At least, hand power tools are ok. You can get a small tile wet saw,
desktop, from places like Harbor Freight.

Yes, metal brake. I have a 30 inch metal brake, the 3 in one setup.
It is quite heavy, I have good success with trimming PC board, some
plastics, sheet metal (as long as not too thick).
However, I don't recommend that particular model to you because of
size and weight. It took a shop crane to put it on its braced table
(now on wheels). You can get a smaller metal shear that will handle 8
or 10 inch wide board stock. Your (perhaps best) bet would be to
pre-cut things to the point where you can use the shear.
Score and snap works for me only when I see (and use, and I mostly
don't) the paper based laminates.
You may wish to try a tile wet saw, although I haven't used one, it
does show promise. The advantage of the shear is that I can cut raw
stock, and also trim the final board. A bit of sanding (minimal!)
with fine sandpaper will smooth the board edges.

>Hacksaw would obviously be the choice of inexpensive and easy but I'll be damned if I can cut a straight line. I always have to go back over with a file to clean the edges. Score and snap took forever. I've seen videos of people using 6 or 8" inch sheet metal brakes but never got any feedback when I sent them PMs regarding blade life.
