I was given a great idea when I needed to put in a mast for the satellite internet transmitter. The mast, which needs to be made from schedule 40 2-inch galvanized pipe, is a massive 10 feet tall. To make it easier to handle we cut it into several pieces. That was a great idea until it came time that the satellite dish was mounted to the top, serving as a sail as well the dish has done a better job of tightening and loosening the threads than we ever hoped to. It turned out that we weren't able to use the nifty t-joints we'd put in to run the cable as we'd hoped. Note to self, next time do the one piece mast and save yourself the headache of having to retrofit set screws into the setup.
