"If you turn the box sideways - You might fall out! Then all of your thoughts will be ...." ???
Are you perhaps referring to the phrase "thinking outside the box"? Otherwise, i dont know what you're talking about. I feel a bit offended here. Tell me i'm wrong...
Anyway...Eric...A second lead screw is one thing i will consider on my second machine. Right now i do have a double lead screw with a spring in between. More or less what you mentioned.
Thanks,
Ed.
