Roadrunner, can you help with the tube dimensions, the ID/OD of the brass sleeve insert one and ID/OD of the SS outer tube? Where you bought/found them?
This is simply 3/8" ID galvanized (not SS) steel pipe I picked up from a scrap metal yard in town. The brass is 9/16 ID thinwall tubing that I found in a hobby shop. If you don't have the pipe, you don't need the tubing. But if you do, take it along with a mast and make sure it fits right. As I mentioned before, most people just use their hand, and that's exactly what I did before finding the pipe. The masts have a tendency to bend where they previously bent. It doesn't have to be exact to work. In fact, several users have slightly bent fins and don't even notice.
