The EDM How-To Book
The EDM design in Robert Langlois’s book above is good, we have sold lots of copies and many examples of the design have been built, but I rather think this new design from Ben Fleming is better. Its strength lies in the care Ben takes explaining how to deal with the electronics and electrics, on the assumption that there are likely to be more engineers with minimal electronics experience, rather than the other way round, building this machine - which isn’t to say that the mechanical bits aren’t also top rate. EDMs are very useful machines, and not just from removing broken taps, and making one is an interesting process, which produces something you will end up wondering how you survived before you had it. This is another American book, so the voltages differ from most norms, but Ben assures me the adjustments for higher mains voltages are minor. 168 page
