We’ve done the CAD design, CAM-toolpaths, and CNC-machining for a set of RG65 model yacht (looks roughly like this) fin and rudder moulds. They will be shipped to the customer on Monday.
From time to time I get enquiries about making moulds like this, for fins, rudders, bulbs, etc., from people around the world. Usually by people who’ve gone to a professional mould-shop or cnc-workshop with their drawings, and suffered a bit of sticker-shock when they’ve seen the quote. For this set of moulds we asked 500 euros, which is not a lot I claim. Production and delivery in one week or less after the final CAD-drawings were available.
If you’re interested in CNC-cut moulds in aluminium or steel, please send your ideas, preferably a CAD drawing, and I’ll send you a rough quote. Keep in mind that our machine has a working XY envelope of ca 500×200 mm, so no single parts can be bigger than this. There are lots of examples of what we do in this blog, you might like: bumper mould (2010 Jan), Rudder mould (2009 Dec), IOM MDF plug (2009 Feb), Microscope part (2009 Sep), IOM Fin moulds (2008 Jun), Telescope rings (2008 May).
