I did the first frames yesterday. Only required about 18" cutting each
side. It was an education in how tough a simple polyester laminate can be.
I cut the top and bottom of the frame and used a Dremel tool (with a right
angle attachment) to cut the tabbing on one side. Didn't cut into the
plywood because the cutting disc is too small.

I hit the piece of wood framing with a 2 lb hammer. Bounced off. Hit it
repeatedly and it bounced off. I then cut the tabbing on the other side and
had to literally pry the ply frame off in chunks with a prying tool and a
chisel.

I had a strip of raised tabbing each side of a putty fillet that I ground
down with an angle grinder and 24 grit disc. It was an o.k. job until the
angle grinder got going and threw dust everywhere as usual. I hate angle
grinders for this reason.

I am wondering if heat will work. The guy who hosts the DuckWorks site
wrote about cleaning up cured epoxy squeeze out on a lapstrake canoe by
heating it with a "heat gun" (some sort of hair drier?) and scraping off
the softened resin. With the resin softened maybe the glass tabbing could
be cut with a utility knife. There would be no dust flying about.

You have to be careful when using a heat gun. It tends to delaminate epoxy
and glass from the wood when it softens on top of wood that's getting hot.
I believe the wood is probably outgassing underneath the laminate from the
heat. Use the gun, but sparingly and in small doses.
