how to make a cannon work: first, make one of the steam generators conected to the cannon, make sure you put a fuse pipe with 60 configuration, then, put an joint connector, this will be the cooling system, make a pipe out of that joint conector, and put a lot others join conectors instead of 1 block pipe, but stream vent instead of end caps, and there is it, when the fuse pipe activates, the cannon will shot, and the vents will draw the remaining steam, reloading it, thumbs up if this helped!
