Simple Bending Jig

Here’s a simple bending jig I’ve come across by David W. Wilson:

A thick steel plate and large bolts will handle heavier bending. However, a plywood base may be used for lighter bends. The steel plate base is easily assembled if the holes are threaded. But bolts and nuts will also work if held top and bottom through drilled holes in the plate. Various sized sockets from a socket wrench set adjust the radius of the bend. A metal strap may be used to hold the socket in place, and to help keep the bolts from twisting. Smooth bolts and sockets are preferable to threaded rods for the threads will damage the work piece. This type of jig can be held in a vise, or bolted to a work table. A large flat surface around it can help keep the bends flat.
The distance for the work piece between the bolts and/or socket should be snug to keep it from slipping. Several holes drilled into the base at various distances facilitate making numerous radius bends.
“S” type bends are easily bent with this jig. A long rod will help give leverage for several S’s. They may be bent by: 1. Inserting the end of the rod and bending the top part of the “S” 2. Work this bend back through the jig reversed, then bend the bottom of the “S”. Cut hook from section of rod, repeat. Scrolls are also easily bent by gradually working the work piece around a bolt or socket. For repeated work, it’s best to match it to a master shape.
just want to see if i could get some help making simple pan brake for home use
How can I radius 3/4″ Stainless Box Section without sending it to a specialist firm ??
Thanks I’d appreciate anyones comments,

Hi
how can i bend sq tube easy way
What would the bend allowance be to calculate the blank size of the Stainless Steel Rod prior to the bending:
.125″ diameter Stainless Steel # 304 Solid Rod.
Radius of bends = .5625″
I have a length of 4mm stainless rod and want to make two loops in the length to act as a spring for a model aircraft undercarriage.If I heat it to assist the tight bend do I let it cool naturally or do you plunge in cold water.
i just wanted to know what a BENDING JIG was for my homework!
didnt really tell me!!!
I would like to make a jig that will bend 16×3mm mild steel strip to a radius of 300mm. This does not need to be very accurate, but must be repeatable as I wish to bend a number of lengths in order to make some metal railings. Are there any simple jigs I can make or reasonably cheap ones to buy?
Thanks for your help.
