Aug 24, 2009 : Our Own CNC Mill!!! In June 2009, the shop that did our CNC Mill work went out of business. Michael was extremely generous and gave us the CAD data files for all of the design work. We went to a lot of different shops locally and in Denver, but they just charged too much for the work. We found a small shop that has reasonable prices and short turn-around times, so they will be making the airbox pieces for us. Also, they "just happened" to have a used CNC Mill for sale, so we are buying that and setting it up here in the shop. So in the future, we can make our own parts and make changes when necessary.
