Churning out code all day is all well and good but for a feeling of a job well done nothing can take the place of making something with your own hands. Dave Gingery will show you how to build a foundry to cast parts for a lathe which you can use to make a shaper which you need to build the milling machine etc etc :) Also worth a mention is Ron Reil who knows a thing or two about propane burners for foundries (last link has a very cool pic).
