Use a high strength steel here, or maybe stainless, if its available. (this part is not visible in the above picture).įor the upper anchor pin – 1″ x 8″ steel rod (the stronger this part is the better). To center the roller – 2 pieces of pipe or tubing that will sleeve over the lower pin, each approx 3″ long.įor the lower roller pin support – 1 pc of steel angle, 1/8″ x 2″ x 2″ x 6″ long.
I changed this length to extend the full width of the inside of the bender – 6″ long.
Note: the picture below shows a piece of dom approx 3″ long.
To fit the die yoke – 6″ long 1 1/2″ dia x. For the lower roller pin – 1″ x 8″ steel rod,.For the return spring anchor points – 2 bolts, 1/2″ x 3″ with 4 nuts.For the jack platform and die yoke – 1 pc 1/2″ steel, or 3/8″ steel, 5″ to 5 1/4″ square, 2 pcs 1/2″ steel, 3″ to 4″ x 6″.For the lower cross braces – 2 pc, 1/4″ steel, 6″ x 6″.A pair of return springs – I used tension springs with an approx.For the top cross brace – 1 pc, 1/4″ steel, 6″ x 4″.For the sides – either 2 pieces of steel plate, 35″ x24″x 1/4″, or, (4 pieces of steel plate), 2 pieces at 6″ x 24″ x 1/4″, plus 2 pieces at 4″ x 29″ x 1/4″.So, the list of the materials you will need is: You can easily make changes to this unit, I’m showing you how I made mine, but feel free to change things if you like. The jack is a 12 ton variety, A short jack with a screw extension on top is what you want. The body is made of 1/4″ steel plate, except for the jack platform which is 3/8 ” steel plate. After a few minor adjustments, this bender has worked very well for me.
