For me, it started with watching pirate movies, used to love the action, the sound, the big muzzle flashes. Graduated HS, went in the Navy, served on the Ticondroga in Viet Nam, and we would have firing exercises...those big 5 inch guns going off, the deck would shake and vibrate, such a gigantic sound, long flame shooting out, and almost knock you off your feet! That was the start, and now I find myself looking for anything that will make a good barrel! ( good, not fair, safety first!) First one I made was a 24", 2.25" bore, and now I have 3 mortars, 2 @ 1", 1 @ golfball, and making the 4th, which will have a 12" X 3" tube, on a CSA bed, and so goes the journey! Once hooked.....!
