Jari cnc-milled rudder moulds for the Pikanto IOM this weekend. The design is similar to the Sails ETC rudder, but slightly larger and with a NACA 0006 airfoil profile, and a slot for a 4mm rudder stock.
When not shopping online for lathe-electronics/parts I have been busy sanding the Pikanto moulds. First the last bits of 180-grit today, then all over with 240 grit, and finally started with 400 grit which I will have to continue with next in the next session. The flat bits and large gently curved areas of the hull are easy and quick to work with but as always the devil is in the details. The deck mould has a lot of edges and features that are tricky to sand, and all moulds have a sharp 90-degree edge which is easily damaged when handling the moulds.
The plan is to go 600-800-1200 grit next weekend and do a bit of polishing after that.
Our three-piece hull/deck-moulds for the Pikanto IOM (designed by Graham Bantock) are now ready. The next step is to sand the surface smooth and polish the moulds. We hope to mould a prototype hull before the new year.
And here some pocketing in aluminium:
The parts of the plug have been glued together, painted, and sanded. We should be ready to lay up the moulds in a few weeks.
The final MDF piece for the plug was milled today.
The first half of our Pikanto plug is now milled. The other half will be done next weekend - and then we have a lot of painting and sanding to do before laminating moulds.
Jari is making plugs for our latest IOM-project, and he posted two new videos:
The 1000 mm long hull plug will be made from a left and a right half, and each half consists of three parts. This is the first part from the bow to around 300mm.
