I posted this on another thread in the Open Source forum... but I don't think it is getting much visibility there. I am really curious about peoples thoughts on this. Do you think it would work?.....
I'm going to be using a 1/2inch acme which will be 55 inches long. I'm worried about whipping as well. I devised an idea to stop the whipping, not sure if someone has used it before.
Basically... the screw will have several spring loaded doors on each side.
The hinges will be double action such as this... they bring the door to the "closed" position, but let it swing both directions.

Planning to use a 1/2ID teflon washer of some sort in between and cut in half.
Not sure if it will work, and is just a contingency plan, so I may never know.
