I'm adding a couple port lights to my sharpie's cuddy. Now, it's an open-back cuddy, so there's no reason they need to seal water-tight, and a $500 set of ports
would be out of place on her anyways. Am working at making my own "Root" or "Wiley" style windows such as this:
They will be 4" x 10" ID ovals, or about 5.5" x 11.5" overall. For an outside frame for the window itself, I picked up both a 3/4" thick slab of oak, and a piece of 1/4" ACX I could laminate triple-thick for 3/4". All would be epoxy-coated and set glued into the cuddy.
Outside of bright finish on the oak, vs paint
over either, is there any significant strength or rot
resistance preference for either wood?
