I have Peter Alexander's book and video set, Shumways "Recreating The American Longrifle" as well as two of the House videos. Seems like the more reference material I get the more I want.
When I started carving ducks I bought all the reference material available, even took art classes to get it right. I quit carving when my hobby became more like a job. I have half finished ducks sitting in my shop from 1986 when I quit, totally lost intrest, burned out from filling orders.
I did the same gathering of information when I started making wood longbows and will never turn this hobby into a job like I did with the ducks.
I find gun building fascinating and a further progression of my artistic ability. What is interesting about this site is I will have a question about some aspect of working on my Beck rifle and within a day or two someone will ask the same question and the really knowledgeable folk here will provide a wonderful answer.
