Looks like that thread is where all your info is ?

I dont think balsa and popsicle sticks are going to get you far with this - but you're probably saying that in jest ? Why not start with a simple fixed infinity focus camera first, maybe even a pin hole with a 4x5 back or something - it'll get you going, do you have access to any workshop ? I picked up sooooo many ideas from watching other people work, tools that looked like a mystery in the shop all of a sudden have purpose very particular to my needs...

Years later and here I am with a auto tool changing 4 axis CNC VMC - yes, you'll need one of those soon too
