BUILD A BENDER

An Economical Way To Get the Bends You Want

Bending irons have been used in the industry for many years. We first became aware of how handy they are during a 10-year stint in the can industry.

Why Use Bending Irons for Metal Fabrication

This type of bending is totally portable and can generate tremendous force. While these irons are not good for sharp 90-degree bends, they are excellent for most radii. We made these irons specifically for the 1/8-inch-thick material used while making our convertible top-anchoring strap. We made the jaw sections larger and thicker than necessary for bending 1/8-inch material because the irons will be reworked for 3/8-inch round stock for our next project.

Building Your Own Economical Metal Bender

For our heavy-duty bending irons, we used 3/4-inch-diameter round stock that was 18 inches long. The jaws were fabricated from 3/4-inch-thick steel plates, and we cut and milled the jaws on our vertical milling machine. If you do not have access to such a tool, you can use a band saw or hacksaw and a drill motor to make the slots.

Versatility of DIY Bending Tools

The portability of the bending irons is another plus. When the job is too tough for bare hands and too small for the vise and hammer, the bending irons fill the gap. With larger slots, the irons can be used for round stock, such as the curved framework of the new center console you’ve been thinking about building. Take a look as you show you how simple this process really is

1. For our heavy-duty bending irons, we elected to use 3/4-inch-diameter round stock that was 18 inches long. The jaws are fabricated from 3/4-inch-thick steel.
2. The jaws were cut from 3/4-inch-thick steel, approximately 1-1/4 inches wide by 1-1/4 inches tall. The slots were marked to accommodate our 1/8-inch thick material.
3. The jaw blocks were machined for a slot slightly wider than 1/8 inch. We used the vertical milling machine, but a drill motor and hacksaw will achieve the same result.
4. We used a round file to dress up the edges of the slots in our jaws.
5. The jaw blocks were welded to the handles. Make sure that you get a good weld along the edge of the jaws so that they will not break when pressure is applied.
6. Our new portable bender should be strong enough to handle most of the material that we will be bending. The long arms will give you much leverage.
7. For close radius bends, the bender handles are positioned on the outside of the radius. Positioning the bender handles on the inside of the radius and spaced farther apart can form larger radiuses.
8. The jaws can be positioned at different intervals depending upon the radius of the bend you are making.
