The excellent book by Warren and Gidmark provides some good tips and offsets to mark out various designs. I choose the 'Sugar Island' design and glue up blanks in Ash, with some mahogany decorative stripes and protective strip glued accross the end grain.
The blanks are marked out from a centre line, measuring out to each offset dimension and then joining up the points with a clean curve.
The next job was to cut out the profile in plan.
I will revert to imperial measurements as that's what provided in the design book. So the blanks were glued up to an even thickness of 1 1/4" (being the maximum thickness of the stocks). As the paddles will only be 3/8" at most there is plenty of waste. I choose to router the worst of this off before hand planing.
There is still plenty to go at with a smoothing plane, block plane and spokeshave. Once I have my 3/8" thickness (9 mm) in the centre and paddle endges which are shaped down to 3/32" ('say' 2.5mm) I move onto the opposite end and start to shape the grip.
The candle on the bench was left over from a wedding reception and keeps the bottom of the planes moving well over the timber!
Most of the shaping on the stock and grip is completed with a sharp spokesave and the Ash works relatively easily.
