The Tale of Tails
Like a good pack rat I've collected my share of tail templates. And being a bit fastidious I keep them sorted by shape. Squash tails to the right, round pins in the middle, and random curves to the left. The center, top, round pin template is one I made over 25 years ago and it still gets play on a regular basis. The nifty hieroglyphic marks on the templates are how I keep track of what curves I use on each customer's board.
