Steel Fin Moulds

Administrator — Mon, 22 Feb 2010 06:33:34 +0000

Jari machined these steel fin moulds for the PIKANTO over the weekend. The fin will be moulded with a clear glecoat, one 200g carbon layer as a surface layer, and one 250g/m2 UHM UD carbon layer. We are going to use either cnc-machined balsa cores, or a 2-component epoxy foam core. The bulb attaches with an M3 threaded rod which will be moulded into the lower end of the fin. At the boat end we’ll insert a metal piece with M4 threads so the fin can be attached to the boat with an M4 hex screw.

Jari shot some videos during the milling of the beaver-tail bulb. They now appear on YouTube.

For a mostly home-built cnc minimill of this size, this is pretty ‘hard core’ stuff…

Steel bulb nr3

Jari made this steel bulb over the weekend. It has a slightly triangular cross section in the beginning which flattens out to a ‘beaver-tail’ at the end.
