How to Build a Manual Roll Bender

A manual roll bender is a type of tool that you can use to put a bend or curve into a section of metal tube. Metal that you can bend includes copper tubing, or metal conduit, for plumbing and electrical work. To do this pulleys are used to route the tubing through the tool. The action of the pulleys forces the metal pipe to bend as successive passes are made though the device.

Things You'll Need

2-inch angle iron
Tape measure
Chop saw
Felt-tip marker
Drill press
Bolts
Nuts
Socket wrench
Metal pulley
Post bracket
Handle
Epoxy

Instructions

- 1
  Measure a piece of angle iron to 12 inches using the tape measure. Cut two pieces to this length with the chop saw.
- 2
  Make a mark on one side of the angle iron every 3 inches with the felt-tip marker. Drill a 1/4-inch hole into each piece of angle iron with the drill press.
- 3
  Place the pieces of angle iron together, and align the holes. Insert a 1/4-inch bolt into each hole, and tighten a nut using a socket wrench.
- 4
  Measure 4 inches from each end of the angle iron, and make a mark. Drill a 1/8-inch hole through each side of the angle iron.
- 5
  Run a bolt through one hole and through a metal pulley. Tighten a bolt onto the end of the bolt. Repeat this step with the other hole.
- 6
  Position the center of the angle iron over the post bracket. Drill a hole through the post bracket and the angle iron. Secure the pieces together with a bolt and nut.
- 7
  Measure 1-inch down from the top of the post bracket. Drill a hole into both sides of the post bracket.
- 8
  Secure a metal pulley to the post bracket with a bolt and nut. Attach a handle onto the bolt. Apply an epoxy onto the bolt to keep the pulley secure. Allow four hours for the epoxy to dry.
