I made some clubbells
there are some pictures
They are about 2 feet long. I tried to put a shoe, some bananas, and my hand in there for some perspective. They are hollow right now. they weigh in at 11 pounds right now. i can easily fill them with sand to get pretty heavy, and then lead to get really heavy.
one's made from a 1.5" by 12" nipple, a 2" by 6" nipple, a 2" to 1.5" reducer, two 2" closed nipples, two 2" couplings, a 2" cap, and a 1.5" cap. the 1.5" handle is pretty wide and really works your grip when you start swinging these. it cost me about $50 to make it. i could have made it cheaper, but i was able to make it reasonable top heavy by making it this way without making it too long that it would hit the ground. plus, i can unscrew them and make one big club.
i straight up sat on the floor in home depot and put this together there. i took the pieces out of the packages too. once i had my model, i just grabbed the same pieces for the second club and had them double it at the register.
