I am working on a concrete block Garden bed in a Passive Solar Greenhouse Nursery attached to my home and I didn't want to spend money on a rebar bender. I developed an easy and cheap method to bend 1/2 inch rebar for small to medium size projects. Using two 3/4 inch galvanized pipes I am able to bend it accurately by hand with a little mechanical advantage.
