If needed, you can perform a three-step bend. I thought of doing this in Fiberglas, but I think a nice polished bar would match the bike better. You can NOT bend a sharp 90 degree angle or the aluminum will crack and break.Heat will help, but it will also weaken the metal. You can find your bend allowance with the following formula: (π/180) x B x (IR + K x MT) = bend allowance (BA), where B is the angle complementary to your desired bend angle (1 to 180 degrees), MT is the thickness of the material, IR is the inside radius, and K is the K-factor. I will be trying to make this over the summer!! Weld a nut on a piece of steel, then with the help of a magnetic square adjust and weld at the back side of tube, at the point behind of the first guide. using a countersink or a bigger drill bit, do the first hole conical. Aluminum is a lightweight metal with a strong weight-to-strength ratio that makes it useful in many manufacturing processes from auto aftermarket installations such as roll bars to the construction of hiker backpacks. Make a handle of square tube 20x20x1.5mm and mount onto the base at a 140°~150° angle. Mount a piece of angle-iron, in the vise, Place the steel into the angle-iron, so as the cutting point to be just next to end of the angle-iron.
