I would really like to know what kind of pipe/tube this stuff is.
Don't feel bad George, I got it.
We know its not DOM. Call the steel guy and get the proper name.

OK Skipper a guy runs into a bar and goes up to the bar tender and say I heard this really great Polish joke.
The bar tender looks at him and says I'm Polish the big guy to the right of you is Polish and the even bigger guy to the right of you is Polish.

The guy say OK OK Ill take it real slow!

Scotty the term pipe is loosely used for any round metal, this is not an issue most of the time. In your case the HB pipe bender is meant for pipe AKA water pipe. This means it will bend water pipe all day long and pipe is measured inside diameter so 1 1/2" inch pipe will always be 1 1/2" inside and typically 1.900" inches on the outside diameter. That means your bending shoe is designed for 1.900 inches (almost 2 inches).

The stuff you bought is tubing (ERW electric resistance welded tubing)and if you measure the outside diameter it is 1 1/2" if you compare that tubing you are trying to bend to a piece of 1 1/2" water pipe and you will see what I am talking about. There is .400 thousand of an inch difference or slightly larger than 3/8 of an inch!!!!

Your tubing is collapsing in the die (AKA shoe) and kinking because its the wrong die and Harbor Freight does not have the correct dies cause they dont make them.

That is why I said get a piece of 1 1/2 IMC which is 1 /12" inside diameter and it is 1.833" (just slightly smaller than water pipe) cut piece about a foot long then cut the tubing in half lenght wise.

Now take that IMC and place it over the tubing you want to bend. Place the IMC so it is in contact with the bending shoe then bend.

You have now made a shim that will make up the difference from your water pipe die so that you can bend your tubing with out kinking it.

That shim should last a few bends maybe even a long time.

Got it?

Ahh, George... you are Beautiful, Baby!! That is so understandable, and so perfectly said, that even BILL could get it! The Pollocks just cracked me up!!!! What was the rest of the stuff you were talking about?

I got it. The OD is 1.51"; ID is 1.33"; sidewall is .10". ERW... GOT IT!

So you guys don't have to go back and forth, here are some pics. I had deleted them before, and I had to get new ones!



The upper rollers of the bender do not align with the shoe. And when all else fails, weigh the pigs!

Where do I get IMC? The Big City is, like, an hour and a half away!! We have Lowes, Ace Hardware, and one specialty plumbing shop.

Do you have a electrical supply house around? If not try Lowes or Home Depot and see if they can order you a 10 foot stick.

That set of dies must be for something over 2" Scott, maybe even bigger and that's why your material caved in like that. Anytime you do something and have problems always rule out what you know is right first.
1. You are using material that can be bent into the shape you need.
2. The tool you're using is wrong for what you have but if you had the right dies it would likely work.

Something else I'd say would help is if you grease those rollers so they can turn as the material bends. The less friction you have the better and easier the bend goes. When you get the right dies concentrate on making a bend of 90 degrees. Take your time and check it even before the bend is complete, just mark the material in relation to the main die so that it goes back to the same place, which it tends to do anyway but the less variables you have the better. Just take it slow and it'll come to you. It overwhelmed me at first too but after you figure some basic things out you'll be amazed how simple it really is. Oh and quit getting mad at yourself, I can see you doing that my friend.

Thanks Ol Buddy! With all the help you guys are giving me I'm confident that I will figure this out. If not, I'm going to fly George down here!!



Wife and son were sitting at the kitchen table when my son said, "There's something BIG in our yard!" So Mom looked and hollered, "The pigs are out!" Understand that we are a small island in a sea of woods inhabited by wild hogs and much other game. I always figured if the hogs ever got out that the best I could hope for would be a genetic gain in the wild population. In other words, we'd never see them again, and some lucky Yahoo would get some prime meat in his freezer. Would you believe those crazy hogs came right to the porch door!? Beth opened the screen door and they walked right on to the porch. I was able to hook up our little homemade stock trailer and get them loaded. They are safe for the night until I can repair the pen tomorrow. What a blessing. These are the hogs my two youngest will show in the fair in April.
