Two Problems

[Mr. Chopper]

First, I'm trying to make a pipe, a rather small one (but not microscopic). I can make it ok, I just create a long brush, and change the number of sides to 20 or so. But then the texture I put on it gets all messed up. Second, I added a model of a lightsaber to my map, but it WILL NOT rotate. Angle, angleS keys don't do a darn thing. Massive help needed
