hey guys.

i want to make a clothes line like this,http://bp3.blogger.com/_jRSOlQdv-ks/...-h/May+005.jpg
except i'll be making it out of 1 inch square tubing.

i remember we had one of these when i was a kid, and it used some kind of pulley system that i don't remember the details about. After I make the basic clothese line like the one above, what route should i go for stringing up some lines? i was thinking about welding a several eye bolts to the thing. But I know when you put wet clothes on the line they will sink down close to the ground if you don't have a pulley system to crank that line tighter?

any suggestions on what to buy from home depot? thanks
