Gotta post the new TwiggyMac pics as well!
Just wrote up a bit about the fabrication processes in that thread and figured it belongs in here . . . . soooo:

I've been planning to make a vacuum forming buck for doing a ProtoHoaxMacTwiggy™ in clear plexi since the Old Guard day over on 'fritter. However a DVD/CD will be popping in-n-out of the opening. Learning about the stamped aluminum "skin" on the Twiggy drive makes this just too easy! [] ]'>
I've got plans on the board for doing a total of five riffs on different ProtoHoaxMac™ Hacks. Vacuum forming plexi convex CRT faces and concave inner bezels to frame LCDs behind 9" and 12" CRT openings is the next development step in this ongoing project.
Old school pattern making, vacuum forming and plexi fabrication techniques trump CNC & ProtoPrinting processes when it comes to clear ProtoHoaxMac™ production in very small quantities . . . not to mention the monetary hit imposed by taking a high tech approach.
Plaster cast of positive part = female cast for positive blank -> shave down positive blank by the thickness of the plexi being formed ->
vacuum forming sections -> trimming formed blanks -> machining Snow White grooviness -> assembly
Lightly frosting the inside of the blanks, by sandblasting, covers a multitude of sins, like the (manual, not CNC) router table bit's machining marks, BTW. [] ]'>
