First the background: I'm building a box to store a bunch of tooling and fixtures for a metal lathe, BUT want to make
provision for future use of it for other things. So! The thought was to make an insert of thin plywood that could be
configured (sort of "egg crate" wise ) to fit the current things and an entirely new one for other things if and when
it occurs. And then completely empty for other uses if/when that occurs.
The "Box" construction went just fine, so started on the (I'll call it a) linner. Used 1/4 plywood and had the technique
of "glue-up" worked out that went fine . I held the bottom flat on a good flat surface while holding the 4 sides
vertical and clamping with pressure etc .
NOW the problem : The bottom piece had a slight warp but I thought by holding it flat while glueing all 4 sides to it
and eachother at the corners it would hold the bottom flat. NOT QUITE.!
See the picture.
I think if the warp had been only in a straight line parallel to a side it MAY have worked but this is a diagonal
direction . So one corner is up about 5/16" with the other three flat. It only takes a bit over 2 pounds to flatten
the corner but I can't think of a way to make it stay there. The small areas were to be small rectanles of various
sizes in the range of about 6 x 6 and 2 x 6 and such but all fitted in to the overall area of about 14 by 16 inches.
I hate to "assume" that adding these internal partitions on the same rectangular grid will do anything to flatten
the base.
So! Any comments / suggestions / ideas ????? Thanks.
