Busdriver wins the prize. Freddie Parr (http://www.cycledesignusa.com/) is kind of the king of frame pinning. I've used various kinds of nails quite a bit, but his pinning kit works better for me. I also note the site is now linking to a frame building course in Arizona. Pricey, but ten days of one-on-one with a top builder is sure to get you a head start...
