I have a 5x8', pretty thick, plywood base resting on the edges three (maybe
four) 2x12 frames. This plywood base has on it a significant load, maybe 200
pounds. I would like to be able to slide the base (and the load) along the
support frames - not far, maybe two feet, do my business, then slide the
whole shebang back into its original position.

I've pondered various methods and the one that seems the least trouble with
the greatest chance of success is some kind of slickery material coating
both the frame edges and the underside of the base.

I'm thinking something similar to the stuff we see hawked for the feet of
refrigerators and heavy furniture. Whether these sliders actually work, I
know not, but assuming they do, what is the material from which they're
made, is it available in strips, and where do you get it?

I'm soliciting other possible solutions, too. I've considered:
* The material-handling ladder-looking things with scores of little wheels
instead of rungs (too expensive)
* Mounting a dozen or more furniture wheels one the frame holding up the
base (too much trouble)
* Attaching a harness to my cat and using a whip (too cruel)

HeyBub-

Years ago I had to develop a simple, cheap & easy way to move medium
weight items ~150 / 200 lbs along a low production rate assembly
line.

We settled on HDPE (high density polyethylene, poor man's teflon)
strips screwed (counter sunk screws) to a lineup of workbenches.

Instead of HDPE on the moving sled we used an "indoor outdoor like"
product glued, wrapped & tacked to the bottom of the sled.

Dan's suggestion of furniture bottoms will work.

We found short nap carpet on HDPE to be acceptable..... the force to
move your object will be measured in 10's of pounds.

We tried HDPE on HDPE but fabrication debris (esp, aluminum drilling
chips) would embed in the HDPE surfaces, the carpet was way more
forgiving.
