	[* black] Parts:
	[* black] 2 12 hole 1/2" tubes
	[* black] 3 1" x 16" threaded rod
	[* black] 6 1" washers
	[* black] 6 1" nuts
	[* black] Put the two upright on either side of the frame near the cylinder as shown.
	[* black] Put threaded rods through the bottom hole, 4th from the bottom hole, and top hole of the uprights. Do NOT put any through the top part of the frame since it needs to be able to move up and down.
-	[* black] The uprights make sure the bottom and top stay in perfect alignment so the nuts have to be very tight. Use 150 ft-lbs of force when tightening ~~them~~.
+	[* black] The uprights make sure the bottom and top stay in perfect alignment so the nuts have to be very tight. Use a hydraulic system to open the ironworker all the way and then use 150 ft-lbs of force when tightening these 3 bolts.
