This year our team acquired
this CNC router. Although we have had computerized machining capabililties since about 2011 from a mentor's personal CNC Mill, the router was helpful to our team. In your case however you may pursue more digital machining. I recommend CNC wholeheartedly. The ability to customize drivetrain rails and mass produce repetitive parts is incredible and you will not regret it. You will still make parts by hand, but the really precise stuff can be saved for the CNC.
