New Cricket Valve Spring Lock Nut….by John Hagan
Pretty simple and keeps valve stem from changing positions.
1) Threaded valve lock nut

2) Screws on top of valve stem spring adjustment nut.

3) Adjust valve stem spring tension and put lock nut on top of it

4) The threads are perfect, but use an easy hand when starting the lock nut

5) Never forget to replace the valve on your gun least you sustain catastrophic air loss

That valve gets pounded with each shot, and there is nothing to hold that valve spring in place except friction. Cheap insurance to keep results consistent.
Aerotulz55 is the machinist. I think Ernest has access to them as well.

I’m certainly glad John had the common good sense to develop these inexpensive little lock nuts, because as loose as that valve spring nut is, and with the constant pounding it takes with each shot, it doesn’t take a genius to figure out it WILL rotate towards the direction of least resistance. Pretty soon, you’ve got no power at all.
