I've been wavering back and forth about making my own cylinder or buying it.? ?I determined it would be more expensive to make it because I would have to buy the drill rod, the aluminum, the cylinder, etc. to recreate the Halligan's design.
I saw the hydraulic down feed from SawCyl.? ?I believe that he is using a Parker cylinder:? I talked to the guys at Parker and I believe the SawCyl cylinder is a 1.25DXPSRS04.00 and the part number is 1PSR00010153.? ?I ordered the cylinder from Parker for about $63.? I'll still have over $100 into the retrofit.? ?I am eventually wanting to mount the saw on a rolling cart (a three shelf metal cart) and keep both the spring and the hydraulic cylinder.? The cart allows a great deal more flexibility for mounting the cylinder and keeping the spring.? ?The table is also a great way to raise the height of the saw, control the saw chips and have a place to put your metal.? ?I have a dedicated vertical band saw and this is my dedicated horizontal band saw.
