Bending steel is not that difficult. You can make a pretty tight bend up to 90 degrees in up to 1/8″ material simply by clamping it in a vise and hammering it over. To go beyond 90 degrees, say 180 degrees for a truss rod, first bend it to 90 degrees, then heat the elbow and finish the bend. Heat the bend point until it glows orange. For smaller (guitar-sized) materials, a common hand-held propane torch should be adequate. After bending, quench the part quick in water, like a blacksmith in a western movie. You can hold a small part under the faucet. That will restore the strength of the material.
