My friend Matt shared a great link, called the Geurrilla guide to CNC machining, mold making and resin casting.  I’m mostly up to speed on the CNC topics it covers, but I find the mold making and resin casting parts to be pretty exciting.  I have long figured that I am well positioned to try that out since I have a CNC milling machine, so perhaps that will happen in the near future.  I’m still trying to think of a project that would be a natural fit for resin cast parts, though…
