All of these posts from David in this thread should be stickied on the CPC vendor page in a FAQ thread. Good stuff here.
Regarding edge spots, is the reason a 3D316 spot (i.e. Lakeshore $1, $5, $20 edge spot pattern) is not possible due to the quick changes in temperature in the slug or more to do with not being able to make a suitable press that wouldn't break? An introduction of this spot to the CPC repertoire would see me remaking a few denominations of my customs.
