Hasluck's Photographic Cameras and Accessories has plans for a whole-plate camera, bellows, etc. There is a free electronic version online but it is also frequently available as a hardcopy on Ebay or here:http://www.youroldtimebookstore.com/product-p/22520.htm

It's fairly simple in its plans and description but worth the price IMO, especially the free one.

As far as bellows, you might have a look at the article listed in my signature.
