Bending Aluminum tube
How do you do it and not kink the tube? I've used those little metal coil spring bender things, but they always end up kinking, anyway, and the tube gets stuck in it. Am I a moron?

Copper wire works well for me . . . a bit smaller than the ID of the tube you're bending and preferably the vinyl coated strand wire rather than solid core. The vinyl "GIVES" when you try to remove it from the bent tube.

I`ve had success with using solder inside the tubing. It bends real easy.

If its alluminum you can heat it up and *with some gloves* bend it to your liking.

I know one of my buddies in engineering classes was taught to fill the tube with sand and cap the ends, then bend it. Kept it from kinking nicely, and was pretty cheap.

I heat the tubing with a butane torch and let it cool, when it's cool its soft as butter. If you need it hard again, just heat it and cool it quickly in some water.

Cap the ends with some white glue and let it dry. It usually does a good job of holding the sand inside.

the heating process of aluminium is called anealing, basicaly you re arrange the molecules of the aluminium making it a bit more maliable. i think the temp is about 470 deg celcius, but the best way is to rub a bar of soap onto the aluminium and when the soap turns brown you have reached the temperature needed to aneal.
