"Gerald Ross" (clip) I have seen the guide rail loosen on the tube, the two
tube sections loosen from each other, and the tailstock loosen on the guide
rail.

The Harbor Freight version makes up the rail out of two sections, pressed
together. Mine have also loosened--I think this is a very poor design,
probably done to make the shipping easier. The Sears version, as well as
the Ridgid, sold at Home Depot, both have a one-piece monotube.
