ok, this might be long so bear with me. i got a 1/2" power drill. made a small platform on the side of an old cabinet in my garage using 2 L brackets on the top and bottom for stability. sat the drill on that and got a piece of flexible sheet metal (about an inch wide) with holes across the whole piece at lowes for about $6.00. the piece is about3 ft. long. you will only need about 8"s of it. bend the metal around the drill body and drill holes in the cabinet to attach the bracet onto. using the the bolts, tighten the drill on, make it snug so it won't shift but if you go too tight, you will actually slow up the motor inside the drill, a lesson i learned. get a 8" green flower pot for about $3.23. mount that on a piece of wood because you will need the stability when the ball is sitting on it. i used 6 bolts to be safe. drill a hole thru the middle of the wood and pot. i found a long thick bolt and cut the head off. grind 3 sides of the bolt that is going in the drill, you will need that done because when you start the drill with the ball on it, the bolt will loosen up if you don't lock it in the drill shaft. put it down the drill shaft till it hits bottom, and lock it in tight, i used pliers. with the threads sticking up, place the pot mounted on the board thru the hole in the middle. use a washer and then a lock nut to tighten it in, if you use a regular nut it will come loose(trust me). i got a extension cord with a foot peddle so i can keep both hands on thball and be able to turn it off quickly. (trust me again, LOL). it sounds tuff but it really isn't, it took me about 3-4 hours to get it right but i could probably make one now in about an hour. the foot peddle is important in case you mess up along the way. total cost about $25.00. you first shot at using it you may want to use an old ball. LOL. good luck and if you need any help, give me a holler.
