Following are planning notes and a build-log for Mike Lutz's attempt to copy the processes laid out in the Guerrilla guide to CNC machining, mold making, and resin casting

What got this started

Mid october 2012 the Guerrilla guide to CNC machining, mold making, and resin casting became the top link on ycombinator's Hacker News. Mike stumbled upon it there and posted a note to the LVL1 list about it.

That lead to the discovery that the club had an offline Zenbot_1216_CNC, and through large amount of work (of which, much of the work was done by Chris Pettus), the Zenbot was brought online.

Having gone through the zenbot setup process, and feeling as though that gave him some idea of the depth of "rabbit hole" that the Guerrilla guide was presented, Mike decided to continue to copy the steps in the guide and see how far he can get.

The phases

The Guerrilla guide bounces back-and-forth between four primary skills: Building up a CNC, Designing 3d parts (gears) in CAD software, Milling a high spec model from a CNC, Making a Silicone mold, polyurethane casting from the silicon mold.
