Full scale screen prototyping began this week. To find the perfect fit, we bracketed tooling settings by testing differentials between the actual bit diameter and those specified in our CAM settings. Carolyn and Joe milled 7 tests, with each removing slightly more or less material resulting in looser or tighter connections. This gave us the control to not only find the perfect fit, but to adjust for paints or coatings and other differences. Carolyn designed a tattoo system that’s etched into each part, so we can keep track of prototype versions and make assembly easy.
