Well, maybe 'perfect' is a bit extreme. I'd like to make some simple "Soma cube style" puzzles. Many of them are constructed by glueing together smaller cubes into varying configurations.
What I need is to learn how to make small wooden cubes. Clearly, the accuracy of the cuts needn't be microprecision, but that's no excuse for sloppiness.
Can anyone recommend a book or two that details this information? Or perhaps you can just give me a tip or two?
