Re: pic: Linear bearing rails: the Cheesy RAWC way

They had two of these mounted exactly as shown, but mirrored so that the inside rails could be connected via cross members. Then the outside rails were firmly mounted to the drive train frame and cross-braced at the top. It required exact spacing at the top and bottom to be smooth, and I will conjecture that the force that pushed/pulled it up had to be almost dead center as well. If you got to see their model up close, it was smooth as butter and very lightweight.
