: Just out of curiousity, being the tool challenged one here, can a router do
: what I was using a rotary hole saw for? Which is cutting a slot
: 1/8"-3/16" wide/deep through wood and epoxy?

I need to cut a slot in my hull 1/2" wide and about 14" long using an awkward router. My thinking was to cut two 1/2" thick plywood strips and glue 1/2" spacers betreen them at each end making a 1/2" slot. Then fasten this slot pattern over the area I want to cut out and plunge a 1/4" router bit through the boat and let part of the smooth bit shank guide against the pattern slot sides. It seems like this would work.
