The nose cone plug is now finished and tomorrow I will take a mold from that
What an experience it was
(elbow grease) and very fulfilling by achieving a pleasing result from the challenge and gives meaning to the saying "necessity is the mother of invention".
Would I do it again? No, period. Would rather buy a Locost nose cone, cut it in four pieces and make it fit and live with the less than perfect shape and curve resulting from such surgery....
Here are some pics of the finished plug.
