I am going to trim some plywood frames that intersect the hull right at the
shoulder position of a few quarterberths. These are either 1/4" or 3/8"
plywood frames, tabbed both sides to the hull. By the way, I'm a naval
architect and mech. engineer so I have a pretty good idea of what I can and
cannot cut

I can cut down into the glass with a jigsaw, but the baseplate of the jigsaw
will bump the hull before I get close enough - and I would like to run the
cut line right down the hull for about 12".

So the tools I have available a

- angle grinder with cut-off wheel
- dremel tool with fiberglass cutting discs
- jigsaw

Any other tools that might work for a tight cut against the hull through
fiberglass tabbing? The only other one I can think of is a reciprocating
saw ("Sawz-All") but they are a bit hard to control and still get a nice
close to the hull.

I recognize I'll have to do some grinding / sanding of the last of the
tabbing but would like to minimize the amount of this.

Never tried it, but how about a Fein Multimaster with a cranked saw blade?

japanese saw.

That'll do it. Get the HSS blades.

Howsabout a good old-fashioned coping saw for the primary cuts, followed by the
grinder?

Steve

a series of holes drilled with a 90 deg attachment?
do they sell flexible extensions for rotary drills?

Evan,

You really should invest a couple hundred bucks in a Fein Multitool and
an offset carbon steel blade. It will cut glass right up flush with the
hull and sands better than any of the other tools I have. It is by far
my favorite power hand tool.

sanders.

If'n I were doing it I'd use the grinder after the jigsaw & spend the
extra time to make a plastic & duct tape enclosure with a shop vac
hookup to keep the itchy stuff & dust from migrating. The grinder will
be sloppy but you'll need to clean up anyway so why not just contain
it at the start?
And you won't have to bother your kids later to try the bunks out to
see if you have gotten all the glass fibers cleaned up.
