Re: Flat surface creation revisted

It seems that a low cost, easy homebrew table would be cement.
good'ol concrete.

one would take their linear rails, match up the mounting plates that
will be embeded in the table, make some sort of alignment jig, make a
nice flat, level pad and just pour away. what one would wind up with
is a massive table top and the rail supports. Then Les's final
scraping tecnique would be easy and one would be all set.

Of course, turing the table over would be pretty tricky. as would
legs.

but with some planning, the table could have a vacuum system could
have the holes placed or uni-strut rails for table bolting runners,
or just all thread couplings for specific point connections.

A simple final epoxy flooing leveling compound would make the table
top flat and can be leveled by the gantry itself.

I'm sure there are reasons why this would and would not work, but I
have seen kitchen counter tops made in this fashion, so for some
parts, it is possible.
