Location: Machine Shop
Description
A hand bender is a machine used to bend wire, solid stock, and tubing. The bender comes with multiple dyes for different types of bends.
*Currently the bender stand is not bolted to the floor, so you can really only bend light materials like 1/8" thick aluminum. If you want to bend thicker material, you will need help from someone to hold the table. In the future we will be bolting the bender to a sturdier spot.
Here is an example of bending a piece of rod:

Documentation
Terminology
See the diagram on page 4 of the User Manual for complete terminology and visual reference.
Training
Overview
Read/skim the "Art of Bending" document to find out how to set up the equipment. Then Watch the "Simple Bend" video to see how the equipment functions.
Demonstration
To demonstrate competency on the hand bender you will be required to make a s hook.
General Procedure
1) Gather all necessary supplies: 0.25" round mild steel stock, ruler, sharpie, hacksaw, 1/2" R radius pin, locking pin, 3/4" wrench.
2) Cut a piece of 0.25" round mild steel stock 6" long using a hacksaw. (A hacksaw should be used instead of the horizontal band-saw because the diameter of the material being cut is small enough that only one-two teeth on the band-saw blade will contact the material at a given time. The likelihood of damaging the saw blade or having the stock become caught in the blade increases anytime less than three teeth are in contact with the cut stock.)
3) Using a ruler and sharpie, mark the middle point and make a mark 1/8" from each end respectively.
4) Insert the 1/2" R radius pin into the center hole and place the locking pin in the 2nd closest hole.
5) Insert the 6" rod between the radius pin and the die and tighten the cam such that the 1/8" mark is tangent to the die. It is a tight fit so rocking the radius pin back and forth may be necessary to adjust properly.
6) Using the 3/4" wrench adjust the
Safety
- Keep all hands and fingers out of any pinch points.
- Be aware of your surroundings before swinging the bending handle.
