1) Gather all necessary supplies: 0.25" round mild steel stock, ruler, sharpie, hacksaw, 1/2" R radius pin, locking pin, 3/4" wrench.

1) Read and understand the terminology section of the wiki.

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.)

2) Gather all necessary supplies: 0.25" round mild steel stock, ruler, sharpie, hacksaw, 1/2" R radius pin, locking pin, 3/4" wrench.

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.

4) Using a ruler and sharpie, mark the middle point and make a mark 1/8" from each end respectively.

5) Insert the 6" rod between the radius and locking pins. Tighten the cam such that the 1/8" mark is tangent to the radius pin. It is a tight fit so rocking the locking pin back and forth may be necessary to adjust properly.

5) Insert the 1/2" R radius pin into the center hole and place the locking pin in the 2nd closest hole.

6) As needed, use the 3/4" wrench adjust the adjusting bolt such that the locking pin does not interfere with the path of the forming nose. The middle position should work.

7) Bend the rod until the center mark on the rod barely touches the radius pin. The rod will spring back so a slight over-bend is necessary. You should have a p shape with a gap. * 

7) As needed, use the 3/4" wrench adjust the adjusting bolt such that the locking pin does not interfere with the path of the forming nose. The middle position should work.

8) Repeat step 5 for the opposite end with the p shape facing the forming nose.

9) Bend the rod until the center mark on the rod barely touches the radius pin. * 

9) Repeat step 5 for the opposite end with the p shape facing the forming nose.  

10) Since the forming nose is applying a force to the nice p you had, it will be slightly deformed. To Fix this, simply put the deformed side around the radius pin and re-bend it until you are satisfied with the shape.

11) Reset the space.

<nowiki>*</nowiki>  If the rod slips loose during the bending process try tightening the locking pin and adjusting the location slightly. If the issue persists try clamping the center of the rod between the radius and locking pins and bending about this point.
