anybody have ideas on constructing a cheap temporary net post or system for indoor play? I have access to an indoor racquetball court that would allow me to set up a net as long as I don't drill any holes on the walls or floor, or leave any permanent marks. plus, I wouldn't be able to store the net system at the building of the racquetball court. these restrictions prevent me from using a solution that I see several local badminton clubs use who rent time at school gyms, but can't afford to buy real net systems. instead they use two wooden sticks nailed into an upside T, which are held up by the tension created by the net's string that runs through the top and that is tied down to the bleachers or some screws on the wall that the school drilled for a different purpose. Yonex has a Mini Portable Recreational Net System (USD$ 100 online) that is not tournament size. Collegiate Pacific sells a base (USD $45 online) and telescopic pole (USD $25 online), but its too expensive because I have to buy two of them and also add shipping costs, and the customer reviews for that company's products are uniformly poor and hostile. various companies sell indoor volleyball poles that roll away on wheels, but cost over USD $250 each and they wouldn't fit in a car. currently, my temporary solution is using two pieces of long wardrobe shelves, leaning them at an angle against wall to hold down the strings on either side of the net, and holding the nets and shelves in place with weight lifting weights at the base. but the net is very sensitive to any strong hits to the net, when the whole assembly falls down easily. I would love to just buy a cheap system, or to construct a better one, for less than USD $100 somewhere online. any ideas? I can't believe how much time I have spent thinking about solutions, but then my friends and I would have a badminton court all to ourselves!
