I had my father’s truck fixed a few months back because of an oil leak. Upon inspection it was found out that an oil seal was worn and causing the oil to leak from the vacuum pump part of the alternator. While the mechanic was working on that I suddenly had the idea of using the vacuum pump of the alternator to degass resin and the silicon rubber for casting after seeing how powerful the suction was.

Update: Regult HDP is available at HobbyLink Japan for 38000 yen.
Announced this month was the release of the limited run Regult HDP Kit by Yamato Toys available at their website. And it doesn’t come cheap at 39,900 yen. The unit is made out of Heavy Duty Polyurethane.
Comments Off Update:: Found out that this available at HLJ, but you have to contact them directly by email because of the price.
More updated shots of the 1/2000 Macross SDF-1 Prototype resin kit by Yamato Toys. Price for the kit is still an eye opening 210,000 yen. Based from my understanding of the literature, they will only be able to produce 10 kits per month of this behemoth.
If you find the price too steep, you can always try building your own Macross SDF1 using everyday materials found in your hardware store.

While studying resin casting I was told that no release agent will be needed when making Silicone Rubber molds. Release agents are used to create a thin layer between mold and master(usually fluid) so that it will make it easier to remove the master from the mold once it has hardened.
Most of the time however I’ve noticed that with tight or small spaces of the master, the Silicone Rubber has a tendency to stick to it. It could be a case of just incorrect mixing with the hardener and Silicone Rubber, but the best way to ensure this from not happening is to use a release agent.
