Well, dang. This is what happens when you put off a project too long, finally decide to do it, go out and look for the materials you bought who knows how long ago, and find out your storage methods were less than ideal! Rats! That plywood was 40 bucks a sheet.
I was determined to not be defeated!
First step: clean off the 'assembly table!'
Then I built some four foot I-beams:
First piece of plywood. Look at that bow! Imagine using that as a bed for setting tile! I'd be divorced in three minutes flat!
Both pieces set up:
Glued and clamped.
Added some weight. And popped it in a few dozen places with 1 1/4 inch nails. "Until the glue dries!"
Took a few pictures of springtime while the glue set up.
Finished. Nice and flat!
This time, at least, I survived the struggle. And so did my marriage...
