As usual, while doing my cardiovascular workout today I had a brain flash. Suddenly I realized what everyone had been saying and it all made sense. A cross member at the top of the slide is what prevents the rails from pulling apart. I was viewing the CAD drawing and not realizing it was rotated 90°.
Cory, thanks for the pictures. They're a little fuzzy but they confirm what I finally realized.
I'm glad that you mentioned you were using Teflon as a glide surface. In some situations it makes perfect sense, this being one of them. It is also much easier to manufacture a Teflon glide that fits properly then it is to manufacture a bearing mount without access to a decent mill.
