I want to make a large number of wooden cubes and square tiles approx 25mm in size. These are for wooden puzzles, hopefully to be sold at craft fairs so the finish needs to be good and they all need to be of a uniform size. In the case of the tiles, the corners need to be slightly rounded. For the numbers I need, they are too expensive to buy ready made so can anyone give me any tips on producing these? I have a table saw already which I presume will be recommended for this. Thanks.
