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.
