Which bender for roll cages, tube fenders, and bumpers?

Both are roughly the same price.
Just need to know which is better for bending tubes for things such as cages, tube fenders, side steps, bumpers, etc.

I have both the benders above, the top one will bend thick wall tubing only! bending 2" .095 wall will flatten out and kink and not look very good. the 2nd one is for flat bar only will not bend tubing.

I also have a Pro-tools MB-105HD:

with a set of 2 inch dies. bends .095 wall very well but will cost a lot more then the 2 above.

So, if $$ is limited, the top "pipe bender" will work as long as you bend heavy wall tube or pipe. and practice with whatever you buy before you build a actual part. there are many different types of pipe and tubing and they all act a little different while bending.

Spend the money in a nice bender or you will spend the money on the tube you crushed repeatedly trying to make nice bends. I have both of these benders and they bring on the suck! Get a pro tools, jd2 or similar.

I found a heavy duty jd2 in eBay for $150. The guy said he bent his JD bender(trying to use thicker tube than recommend) and therefore used his bender as a template to make a new one of 3/4-1" plate. I have one from him and bought jd2 dies and could not beat the price or satisfaction!

the first one you posted is a Pipe bender. aka a "tube kinker".

the second one you posted is actually a bar stock bender, not a tube bender. it is made for bending small round and square bar stock as well as some small flat stock as well. that style is what you want, but you need an actual tube bender to build a cage and such.

I have a Pro tools 105 HD with air/hydro conversion and love it.

I'd check out site sponsor Rogue Fab for a nice economic bender. yes it is about $800 but you won't be able to get a ready to go bender for much cheaper anywhere else.

Top one is for pipe and kinks or dimples the tubing you use. If you want it done nice get an actual tube bender it might be more expensive but you will be 200 times more happy on the out come

Fit what it's worth, the top one won't kink the pipe if you fill what you're working with with water and freeze it. The ice helps hold the pipe together. It's the same process they use to bend brass and copper to make trumpets and other instruments.

Awesome bit of trivia but how do you freeze a 12' stick of tubing? I guess some of you would be in luck but I rather have a proper bender and live in a warmer environment. I've used sand on smaller projects.

My wife would kill me if the freezer was full of DOM. Get the appropriate bender then look up the hydraulic upgrade. I found a way to mount my bender on the cherry picker frame and use the ram to bend the tube.

You can cap one end and fill the tubing with sand. Make sure you tap the tube occasionally with a rubber hammer to compact the sand, then cap the other end. Duct tape the caps as well, then bend. Works very well and you don't have to wait for it to freeze or have to worry about rust down the road.

Never got the sand trick to work. Not wetting the sand or dry tapping with the hammer. Not to mention the fact that a 20' stick of DOM, full of sand isn't fun to maneuver.

sand trick is a joke. it does work sometimes, but is not consistant. better off buying a bender meant to do the job than to try to rig one up that is simply not up for the task.

The problem is the bender dies are not made for tubing, they are made for pipe. Pipe and tube have different measurements, tubing is measured outside diameter, pipe is inside. So 2" tube is 2" outside while 2" pipe is 2" inside.

It is more the way it bends the material. a proper bends pulls the tube around a die to keep a uniform bend. the HF style pipe bender simply pushes the tube in a simple spot creating a pressure point, therefore crushing the tube instead of bending it like it should. even with proper sized dies, the HF style will not give the same quality bends of a proper bender.

Yes but part of the reason the tube bender works better is the die is the proper width so the tube cannot expand as it is bent, if the HF bender had that it would not kink the tube as badly. The extra width of the pipe size allows the tube to spread out as it is bent.
