Binding of a linear slide

[Joshua Sicz]

We were finally assembling our linear side on Saturday and ran in to some trouble. We are using two 2 x 1 aluminum stock that the slides glide on. We have attached a bar in between the two slides. They move up and down as expected but what is happening is that with the slightest nudge of being off, not equally being pulled on each slide, they bind against the metal and stop gliding.

Thanks,

Here is a picture of a slide and could post more later today if the desciption is not clear.
