I've got a need to create a large number (potentially hundreds) of square wooden tiles (long story) and I'm hoping someone can give me some advice around the best method/tools to do this please? I'm looking to create a range of sizes; 20cm, 15cm or 10cm square. I was thinking of being able to cut down larger sheets of hardboard or ply to these sizes. I haven't got a colossal budget to buy tools so ideas towards the budget end of things would be really welcomed.
