I am usually using a paper/resin type board, and the problem with
these is that although the table is flat, the blade is curved, and the
section of board that is under the blade, as opposed to on the table,
gets bent enough to splinter the edge.
I finish the boards on a belt sanding machine, or a sanding disc.
I tried a bench fretsaw type machine, but it wouldn't hold a perfectly
straight line, and was too slow for my liking !
I have a table saw, but I am a bit wary of cutting small boards as my
fingers end up too close to the blade for comfort.
I have thought of trying a tile cutting machine to cut the boards, the
small DIY type machines with an abrasive wheel and a water bath.. I'm
not sure how it would turn out, maybe the blade would clog, but it's
got to be worth a try... Advantages include... it is hard to cut your
fingers on them.. and there would be no dust, as the water bath
takes care of that.
I have one in the workshop, maybe I'll give it a try!

I adapted an old sewing machine. First thing was to rip out the mechanism from the underarm and replace the plate where the needle and the tractor thingies go with a plate with a guide slot. Then break off a suitable length of hacksaw blade and braze it to a piece of steel rod of the same diameter as the needle, file one side flat so it fits in the holder. The saw needs to be long enough to always stay in the slot. A bit slow but otherwise works pretty well, even with fiber glass boards.
