So i had some time today to get some more machining done.

I made the adjustable hammer. Everything is 316 Stainless.

My setup is going to be a threaded shaft which screws into the back of the value body which will stick out the back of the gun. the piston (hammer) has a hole in it to slide along the shaft to guide to to the valve. I made a custom threaded adjustment knob..  i just wind the knob in for more power of back it off for less. this will be sticking out the back of the gun as well.

How does actuate the valve?
Being that shaft is screwed into the valve and im assuming doesn't move, and hammer is hollow in the middle to slide down the shaft, im at a bit of loss as to where the hammer contacts on the valve set up to cause the pushing motion to open the valve.
Im looking at it from limited understanding and basing it off a 1322 valve which strikes a central pin pushing the valve open.
What am missing/ not seeing in your design?
Love the pics with lathe in motion. Brings back memories from yesteryear.
Very envious of you guys who set up a permanent base and set up with the tools to make use metal.👍

So the shaft screws into the housing just above the valve. the hammer slides down the shaft and hits the Valve

Gotcha. The valve is off set from the center.
Which i assume is part of the reason it has a central guide. To stop the hammer tilting as it hits. Cheers
