In addition to what Ashley said, I use a bandsaw to cut mine
and a belt sander after. Previously it was done with a fretsaw,
but GRP board is hell on blades and the small Dremel ones
hardly lasted at all. It's very important to support the cut exit
side of the board with a piece of scrap wood sheet (eg mdf)
or the blade will just lift chunks out of it and make all hairy. If I
could get a bandsaw blade with carbide tips.........

Same with drill bits - HSS has nothing on carbide or cobalt
by a factor of 100s, possibly 1000s

Often considered scoring and snapping or guillotining but
never got around to it. I think that's the preferred method for
board houses, but if you want to do it with a circular blade,
get the finest pitch thinnest carbide one you can
