Re: [bolger] Laminating Plywood
- Bolger only mentions Epoxy for waterproofing and fiberglass for abrasion
protection. No mention of epoxy for any structural glues. Since the Wyo is
really nailed and bolted together the polyurethane glues should be fine. In
fact the rub rail is 5 inches thick laminated with cedar using 1/4" bolts on
24 inch off setting centers, not glue. Bedded with marine caulking. I can
see this would make for easy removal on repairs. I'll probably lay on a
coat or two of epoxy just in case.
What kind of roofing glue does Buehler mention. Stuff like "Black Jack" tar

- Why nail? just let the two plies float. Realisticaly
we want some load sharing, and if you don't use glue,
your nailing pattern might go from 1' centers to 3"
