Fabrication Steps
There are two primary arms, one from each 6' (72”) piece of angle steel. The arms will not be identical, as the left arm will have no holes punched on the 6” side whereas the right arm will need holes punched on the 6” side. The holes for the grate supports will be torched in place. The only difference between the "normal" and "monster" arms is the location of the roller slot.
- On one piece, mark holes on the 4" side, all 1.25" away from the edge for:
- Two total 3/4” diameter holes at 2” and 70.”
- Six total 13/16” diameter holes at 27", 37", 39 3/4", 48 1/4", 51", and 63 1/2".
- Use this piece to mark the locations on the other side. They are to be mirrored, so make sure they aren't in the same exact orientation.
- Determine which one is the right arm and which is the left by looking at the diagrams. Label them.
- Punch the holes.
On the right arm, punch the following holes on the 6” side of the angle iron, measured from the left, each centered 1 3/4” from the long edge:
- Five total 13/16” diameter holes at 9”, 13”, 18”, 28”, and 30" inches.
- Also, torch the hole for adjusting the rollers at 45". Its shape is shown in the diagrams.
- Torch the roller adjustor hole in arm B, 45" from the right, so the holes will be at the same frame location.
