After travelling to train shows and seeing what others are doing and how they hold or join there modules Ive just used what I think is the best and easiest!
Basically the screw in legs allow easy change of height, all though the metal nut is in the wrong side the idea still works screw it in the leg gets shorter, screw it out and the leg/height of the module gets higher!
Making it this easy means less time trying to align track and correct height differences when setting up!
Then all you do is just use a basic largish clamp between each module to keep them all togther and make them stable.
