Tips on bending pipe, or making a pack rack thing

[Steam]

I need to put some bars on my bike to stop the soft panniers going into the wheel.
What's a good simple way to bend pipe or box for the home handyman?
It doesn't need to look good, just needs to work.
You can see what I plan in the photos, in red. There are good bolt-holes already there to bolt it to, very convenient.

Thanks in advance for your tips or suggestions!

you can get small pipe benders from supercrap for less than 20$, all they are is a radius to ben the pipe on.

Or you could just weld it together.


If the pipe is small enough you could just put it in a vice and beat on it.

Simplest and most effective way is to hire a manual pipe bender from your local hire shop. Try your local pipe supplier for hydraulic pipe and bend away happily.

Would those pipe benders from hire shop do exhaust tubing?

Clint640 made some pannier racks for my sherpa from 1/2 inch tube I bought from Hydraulink. http://www.advrider.com/forums/showthread.php?t=274521

We got them powdercoated to match the colour of the frame, and they look (and work) really well.

You can pour dry beach sand into the pipe. Pack it lightly, and cap it with wood plugs.
Heat and bend the pipe/tubing with an oxy set, paying attention to add more heat to the outside of the bend. The sand stops the pipe collapsing while the metal reshapes itself. Great way to make complex header pipes from scratch.
Plus its cool to brag about your artistic bending skills.
An Orange glow on the metal is a sign that its close to bending temp.

You are proposing to some quite tight bends so if you are going to do it yourself you can limit the flattening on the bends by filling the tube you are bending with sand. Just sellotape up the ends and pour the sand out when finished.

Aha! That's a good tip. Cheers.

So are the others, very interesting things.

Used to use a pipe spring for bending copper pipes - just insert the spring and bend it with your hands, spring wont compress and flatten the pipe.

Nope, not old. Just one of those people who listened and watched their dad when I was a child.

My dad still has his set! So simple but it works wonders!

Naw, pipe springs are still very common, ask any HVAC engineer.

How do you bend your exhaust pipes?

Either make them from stainless mandrel bent donuts and 90 degree bends, or make it any way you like, then have the machine scan what you've made in in 3D, and it spits a mandrel bent stainless bent tube out the other end
