Coplaner Jig

You'll need a coplaner jig. This is made from a length of 2x4 and a scrap piece of plywood (or anything that works to keep it vertical.

You'll cut a slot in the plywood, being careful that the slot is perpendicular to the edge of the 2x4.

My coplaner jig uses a triangle of plywood at the base to guarantee that the 2x4 is exactly vertical (despite the perspective of the photograph).

The height of the coplaner jig depends entirely on the height of your press. The pipe should be horizontal to the ground so that when you press the second end of the strut, it doesn't lift the jig off the ground, nor does it result in a bent end of the pipe because the jig was too high. The jig must be the right hight so that the end of the strut to be pressed is in full contact with the bottom block of the press, with no gaps at the near or far end of the section to be pressed.
