Use a diamond wheel in a small grinder.
The diamond will cut the fiberglass like butter.
Use a grinder to clean the last bit off the wood.

Hi,

Just removed the old engine in Far Cove and started rebuilding the
stringers.
There's much more fibreglass than I expected: about 1/4" all round the
wood. And
from what I've seen, the wood in in pretty good shape: just some localized
rot
around where the lag bolts went it.

So...what's the Best Way to get the fg top off the stringers? I used an
angle-grinder, but there's now fg dust EVERYWHERE. Any hints on keeping
the dust
mamageable? Run a vacuum cleaner while I'm cutting?

Also: I was thinking of just cutting around the sides, and if poly fg
sticks
as poorly as everyone here says, I could just lift the top off, exposing
the
wood underneath. No Way! The top is definitely stuck to the wood. So
what's the
best way to get the top off: cut the sides in, or grind down from the top?
It's
about 1/4" of fg and gelcoat, and the stringers are about 4" wide.
