Homemade Rebar Bender
Rebar can be bent into right angles like these with a simple homemade bender. (wheelbarrow on rebar image by Derek Abbott from Fotolia.com)

Rebar, or reinforcing bar for concrete, comes from the manufacturer in diameters from 3/8 inch to 1-1/4 inch and lengths up to 20 feet long. The large sizes are used in heavy construction, and most do-it-yourself projects call for shorter lengths of the small diameters. Some projects require lengths of rebar that have been bent into an L or at another angle. Rebar benders are available to rent for this task, but a simple homemade bender can save the expense for a few bends in small-diameter (3/8- and 1/2-inch) rebar.

  1. 1

    Measure the rebar with a tape measure to locate the point of the required bend. Mark the point with a band of masking tape.

  2. 2

    Slip the long end of the rebar into a 6-foot length of 3/4-inch steel pipe lying on the ground or floor. Slide a 4-foot length of 3/4-inch steel pipe over the short end and adjust the rebar so that the masking tape marking is at the gap between the two pipes.

  3. 3

    Stand on the longer pipe, or have an assistant stand on it. Grasp the short pipe near its far end and lift, bending the rebar to the specified angle. Use a framing square or protractor to check angles where precision is critical.
