You will need a couple things first. A 3/16 drill bit, Loctite Red thread locker, Cartridge Holder (I made mine from a 1" black pipe and a dremel) and a hand help propane torch. You drill the pinged points until you see the threads in the hole. It does not take allot of pressure. Take your time. Be very careful NOT to drill all the way through the cartridge. Once you have all the pinged drilled put the cartridge in the holder. Heat the area where the pings are. It does not need to be red hot just heated. Now unscrew the tube. Be careful not to warp the tube. Once it is apart, clean the threads. When you’re done installing the valve, you will need to use red Loctite on the threads when putting it back together.
Too bad your now closer to Idaho, I would give you a hand.
