Scott, Iggy, may be out selling somewhere this weekend or he might just be enjoying some family time this holiday weekend. We will tag him though @Iguanadon so he can come in when he returns to the village and give some more info./insight on his processes. He has done several threads here in the Village that outline how he does his puzzles from setup, cutting, to finishing as well as one on his selling setup. If I don't find them quickly to add the links to here, perhaps he can when he returns.
Oh, looks like he has been at the Farmer's Market this weekend - see this post in Bragging Rights

You can find his website, with all of the different puzzles he has that were created by Harvey Bylar for purchase here:

and here is link to his original post on his "assembly line" setup on doing his puzzles. http://www.scrollsawvillage.com/forums/topic/20547-iggys-animal-puzzle-assembly-line/
You can search the village for more of his threads or wait for him to come along and give some more links.
