Re: Building a chair out of glue

glue chair = plastic chair (it might not be the exactly right polymer, but its pretty danged close enough) Think about it - take a plastic chair: if made from wood of the same thickness, it would be extremely fragile, but a plastic chair is more than robust enough for some reasonably heavy-handed use.
