OK! OK! OK!!! I consider myself severely chastised. So I bought 1/32 balsa per your instructions at the LHS. I have taken a couple pics of the nacelle to give you an idea of what is required. The hatch on the front covers the nacelle from the firewall N-1 to N-2 the LG mounting bulkhead. The remainder back to N-3 is to be planked. I want it removable for access to the LG and potentially the installation of retracts. The outside surface of the hatch must match the outside surface of the nacelle.

So how do I do this Bill? I am ready to cut balsa.

Two pics, one gives the overall nacelle, the other gives the detail dim.
