4-45* bends, what method?

[4EyedTurd]

I'm building a trans crossmember out of 2" pipe. I'm going to put 45* bends at the ends. I don't have a bender but I've got a torch and some sand and I've read about the having nice bends if you fill the pipe and bend it. Either way, is it worth attempting this way or buying a bender for this one project? Here is a picture of what I'm going for

I assume you meant tubing not pipe.

if you have a oxy/act torch set and welder, you can do it with a junk brake rotor.

pack the tubing with some sand, weld one end of the tubing to your bench, shim up the rotor so it's right at the center of the tubing, weld the rotor to the bench. fire up your torch and bend away.

it has been done this way for about hundred years.

You could cut the tubing at 22-1/2 degrees, and have mitered corners instead of bends, if that would look OK to you

Just be sure the sand is dry before you do this. If not, put it in a pan and dry in the oven. Weld a plate on one end of the tube, tap it on the table or ground till it settles, add more sand, tap again, repeat till it holds no more sand. Then weld a plate on the end and it is ready to bend as described above. You can probably find a Youtube video of this.

You're going to need some really good gloves if you're going to heat that pipe and bend it by hand.


What's this trans mount for ?

How heavy of gage tubing? I hit a muffler shop up and hand them some extra coin around closing time.

 

[4EyedTurd]

Sorry its pipe not tubing and it's kinda thick. Which brings me to another issue of not having anything solid to hold the pipe while attempting to bend it. I'm pretty sure I answered my own question.

I bend pipe packed with sand all the time with my HF bender. I use wet sand and don't weld the ends together FWIW.

difference between Pipe and Tubing:

Pipe: to transfer materiel, measured by the ID(inside diameter), major failure concern is bursting from inside out.

Tubing: to be used for its structural strength, to carry load, support weight, impact. measured by the OD(outside diameter) and wall thickness. major failure concerns are: compression, torsion, shear, bend.

so, you do NOT use pipe to support weight. yes, tubing can be thick. some DOM can be really thick compare to its diameters.

I would just figure out what you need and have a shop bend it for you. I would bet they would not charge much if you know exactly what you need and don't waste any of their time. Maybe go in first thing Monday morning and see what their week looks like and ask them about it. Of course have everything ready before going in.

It still depends on what you are using though. Muffler Shops may be able to help you out and if it is a dead day then they may not charge that much.

I'm curious where this photo came from and if the OP has ever done any fab work or welding before.

Not true for sanitary tube.

The picture is from another forum. It's a transmission crossmember for a F350 with a cummins and NV4500. I've done the swap but modified my original crossmember to work but I don't like how it turned out. Yes, I've done fabwork. Do I own a pipe bender, No.

If you really are using "pipe size tubing" then buy the HF kinker from Craigslist or just get the new one from HF, it will work fine on real pipe size material especially under 90*.

Or you could add your location to your profile and someone might offfer to bend it for you for a 12 pack.

Cool, I was hoping this wasn't for some riced out honda that you were going to use some el cheapo 110V stick welder on.

Not true for sanitary tube.

It is also not true in the power industry with boiler tubes, condenser tubes, or heater tubes.

In general the biggest difference in pipe vs tube is how it is measured (OD vs ID)

cool, why not nuclear.

Ouch, feeling the love man.

Nuclear is also the same

case and point, make sure you don't use pipe to make this thing, good luck on bending some pipes without cracking.

tubing can be round, square, rectangular, oval(aero). so, if you don't want the hassle of bending it, you can definitely make it out of square tubing.

6 inch pipe can be bent 90 degrees without cracking, as can the sizes smaller than that. I once maintained a 6 inch mandrel bender, and saw thousands of bends made. The machine would provide digital readouts of wall thickness, both before and after a bend. These were hard 90 bends, not sweeps. I have a ratchet type hand operated bender in my home shop that will bend up to 1 inch pipe just fine.
