Question Modern-day Miura: seeking buck making information

If you're not already familiar with my Miura project, the build diary is here: Modern-day Miura

For this project, I'm having a 3D model created for the body design and then having the model sliced into jig/buck stations. I will get the cutting instructions and then have the jig/buck stations water jet cut. I've already engaged professional help with the above but there's a set of answers/information I need to provide to the person doing the modeling work.

Let me state up front, I've done a fair amount of metal shaping but have yet to make a full blown buck. I'm hoping to learn from you all that have experience with buck making so I can avoid rookie mistakes

My initial questions are:
  1. What material (e.g. plywood, MDF, masonite, etc.) that can be water jet cut is best to use for making a buck?
  2. What is the best material thickness for buck stations?
  3. What is best spacing for buck stations?
  4. Should all buck stations be spaced the same or are there areas where buck stations should be closer/farther apart?
  5. What other considerations should I pass along for inclusion in the buck station design/definition?

I have a choice of either making the buck free standing or making it to sit on the chassis. A free standing buck sounds simpler to me but there might be advantages to using the chassis as a buck foundation. Is one of these approaches more advantageous? What are the considerations of going free standing or on chassis?

If freestanding, I've been thinking a multi-piece buck might work best. The Miura body is composed of a one piece flip-up front clip, a one piece flip-up rear clip, and the middle section. Making a separate buck for each of these sections seems logical to me. If done right the three could be joined together to form the whole car body buck. Has anyone made a buck like this? What are potential pitfalls with this approach?
