Has anyone ever used the pipe bender that harbour freight sells. It has a 12 ton bottle jack and dies included. If so does it work on DOM tubing well? Just curious if it's worth the money for me. Thanks

Save your money......those "are made for pipe"......by looking at the design, I can tell you it would make a very poor bend in pipe.......And......It will kink roll cage tubing.......

Totally worthless for race car construction.

Good Luck,

Snowman is right, only a tubing bender will work for tubing, a pipe bender is completely different. Save your money.

Listen guys dont mean to bust you bubbles but I purchased the pipe bender that harbor freight sells 4 years back for $69.00 12 ton with 1/2"-2 1/2" bending dies and it does a **** good job on bending the .095 or mild steel black pipe.

If you dont know how to set the rollers you can crush your bends but if done right you can do an excellent job with this pipe bender.A Wire welder is a blessing to especially the lincoln 175 mig.The gasless wire welders in my opinion are junk unless your just going to tack weld with them.

Take care.
Steven.

steven is right.....kind of.....if you use the smaller dies(1.25" on 1.5" tubing, etc.) and move the tube several times as you bend it, you can get some "acceptable" bends in thicker tubing. the drawback is it takes forever to make a good bend and the radius' are hard to repeat. i had one and it just annoyed me!

I don't know why he's mad.......after all, I'm the one with the busted bubble...lol

Hello Ohiodirt. Personally, I agree with Racerguy500.....you know, the part where he says "snowman is right"......lol

Seriously though, bending metal, is in some ways,a bad thing.....the outside is streched and the inside is compressed......putting alot of stress on the piece.....nothing to be done for it though, so we live with it.

A properly designed die set fits the tube very closely and controls the distortion......the dies completely surround the tube and FORM the bend.....If the backing die does not completely suround the tube,(as in the case of the bender in question) the backside of the bend will flatten....and the inside will likely wrinkle.

Look at the bender. The rollers (dies) do not meet this criteria. They are the wrong size. They do not follow the radius of the main die.(which is also the wrong size) They do not surround the tube.

It is quite impossible for this bender to make the same quality bends that a properly designed bender will make.

Yes, It will make a bend of sorts.....some would call this an "acceptable" bend, some would call it a "**** good job" or even an "excellent job"......others may say "totally worthless for race car construction"......Your decision......but it's an important one........Please choose wisely.

Good Luck,
Snowman

Outlawstock17, I recognise you as a respected forum member. I mean you no disrespect. I also realise that you are only pointing out that the thing can be made to work if no other option is availible.

I just hate to see someone buy this thing to build a car with......I don't think anybody would be happy with it.

Good Luck,
Snowman

Yeah its been a hot topic several times and well discussed.You will almost always get an opinions that differ.Which are good.I would only personally use one for "slight" bends a little teek if you will.Bumpers,a slight bend in a seat cradle and to get that extra little bend in a front or rear hoop.

no problem snowman.....i sold the pipe bender long ago and bought a tubing bender from US tool & die. i didn't have the patience to use the pipe bender, nor did i want to build the whole cage out of 1/4" thick tubing! i could make better bends on an old maple tree in my back yard.......don't laugh! I DID IT!

sideways is correct....it will work for "slight" bends but so will that trusty old maple....

Thank You Outlawstock, I really would not wish to offend you. We post here to help others, and because we enjoy doing so.....
Hard to feel like you are doing a good thing if you have to offend one to help another.Sometimes, I should just keep my big mouth shut......lol

On the other hand, one can not talk about something with out actually talking about it..........and.....of course, opinions will vary.

Steven, I really mean you no offense either, even though you went and busted my bubble.......lol

Good Luck,
Snowman

The single most important thing about bending tubing is the stretch on the outside of the radius. There are specific dies and Slides to reduce the "Thinning" of the metal on the outside of the radius. Without the Proper dies you are taking your life in your own hands by using the Wrong Tool. That being said, spend the extra money and buy the right stuff, or leave it to someone who already has. Yes, you can get by using makeshift benders for bumpers and nerfs - maybe, but never use them for building cages. My opinion.

If you are serious about getting a good bender check out this website. I have used the model 3 bender to bend .095 and .120 wall 1.75 tube and it works very well.

I don't mind the pipe bender's, but only for none safety stuff, Like a bumper and things.
I would only buy prebent bars for the roll bars.
But as stated above a tree can work real well also, a old rear end with a rim on it works pretty good also.
