Hi,

The outside of the hull has been sealed, filled and has now had four hand painted undercoats that were rubbed down after each coat and it is looking reasonably good.  It still needs probably more coats of paint and rubbing down with some fine wet and dry paper. Alas now in early December in Old South Wales it is cold and damp, not good for spraying the final top coats.  So the hull has been hand painted with a white top coat until the spring when I can sit in the garden with a bowl of warm slightly soapy water, wet and dry paper, and the hull.  Also hopefully the temperature will be more contusive to spray painting in the garage.
Back to a wet December; coupling the engine to the propeller shaft, a helical spring seems to be the usual coupling, but photographs of other types of probably replacement couplings have been seen.  As the propeller shaft came with half of one of these other types of coupling it was decided to make the other half of it.

The couple made consists of a 36 mm disc of 2 mm brass sheet hard soldered onto a 10 mm diameter boss that fits on the engine’s crankshaft. The hole for the drive pin was marked out from the original part of the coupling using a jig.  Hopefully the photographs will show how the coupling was made. The coupling cannot be completed until the new paint on the hull is hard enough to handle probably about a week. After which we will find out if the measurements taken before painting were correct. Until then something else will have to be found to play with.

Take care Tony.
