Notes:
I got my sheet brass for the guides from MSC 1 800 645-7270 The air cylinder is 1 1/2" bore 10" stroke. The rod must have a 3" extension I used a Norgren K71EAOO-K56-KA2 for the four-way valve I did not use the anvil clamp at the bottom of the anvil base, I just welded the anvil to the main base I did not use a upright base that is shown in the original plans I welded the I-beam to the main base. Any where that the original plans called for 1/2" bolts, I downsized to 3/8" bolts. I used grade five on all fasteners. I used a Norgren mechanically operated 3-way valve instead of the ball valve used in the Kinyon plans. The part number is K41EAOO-KS1KPO. You will need to plug off port 3 on the valve. I have the valve hooked to a foot treadle. I feel that this valve gives a better range of control than the ball valve.
