We made the first set of Didi Mini Transat in the old way of a series of templates shaped to the designers profiles,this is a half profile shape of hardboard,set to every 200mm or so,it works but slowly,one pair of rudders and a foil takes one person over three days to do the basic shaping.We soon worked into using the CNC machine to profile in 3D,then cut the profiles every 50mm,this then gives us a pre cut shape and is quite easy to machine plane to size,we picked up a few tricks as we went,have a look at the pictures.The paint can be any colour,it shows up at the bottom of the cutter slot as we shape into the foil,it tells us when to stop shaping!
