The primary arms attach the cylinder/frame assembly to the secondary arms, which support it. They also attach to the plate which holds the recently pressed bricks, and the support plate which prevents the dirt in the drawer from falling out of it.

Tools Required

Hole punch with 13/16" and 3/4" dies

Materials Required

  • 2 pieces 72" long - 4"x6"x3/8" angle steel

Fabrication Steps

Punch the holes on the 4" side of the angle iron first, all of them 1 1/4" from the edge of it.

  • The 3/4" holes are located 2" and 70" from one end of the angle iron. The two arms will be mirror images of one another. (These holes are slightly smaller than the others to minimize play between the primary and secondary arms, preventing extra vibrations on the frame.)
  • The 13/16" hole centers are located at 15", 31", 37", 39 5/8", 48 3/8", 53", and 64" from one end of the angle iron.  Make the two arms mirror images of one another.
  • Determine which one is the right arm, and which is the left by looking at the model and label them.

Then punch the holes in the right arm for the plates. The holes for the grate mounts will be torched later.

  • These hole locations are all 1 3/4" away from the edge of the iron, and their diameters are 13/16".
  • They should be 9", 13", 18", and 28" from the end when the arm is in the right position (see model).
