The third production PIKANTO hull is red.
Elastosil M4503 Bumper
Elastosil M4503 is a condensation-curing soft white silicone I am now using for the PIKANTO bow bumpers. The RTV-615 I used earlier was an addition-curing silicone and cured in 60 minutes at +100C. This one will not cure faster at an elevated temperature. The datasheet suggests 24 h at room temperature, but I found 48 h was needed.

Translucent Two
The second PIKANTO production hull was taken out of the mould today. It's made with a clear gelcoat and will be painted later.
I've created a PIKANTO-Page which will have details about the project and future sales.

Wires, wires, wires…
Number of wires from servo-motor to controller on my lathe build: 19.
1: Motor power U
2: Motor power V
3: Motor power W
4: Hall sensor +5V
5: Hall sensor U
6: Hall sensor V
7: Hall sensor W
8: Hall sensor GND
9: Encoder +5V
10: Encoder A
11: Encoder B
12: Encoder Z
13: Encoder GND
14: +Limit switch Common
15: +Limit switch N.O.
16: +Limit switch N.C.
17: -Limit/Home switch Common
18: -Limit/Home switch N.O.
19: -Limit/Home switch N.C.
The motor currents go through the AMP-connecor, everything else through the 25-pin D-connector.
I'm glad the lathe only has two servos (and a spindle), I would go mad with a 5-axis machine...

RG65 Fin and Rudder moulds
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 500x200 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).
