Anyone try making boards from click-lock flooring??

We have a few light pieces left over - I was thinking of trying it as an experiment (If I can get a piece that is dark). Seems thin, stable, easy to work with ...

It wont (likely) be as nice as a good wood board, but maybe better than other possibilities. (PLus- what else to do with left over piece??)  - Bill

Yes I have done this in the past. I used a roll-up board with some click-lock floor tiles to make a board that can be disassembled for for storage.

I think it's obvious, but here's what I did: First I arranged and assembled enough clicklock boards/tiles to cover a chess board, and ensured that I had a continuous horizontal seam in the middle (between ranks 4 and 5), and a continuous vertical seam (between files D & E).
I permanently glued all the click-lock seams except the two middle ones, so that I had four individible quarters. Then I cut a roll-up chess board into four quarters, and glued it to each of the clicklock tiles. Then trimmed the excess floor tiles. The board breaks down neatly into four quarters for storage, and fits in a box on top of my chess pieces.

One thing I found: Click-lock joints are not intended for repeated use, so they loosened over time. I wonder if there is another product that can handle repeated use.

I was thinking more at cutting 2" squares and gluing down to 1/4" ply to make a board.

Your build does sound interesting as I've also wondered about making breakdown boards for travel
