Valve body out of aluminium, the seat made out of stainless and I will use stainless for the opposing valve pin seat too.
My plan is to make the pin out of a screw driver shaft and then use valve grinding paste to bed them in with each other. That's the plan. I could make the whole pin and seat out of stainless, but I wasn't sure how well it will handle being struck by the hammer, where the screwdriver shaft is hardened.

After a long break from doing anything creative I have started on a new pistol build. This time I am making the valve differently. After some advice from fellow gunners and also copying a proven design I started.
Instead of trying to form a good seal on a surface within the valve body I am making the valve seat out of stainless and it will sit in the body, but can be removed/replaced if needed. You will see in the photo an FX Bobcat valve stem and seat, and next to it my valve seat with O ring groove cut into it and the valve body behind. Next stage is the valve stem with sealing surface.  |
