Bradley,
Keep your design as simple as possible for your first camera. On my camera I just 
loosen 4 thumbscrews and remove the back and rotate it 90 degree's and put it back on. 
This is working very well and have not had a problem with it. My 8x10 has a tapered 
bellows to help limit the weight of the bellows and help prevent sag when extended for 
close up work. Your camera design can be tailored for the type of work you
intend to do.

I might suggest Ansell Adams book "The Camera" as a study guide so that you can get 
the basic concepts of camera movements and  what they do for you. Moving the back of 
the camera (tilts and shifts) rather than the front causes less vignetting problems 
for example. I found this book extremely helpful in designing my camera since I 
totally understood what a view camera was.
