The first of my "Pete Culler" oars is largely finished, apart from a lot of sanding and maybe a little trimming here and there. Very satisfying thing to make. Lots and lots of planing of wood shavings, which has an almost zen like feeling to it. Hard to stop.
The handle was relatively easy to form, as it starts square, then circular. After that it tapers all the way to the tip, which is tricky. The blade has to be judged by eye and touch, it is very hard to measure anything. I couldn't hollow each side of the blade as I don't have a round bottomed plane, but I think it looks quite good without the hollow.
The really tricky part will be making a second oar to match.
