Borrow a tile saw?
 

Don't suppose anyone has a tile saw laying around from a tiling project that they might be willing to part with for the weekend?

Yes, princess auto for 50, 60 at rona, or rent em for the same; but I'm scottish...

(Yes aquarium related - learned 3 years without practice = becoming useless with a glass cutter (luckily it's that same diamond blade for tile & glass))

PM's are good,
