Just wondering, because the end force on a 1/2" diameter at 3000 psi is almost 600 lbs....

That's a lot of lbs. I am surprised the original survived for thousands of shots as it was before. This fix should be a decent amount stronger than it was. Hopefully an increase in some area being a smoother path for the air to move toward the transfer port. (no setscrew tips protruding)the

Look at how little material was left near the centre. Basically only hairs of brass

It's not the smoothness of flow that is the problem, the rear part of the valve is sealed by two O-rings, one on the OD and one on the stem, so during the shot (albeit a very brief period of time until the pellet starts to move) the back of the valve is seeing a 600 lb. hit, not unlike the blow of a hammer, trying to drive it back towards the hammer.... That is why it survived for a while and then failed, there was simply not enough brass bridging the gaps between the screws to withstand that hammering.... Your solder joint will be subject to the same thing, but if it's long enough and a good enough quality it should last.... depending on what you used, of course....

Hopefully it holds up to the pressure. I'm interested in continuing that string I started before this happened.
