Homemade Nail Gun

I had to make modifications to the back end of the valve because the valve became damaged due to excessive moisture content, I had to cut off the back end completely to make changes. Changes were made both internally and externally, you will now be able to hold air for an even longer period of time without having to worry the air will damaging the valve. I now have the ability to completely turn off the air flow from the holding chamber so the valve in the back end won't be damaged.
