Rack Discussion Continued - Slide lubricant

[Chuck Guzis]

Hitchhiking on Mike's thread, There's a question that I've wondered
about regarding rack slides.

Right now, for a couple of tape drives, I'm using slides rated at 150
lbs., yet they seem pretty flimsy when compared the the old heavy-duty
slides we used to use.

Has anyone tried using the standard heavy duty (e.g. 250 lb,) extension
drawer slides for their rack work?  Post-to-post, my rack is 26" deep,
if that helps.
