Built a couple of mounts for the Airfix Lanc nacelles..
the inside of the nacelle, stuck the tracing to some card and then
sanded to the traced pattern. Stuck that to more sheet, and traced the
outside of the nacelle, and sanded to shape.
Had to sand the front of the Hampden engine mounts/nacelles flat, then attached the mounts to them.
Now the transition to the Lanc nacelle can be filled and shaped, without having the nacelle in the way.
Plenty of Fill'n Sand ahead.
