I already know this was an ill-conceived project, but I am too far into it
to abandon it.
I found a pile of pretty nice 2x6 PT abandoned in the street. I planed
them, routed a glue joint edge, and glued them together. My plan was to
then paint them with truck bed liner (polyurethane) paint, put some foam
floatation under them, and use them as a dive platform. The glue seems to
be strong enough, but they flex pretty bad (whole thing is about 4' x 6') so
i also threw in a bunch of pocket screws. Didn't help much; so I am
thinking about painting it, and then putting on two aluminum angle irons.
If I screw the center down securely, and use slots up to 1/2" long at the
ends, will that accomodate the expansion? The angle irons will make it
easier to attach the foam, so maybe I can justify it that way.
Any other ideas, other than throwing the whole thing out and using plywood
like I planned before finding the PT?
Thanks. I hope you could make some sense out of my jibberish.
BTW, I glued up some boards and anchored them in the lake last October; just
to see if the glue would hold together. They seem no worse for wear; though
they aren't floating very high!
