Beautiful work, davmac! That transition from body neck is quite elegant.
What species of wood are you using? The Tele looks to have a (maple?) top. How far back do you mortise the neck?
How do you think the set-neck design affects tone?
Just watched GE Smith's 50 Watt Fuse DVD, he plays a trussless Esquire throughout it, and I could not get enough of it's tone! A good reason for creating replicas of guitars like early pine Esquires or Broadcasters and the like. I think the only way I can get one of these is to make one, or have someone on TDPRI to make one for me.
I definitely would not consider any set-neck design an option over a bolt on, the guitars at Musikraft are more like davmac's posted above. Which are similar to a Jackson Soloist, which I would consider more modern.
