I'm in search of ideas on this one. I'm looking to build a unit that sits on my electronics workbench that will hold a keyboard, mouse and monitor. I want the unit to easily slide off to the side of my bench for when I'm not actively using the PC. Here's a rough sketch of the idea.
I had originally planned to use a set of ball bearing rollers like the type pictured below. I quickly realized, however, that they focus the weight down to a small area creating enough pressure to dent the soft plywood surface on my bench.
My next, and current idea is to use a set of plastic "furniture slides" like one might nail onto the bottom of chair legs. I'm sure that this will not glide across a table top as smoothly as I would like though.
I cannot got with swivel casters (which would be ideal) as they are simply to tall - I need to to be lower profile, at least in the front.
Does anyone have any ideas for a slide, caster, etc. that would work well for a tabletop application such as this?
