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)



Unable to parse your sentences to figure out what you are talking
about. Can you post a link to a picture? Is this a one-time move or a
recurring thing? First thing that comes to mind is a couple stanley
wonderbars and some pieces of pipe. Second thing is four strong guys
and carry it, adding handles if needed. Third thing would be a couple
of the lifting furniture dolleys (like they move loaded desks with)
mounted permanently underneath, with a way to stick the lever in to
raise them as needed. There is not going to be a painless way to do
this, and if there is going to be a recurring need to move the thing,
may as well go through the pain once to do it right.

Frames stationary, base moves in and out of the screen.

It is the boundary where the frame meets the base that needs the
low-friction solution.

Sorry about the prose - everybody understands what I'm saying and that's
what I'm trying to explain. Things are, however, in such a state that I have
to write this with a gun in each hand and a knife in the other. All are
still safe, fortunately, except those who drowned in an adjacent bog, while
the rest of us wonder how many more goddamn otter skins we'll have to
stretch.
