Did you have yours machined or was it manual?

This frame was machined at a local sponsor's shop by me. The grunt of machining holes in rails was done on a 2 Axis CNC (Prototrak) converted Bridgeport, with the CNC positioning I was able to bust the rails from 5-10 minutes each, the machine was big enough to do any rail in one path and also had an power draw-bar for super fast tool changes.

The debate on whatever doing a hole pattern in every rail is worth it or not is one that my team is still kinda spilt on. A lot of people have told me that I could have "saved a lot of time" if i just drilled the holes I "needed". I however believe that having a standardized bolt pattern to be a life saver and make general construction a breeze. And allows for fast changes to the design, plus doing them on the mill makes sure they are all square and dead on, and with our machine abilities it wasn't that much time.
