Re: Bike Bobber
Now that the arm is fit to the bracket I'm going to set it aside again and finish the bracket. I cut a rectangle out of a sheet of 1/8 in. aluminum wide enough to fit between the bracket clamps. Next I heated and bent the piece over a steel bar welded to my table. Aluminum melts at 900 degrees F, but unlike steel it doesn't change colors when it gets hot and when it cools down.
When heat is applied to the surface the surface will become dull. Just moments before it melts it will get a orange peel texture on the surface and than it will simply fall apart like an old sponge. Sometimes when you mistakenly bend the metal parallel to the grain... opps it cranks. This is a rookie mistake, but it will serve well as an example of what not to do.
