Looking forward to seeing what you cook up next!

I don't know if I'm sold on an 80/20 or makerslide approach. I'm not sure the parts on offer are the right solution, and cost is a factor. I guess I'm just not sure how it would be an improvement over jck57's current approach.
If we can build it out of wood and standard steel, can't we make DXF drawings for milling both the wood and the steel, for the exact shapes we want?
I just received the parts for my CNC scanner, already painted black by the shop. I just need to pick up the glass (hardware stores here don't carry glass anymore) and I can put it together. The relative ease of sending drawings to a shop suggests to me that good drawings and CNC milling is the way to go.

Couple of questions (out of about a thousand):
How did you find going from the Arduino to the Pololu? Were you able to just use their scripting language, or did you try to
port some of the Arduino code to the Pololu C language SDK? Does the Pololu handle inputs ok? Interrupts?
The reason I ask is I was thinking some input push buttons might be good - a stop and start cycling button, a clear button (for going back a page or two), advance one cycle and hold, etc. Perhaps a pot to control overall speed or camera pause duration. I know, feature creep, I can't help it!
Never used servo savers - can you get them rated by torque value? The ones I've seen don't specify any, so how do you know how much torque is applied before it slips?
I know I've seen them someplace before, but where did you find the acrylic plastic vee parts you use on the end of the pusher arms to clamp the book? Odd as it may sound, I know where to get everything else.
Anyway, Thanks for a great thread!
BTW, I'm scheming up a new version of this that adapts to the Hackerspace scanner. It won't have the pressers with slotted aluminum arms and plastic vees, but will include the other servo gadgets.
