Enough of the thinking, time for some doing!   My son came good at Christmas with a copy of the Brian Lavery/Geoff Hunt book "The Frigate Surprise", number 165 of the limited edition of 250 which includes the signed Geoff Hunt print, marvellous.   I have purchased a Scheppach Deco Flex scroll saw to cut out all those curvey bits.   The book includes lots of line drawings including the all important hull profiles which I will scan and enlarge to the right scale then
