Back burnered. Shortly after my last post, in Aug, the XS60 world turned upside down. Been adjusting to the new conditions since. No real time for my own toys, right now. Just some puttering, if I keep it simple.Steven is building what I had hoped to, to a very large degree... we'll get some numbers before deciding whether MSP fits his needs (it might not).
Guys, the now defunct MM Vendor gate contained the Owner's Thread that had this tutorial on valve seal problems/ring replacement in it, I am putting it here for future reference:"Pull the 3 actuators from the valve body, so you don't have to fight pulling the valve. Wrestling with the valve with those in place can sometimes cause damage.Grip the valve stem with padded pliers (I use leather), and take the nut off. It's staked, so you may have to take a bit off... but try to see if the nut will pass first.Pull the valve apart, and look carefully for scratches or burrs on the stem... then roll the stem on something flat to see if it got bent. At this point, it can easily be polished (good for consistency).Re-assemble using thread locker, and re-stake if there is enough material to do so. Be sure the spring is not compressed into a shorter length (it is needed to keep the valve closed until pressure takes over)... this can happen if force is used on it during dis-assembly. The springs are pretty soft.If the valve operates smoothly (with a touch of lithium), it's ready to re-install."This applies to all variants. Please follow it carefully, as getting rough with the dis-assembly could cost you your gun's function... by either compressing the spring to a point of resetting it to too short, or nicking the valve seat. The former can be fixed, the latter cannot.
Guys, I run into new guns, all the time, that won't seal at first. I lube, then pump them very quickly to get the ring to seal once, and that pressure settles the ring. They function from then on.
