Hidden spaces...

Well, I cut the 8" diameter circles (more or less) with the semi-circular blade pictured in post #21. I did a 4" circle too, though I may have used the 1" wide straight blade. Just cut kind of at an angle with a corner of the blade and keep moving around the circle. (I don't know how I did it, I just did it.) Tighter radiuses than that, I dunno... maybe a dremel or jigsaw. Maybe I'd go with a little trim plunge router (Home Depot) that I have. They aren't as easy to control as the vibro-tool though.

Obviously, the flange of the deck plates conceal any small imperfections in my cutting technique. If you're not planning to frame your holes with anything, you might achieve a similar finish with something like rubber window molding with a U-shaped profile that would slip over the edge of the opening.

Abrasion...

I have some rotary files, straight and tapered, for my 3/8 drill. They are great for chamfering around odd places to protect my hide when reaching in for stuff.
Rotary rasp, too, straight and ball shaped.

Cheap and useful parts of the tool kit.

I have found rotary stones for the drill to work well on fiberglass and gel coat, they don't chatter or chip like a rotary file can.
