Sorry. <<SNIP>> This is what I get for being computer "STUPID" and dependent. Hey, us Outside plant guys always think that about Inside plant tech's. ;D I hate the look of factory fenders. I have done a few fender mods to my Burgman and with the Car tire on the rear it shows off that big fat tire. In the rain up here you should see the "Rooster tail" behind me. No tailgaters. |

Now that a nice looking trike! Pretty good bending flat sheet aluminum without annealing it. Annealing makes it like soft cheese. The Youtube vid below shows how it works. Aluminum hardens in a totally different way from steel, and is annealed differently too. To harden steel you heat it and quench it quickly. But that's how you ANNEAL aluminum! Tempered aluminum's springiness comes mostly from its alloying elements. After annealing, the hardness will gradually return on its own. Hardened aluminum can be temporarily annealed by heating it to about 500 degrees F, and quickly quenching it with cold water. It will then remain soft for between a few hours to a couple of days (depending on how hot the weather is); gradually regaining its original hardness. To speed up the re-hardening, you can re-heat the aluminum in a 250-degree oven for 2-3 hours or so, Dropping the temp 50 Degrees F every 1/2 hour. (This is called AGING the aluminum, not true TEMPERING.) How to bend tempered aluminum with a propane torch. Use soap (The cheaper the better) or special wax on the area to be annealed. The soap has nothing to do with the hardness, it is only a temputre gauge. Carefully heat the local area you wish to bend. When the soap turns noticeably brownish black, quench the metal, with a heavily wetted cloth or by plunging the hot area into ice water. The faster and colder the quench, the softer the aluminum will become. T-6 is HARD. Annealed is T-0. The T = Temper. www.metalshapers.org/tips/covell/annealing.shtmlwww.youtube.com/watch?v=FxhdFsrzSmY |

Re annealing aluminum, that's a bit too general.
Only some of the aluminum alloys are heat treatable, like the 6000 series; others can only be work hardened.
