Gentlemen, your input here is super helpful. Some of it confirms what I was thinking, i.e. if they look too fat then they are too fat. Still, getting input from others is valuable. I will try to get a copy of Jerry Fisher's mechanical drawing. I've seen images of it, but I'm not sure I've seen where it can be purchased. Either way, I'll research it. And I just purchased a copy of Dave Westerbrook's book. Thank you all for the help!
