Then put the skins in place and match drill from the inside. You can use pieces of plywood cut from the shipping crates to makes stiffeners for the tail cone bulkheads to keep them straight while drilling. Use a hole saw to add holes around the perimeter for clamps. Using this process assures that you will never come up short on edge distance.

its been a long time, but I think this is how we did it. back drilling works nice.
a few tools that I was going to suggest that you may not have that you will either need or at least find valuable. Spring loaded center punch, fan spacing tool, and 90 degree angle drill.
Another good idea is to put a piece of 3/4" particle board as a table top for at least one work bench. then drill thru the part you are working with and into the wood and cleco to hold the part.
