I didn't know wether to put this here or in the ATM thread.
Stumbled across this interesting and very fascinating site. Jim and Rhoda Morris make (among other things) precise replicas of Galileos scope.
Included on the site is a description, with photos, of the construction methods employed by Galileo. There's also links to other informative sites.
