right, so i want to build some sliding shoes this summer to work on balance. i found some wood i have that slides good on pvc. i have a big pvc pipe from my old hockey net. i can get the wood attached easily on my old shoes. the problem is making the rail. i dont know how to attach my 4ft pvc pipe onto my 2x4x4. i know its small, but if it works good ill probably buy a longer piece of wood and pvc at home depot. any help is appreciated.
