Lake hatch work - click on pictures for a larger view

Here I'm working on the lake that will also serve as an access hatch. I used 1/2" plywood and attached it to the existing 1/2" plywood trestle base. I leveled the trim ring and mounted it using risers screwed & glued to the ring and screwed to the bench work.


Two pieces of 1/2" foamboard were glued together with the layers offset so that a lip hangs down even with the bottom of the 1/2" plywood. I contoured the foam using a rasp and sanding block - it's attached to the plywood with foam-safe caulking. The foam ring will serve two purposes: 1.) It will serve as a mounting point to glue the cardboard webbing, and 2.) It will "seal" against the lake surface. I'm using 1/8" hardboard for the lake which will be painted both sides. The hardboard will have plywood bracing underneath to make it strong. The top will be painted "lake color" and be covered with Enviro-Tech Lite(TM).

I've started the cardboard webbing work here and will continue it as far as I can. I say that as I can't complete it until the trestle is permanently affixed, and that can't happen until I rework the trestle (see previous post).
