This was a new cylinder. Was taken apart for modification. This included shortening the cylinder by a few inches, the piston rod, and remachining the threads seen in the photo w/ lathe and manual threading. Gave it new O-rings because it was leaking a little during first test. But other than that, it seemed to have survived…
Until Fluid sprayed everywhere when retracting it for purging air. Extract and Retract was only done a handful of times, less than 5 seconds each. Bolts and pipes were tightened on very well. It is not very usable in the current state.
Cylinder was made to provide 10,000 lbf, maybe the modification affected this? Maybe the Chinese metal was too weak? Would “bottoming” the cylinder out for a second too long have caused this? Any thoughts here?
Figuring this is unfixable, but we are looking to try brazing or maybe even JB Weld for just ONE good run. It’s for a school project, not very high risk
