On a side note do you have a tutorial on the turntables I really like the idea and would like to try it on a dio.

Ron, I'm not sure what to say about a tutorial for turntables, other than it is trial and error, and you have to build around them, constantly checking that nothing impedes their ability to turn. You want them anchored with a non-slip mat while building, and if you want to, can glue it in place once you have everything around it done. Just make sure the structure around it is solid, and won't settle, and impede movement, especially if you glue it in place. The turntables I use are about eight to ten inches in diameter and make of plastic. They are also $1 from the dollar store, so cheap to play and experiment with! Hope this helps!
