Aluminum flat bar bender?

Is there an easy way to bend aluminum flat bar? Like a device, either
store-bought or homemade? Something other than a simple vice.
Thank you.

A simple vice? Like eating too much chocolate, or sleeping in late on the weekends? ;-)

======== You will get better advice if you can tell us how big the aluminum stock and the type/size/tollerance of the bend/twist, if you can have clamp marks, etc.

REAL men bend it with their bare hands.

Yes, there are many ways to use bending fixtures on bar stock to bend it at any radius you desire - if you Google around someplace like Harbor Freight Tools you'll find several.
But if you don't heat treat and anneal the aluminum bar stock to "dead soft" condition first before you try bending it I can guarantee failure, because Aluminum will fatigue and crack at the bend. Sometimes with a sharp bend you have to anneal it, bend part way, anneal it again, then finish the bend.
With Aluminum there is very little difference between the heat needed to anneal and to melt. You'll end up with some "Oopsies" and a puddle of Aluminum on the floor where you lingered with the torch just a little bit too long...
Which is why it's usually a whole lot easier and faster to cut your bar stock with a miter joint, and TIG or MIG (Spool-gun) weld the pieces together at the angle you want, than to try bending it. Especially doing it on a production basis.

Just in case the entire world doesn't know this trick:
When annealing aluminum with a OA torch, turn off the oxygen and smoke the metal with the acetylene flame. Turn oxy back on, gently heat until the carbon burns off. It should be annealed at that point, at least well enough for bending/forming. Keep the torch moving, especially on this stock.

No. As long as you control the bend radius, any of the wrought alloys are bendable without annealing. The minimum radius depends on the specific alloy, temper, and thickness.
Fatigue is a result of cyclical stress, not a single event.
There may be some exotic aluminum alloy that strain hardens that quickly, but I've never run into it.
If it is necessary to anneal, the temp should be around 650F; the melting point of common aluminum alloys is in the range 900-1100F. See the post by Bill Marrs for one trick for annealing. (As he implies, we're not talking about a true anneal, but reducing the temper enough to make relatively sharp bends.)

Thats a simple vice, right?

Ooh, sounds like Gunner needs to exercise more regularly. Keep things which are to be flexible, flexible.

Sigh...and the things that are to be stiff...sfiff.
Practice practice practice.
Though Im afraid Im going to have to quit smokeing really soon...I started running out of wind much sooner than I should have. Even with a gal sitting on my face.....shrug

See, what did we tell yo?. Those things are bad for your social life. Like the Sunday School teacher told me "You don't have to smoke and drink to have a good time."
Dang, now I'm wondering if I had stayed on the swim team in school, would the ability to hold my breathe have proven of good use later on? Hmm, the things we'll never know.

Winter? What winter? Haven't you heard about 'Global Warming', where it'll be over 100° F year round?

I've always been bemused by those who will say "it is f*sking cold out!" when the temps are way to too cold for comfort.

I always laugh at the people in a sweater or zipped up jacket when it drops to 65° F around here, in Central Florida. I've been here almost 20 years, yet I rarely wear a coat, even when it dips to 45° F.

Last year, when it spent several days below freezing, we're standing out side for break (midnight thirty if I recall correctly) and someone make a comment about how it's suppose to drop to 28 degrees "tonight". Forman pulls a six inch scale out of his bib overalls, holds it to his chest (nipple) and looking down says "yeah, that's about right!" Sheesh.
