HOW TO MAKE A UNIFORM OR DUPLICATE BEND
This is a simple bender. It can be made for any type of curve. In busy architectural shops you may find hundreds of these lying about. This one is made on a piece of angle so that it can be clamped in a vise or edge of a bench. The original curve can be bent hot or cold, by eye, on a wooden form or to a template. The material is mild steel and is arc welded. You could also weld a shank on it to fit your hardy hole.

Two Scroll jigs. The first was used to bend 7/16" square, the second 3/8" x 1" flat bar. Notice that the second jig is two stage. When using both these jigs the ball, bean or scroll end is forged first and then the long scroll bent. These work on plain or tapered material.
The little universal bender above was shown to me by Peter Lindbergh of the Longship Co. The two identical parts are clamped in a vise adjusted to suit the current job.
The bender above is one of several sizes made to make ends for straps using a pinned connection. It is one stage in a multi stage process. Oblong holes were first machined in the blanks. Then the tight bends with critical tolerances were made in a simple press. The bender was the last stage before welding. It was used to produce the long and the tight (pin) bend. The finished parts are now on an oil drilling platform in the Gulf of Mexico.

The benders above were found in Josh Greenwood's shop. Some are mounted and some are not. The unmounted ones are simply clamped in a vise or to a bench. To get the necessary height for starting scrolls he forges a fishtail flare before scrolling. The smooth taper also helps produce a smooth spiral as the thinner material bends easier than the thick.
