I do believe that once you create the hydraulic pressure, the pressure is still there after the epoxy sets...........
but that is just me.......... and if you can't disprove it through scientific methods.... well just let it be...........

Hydraulic, by definition, is fluid. Once a fluid becomes a solid it cannot, by definition apply hydraulic pressure.
1)Take your car and raise it a foot off the ground with a hydraulic jack
2)Solidify liquid inside
3)If you drilled a hole into the case of the ram, would it release 800lbs of pressure at you? Considering there is very little to no air in a properly functioning ram and the supporting material can no longer apply pressure, the answer is no. Since the material in the ram is no longer liquid, the car would not drop either.
Can you raise or lower the jack now?
Solids can expand and contract depending on temperature but, with wood being as malleable as it is, I don't see the minimum contraction and expansion of metal or remaining moisture to be much of a factor with the temps we are talking about.
I just made all this up and hopefully no one will know the difference....
