Jill helped me put the prop on for the first time - it is so light!
Fortunately Craig Catto did a lot of the hard work on the spinner as he matched it to the prop - which Ididn't ask for so he gave it to me as present! Thanks Craig.
So all I had to do was to make the fill plates.
Made a template and used 0.040" (as per the manual) for the fill plate and the joiner was 0.063" as per the drawing. Used the band saw for most and trimmed the fill plates with snips.
