I did a little research a while back and found out that you really need a bender that has dies that support both sides of the pipe to get good quality repeatable bends. This is the cheapest ready made unit I found Model 3 tubing bender by JD2
at about 300 bucks for the manual bender plus anywhere from 115 to 300 dollars for a set of dies for one size pipe. The price varies depending on the minimum thickness and what radius you want. If you do a search for "diy tubing bender" you will find people who have made their own with purchased dies and even some who have made dies from pulleys and such.

I found a 16 ton and 12 ton hydraulic bender at HF that are advertised to bend exhaust pipe and solid square or roud stock. they are 159.99 and 74.99 respectively.

When you use the words tube, you exclude yourself from the HF pipe bender.

Water pipe, Yes, does fine, a tubing bender is a different animal though.

Best I have seen or heard of is the stuff from Williams Low Buck tools. Plug that into google and it will bring him up. He also has a very easy to read explanation of why, and what is the difference. His stuff is top notch. I want the tubing notcher in the worst way, just do not want to spend the money.

Anyway, I have the bender from "lockdown securities" who have changed names dozens of times (it seems) I forget what they are called now, and actually, I think I bought it before they were lockdown securities. I have the square tubing 1" die for mine and it works well, but gives you a suck bend.

My dad has one made in Ocala Fl, I cannot remember the name, but it is a dude, and bends tubing really well. I can run down the name if needed.

A Hossfield is the real deal, just bring money.

The harbor freight bender works OK on thick wall pipe such as .125 wall 1" and heavier wall 1 1/2" and 2". I have even used it to do some small(nothing greater than about 30 degree) bends on 1" .125 wall box tube to make a spray tank trailer frame and arched rails which also worked OK. Anything thinwall is going to wrinkle the skin on the inside of the bend radius as the dies are not a tollerance fit to support the sides of the tube and force the stretch/compression of the inner and outer radius sidewalls that are required for a smooth bend. I was going to experiment with a tube packed with sand, but havn't got around to it.

Me too, on both counts. Maybe this current topic will be incentive for one or more of us to try this weekend :)

If you are willing to go to that effort it will work.

Brownells gunsmithing supplies has some lead type stuff that melts at like 150f. You melt that stuff and pour it in, bend it around anyway you want, heat it back up and pour it out.

It is really neat stuff.

On the cheap note, if you know anyone in the hospital supply section, the stuff that is in the package around the radioactive isotopes is supposed to be the same stuff.

I clicked on that link above, I think I have the model 1 and that is the newer updated one, I have the one that HF copied and you can get now for about $70.

Here is the lowbuck I was mentioning / speaking about. Goes up to 1 3/4 or so.

That is the bender I have (the one on e-bay) I know that business sold and moved around a couple of times. Maybe it is one of the "old" guys.

I can bend the 1" square tube, but when you went bigger you needed their #2 I think it was, that had the ratchet type deal leverage multiplier like was shown earlier. The U part was bigger then the original.

While it may look identical, I would be careful that what you are seeing on e-bay is not the #2 with the bigger U piece and the dies are sized accordingly and would not work in the HF one.

Having to jog my memory some here, but these guys are the one's mine is from.

Good stuff.

I don't want to hijack the thread but have a related question: What is the best (DIY) way to bend relatively thin wall 1.5 or 2" tubing (like a curtain rod). The radius would be about 16 feet and the pieces would be about 4 ft long. To help you visualize it is literally for bending finished curtain rods to fit a curved window. ??? any thoughts. I have searched around for the type of tubing benders being discussed here but they are all for making much tighter radius bends. I don't know if this type of tool is what you'd use for the wide radius bend or not. Thanks.
