Dog Star
Western Thunderer
Centre right ( and just to whet Graham's appetite ) is a completed return crank which just needs a little tidying up.
Please do not upset the natives by offering tantalising glimpses! If the photo shows what you have achieved with the return crank then best "words and music" are a necessary contribution to feed and placate the members (can you hear the chairs scuffing on the lino in the rest room?)
regards, Graham
