This project requires nipples of steel. 3 of them. And a wrench.The main vertical bar
One 3/4" by 12" steel nippleThe handle
Two 3/4" by 5" steel nipples
One 3/4" steel T-joint
Tape (so your hands don't get destroyed by the threading on the pipes) OR
Gloves (so your hands don't get destroyed by the threading on the pipes)The base
One 3/4" steel floor flange
You can use galvanized steel if you're fancy, but I went for inexpensively hardcore with black steel. All told, $11. For me, the floor flange was the most expensive component at $4.50 from Ace hardware. The T-joint and the five-inch nipples each cost about $2. (Compare that to buying several different-sized kettlebells at around $60 a pop.)
I already had some tape on hand, but if I were to do this again I'd throw on some of that rubber handle-coating stuff that they sell to restore damaged tools. Plastidip
. I would also use something to keep the bottom from flying off. Not that it did, but after doing some swings in a room filled with giant mirrors and a sliding glass door and cabinets full of fine china*, I got to thinking that maybe I should do this someplace with cinderblock walls rather than inside of my apartment.
Given how this device is to be used (repeatedly heaving it into the air), I recommend using a wrench to really tighten that floor flange. Seriously. Maybe use some Loctite or JB Weld. Something that will keep your weights from flying off the handle. Also, use it someplace where nobody is standing directly in front of you. And where the floor is sturdy. If you're a member at a grimy boxing gym with brick walls and a plywood-covered concrete floor, that'd be perfect. I make no promises that you won't get kicked out of a 24 Hour Fitness for using this.
*I don't actually have any fine china. But I do have a television that I quite like, so no more kettlebell swings in the house.
