Mark Hasting has done an excellent job of machining a plug to make a mould for my F85 rudder.
Hand shaping doesn't hold a candle to the accuracy of his CNC machine.
I'm in the process of putting a finish on the plug.
After spraying with two pack the foil section has been cut back.
Once I've done the same to the back board I'll start waxing it to make sure we get a good release.
