Hi George

The towers will be clamped/screwed down on a base. The tension on the hot wire would certainly pull them over. The main reason I chose this design is that I have quite a small workshop so when not in use I can store them away. Once I've built this one I'd like to do a cnc router but I'll really need to work that one out, with the space I have. Problem I have is that a lot of space is taken up by 10 radio controlled planes of different sizes and I have 2 kits that I haven't even started yet.
