We looked into some tf apprenticeships, but couldn't swing it for time/money and other logistical reasons (travel,etc). To me wood joinery is obviously the purest coolest thing. However, other than the logistical problems, our wood is home harvested and not very big. We want to keep as much of the wood as possible for structural reasons. eg: using round posts instead of square and using metal fasteners. Plus we have several metal working friends just down the road who do beautiful and artistic metal smithing and other types of metal work, much of it using salvaged metal from the local abandoned RR's etc..
