Hello John
?
The photos are loaded on the website under Rod's Photos which is my build. Uploaded when I initially purchased the saw approx 15 plus years ago. I originally purchased two?of the cylinders on surplus.com & sold one of my kits to a group member. They were never available after that which was disappointing because they cost $20. The function is acceptable, my blades have a good longevity & great cut quality. I am very happy with my saw, its treated me well. I love all the clever mods everyone comes up with.?

Here is my shelve stand for my saw. I set it upside down to make the bottom of the shelve a coolant drip tank. Just welded up the seams to make it water tight. I never installed a coolant system but it is ready if I decide to add it. Been cutting like this for fifteen years with bees wax. Hope this helps.

I know you have your cylinder already Dave but for others contemplating fitting hydraulic downfeed you can often get a pneumatic (air) cylinder for nothing from a local process plant that they throw away because they can't be bothered replacing the seals. Seals don't have to be good to work in this application
Most plants processing anything from metal to food use air power for control and regularly trash old air cylinders.?
?They're rated to 10bar (150psi) so anything over 3/4" diameter and 4-6" stroke will work and they'll work on oil as easily as air - jv
?
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.
Dave
