Jim,
The Baron is a great kit. To me, it's easier to turn than a slimline! Even if you simply turn it "bushing to bushing" ("b-to-b"), the pen looks really sharp when it's assembled. I'd suggest doing your first as a b-to-b so you see what the pen looks like, then playing with alternative shapes. I can't remember whether it's the Jr. Gent or the Baron that has the slightly different sized components (e.g., on the cap, the finial and the trim ring aren't the same size); if it is the Baron, just make sure use the correct bushing on the correct end of the barrel, otherwise your wood may not be oriented properly (at least you've always got a 25% chance of getting it right by accident anyway!). Make sure that there isn't any glue in your tubes when you go to assemble, either - that can be a BIG problem (not that I've had any crack during assembly or anything...[:I]).
Good luck, and we look forward to your pictures!
