A couple of months ago, a member of the US Spacemodeling team showed me a 40mm model he bought from a Russian manufacturer. It had an immaculate surface finish indicative of a internally molded process. I recently came by some scrap 1" thick acrylic stock, so I am taking a pass at making my own 40mm airframe molds.
These are two halves of a complete mold machined on a ShopBot type router. They're hot off the presses today, and the next step is to polish the molds with increasingly fine grit sandpaper. First, I need to polish the mold cavity and resin channel, then knock down the extra material around the cavity and polish the parting plane. More info as more work is done! Time for some elbow grease...
