier to handle and fabricate. You can also get more leverage by moving the clamp. I am pretty sure i followed a design by Brainfarth. He made a nice one. So it is his fault, I built mine with a center clamp.

Reply:This is the one I made for the 3/4", 7/8", 1", and 1 1/4" solid bar. I took the right-angle grinder and broke the sharp corner so it would not dig into the stainless pipe and used it, haha. I will make another one just for 1.66" O.D. Pipe.

Reply:The JD Square is one of the nicest around for bending tubes. Race car guys love them. Me, I have a Hossfeld with hydraulics, its rough and crude and will bend tube, pipe, square and retangluar tubes, angle iron and flat bar. dies get expensive...It seemed like a good idea at the time!

Reply:I got my little bending cart made for the JD Squared bender. It came out nice. Very solid, and stable, with or without the step locks engaged.

But if you get a Press brake/break, or even a press and a V-block and ram you start not using the Hossfeld as much. I used it to bend an arc into iron handrails and aluminum and brass handrails with plate aluminum-supported Teflon die's I made for it. I miss it. Sincerely, William McCormick

Reply:This is what I did with my JD2 model 32 bender--mounted on a custom made frame I built to fit an ancient Kennedy roller cabinet. Installed the electro/hydraulic power pack inside the cabinet, with the motor end just barely poking through for cooling. Bending dies are stored in a rack at the bottom; accessories and related tools in the drawers. Wired it through the cabinet for convenience. Also shown is my first bending project done with it.

Reply:Made a back- breaker tool. I only cut the hole, everything else was precut drop. Used on this 107 feet of pipe rail. Worked well. I rarely get pipe jobs, this was kinda fun.
