Thanks guys. I really like how Bob's uses his 2 x 6 wood leverage jack. It's a simple way do press tobacco but you can weigh the amount of water or what ever you use as weight on a scale and you can figure out the applied pressure on the piston too for consistency. The way I'm doing it, I have a feel for what I apply the pressure to the handle of the bottle jack but that's not consistent. I don't put a lot of pressure on it like you would lift the corner of a car to change a tire. But with my press I'm guessing really. Maybe I can figure out a way to rig something up, it would be nice to record the numbers to at least be more accurate. I'm thinking there's a way to adapt a gauge and convert the numbers from psi to lbs. I do have torque wrench also
