The hinges and pins are giving me a hard time lining up. The cowling was never that great in alignment from day one. So out came the heat and holy shit it worked like a miracle. The top just sits down in a perfect alignment and the pins just slide into the hinges so nice. The end of the hinge near the fuselage was tight so I heated this area on the top of the wing and now it slides all the way up so nice.
I also ground the top of the hinges at a 45 degree were they meet and this really helps with fit up, a must to do if using the hinges to hold the cowling on.
