Mounting instruments into cabin: screws, and boatlife or epoxy?
So, I'm mounting a speaker into the cockpit. The hole goes right through the core, into the cabin. I'm planning on epoxying the interior of the hole, but what about the screw holes (outside the 5" hole, there are 4 mounting screws).
Is BoatLife enough? I've read at WestSystem.com about this process of drilling large holes, like 3/8", filling with epoxy, redrilling with pilot hole, but that seems over the top to me. Practically speaking, isn't boatlife going to do a pretty darn good job?
What kind of screws does one use for glass/ wood combos?
Finally, if the epoxy method is critical...do I use plain, or mixed with the silica? Do I let it harden, and then drill into it?
WestSystem suggests placing the screw in while the epoxy is wet, but that seems difficult, as it will have no holding power until dry. And can you screw it further in, or is it too late?
