As always with a new mode of fabrication the process seemed intimidatingly untransparent, but once I sat down and began trying things out it was easier than expected. After a few practice mills, and one scrapped board, I managed to get a job running smoothly.
I was able to attach my iPhone to the milling apparatus loosely enough as to not interfere with or risk damaging any of the mechanics, and was able to capture the milling process in relation to the endmill.
