For milling wood, I would likely set up the process in a different way to account for how wood molds are historically built. Looking forward to my winter... Let's keep talking.
Never having held a wooden mold all I have for reference is pictures on the net, they appear to be a series of individual molds glued to a substrate. So with that in mind maybe cutting these out as you would plastic then with the mold halves joined rip individual molds on a bandsaw (minimal waste) If done this way molds could be expanded to 10 sticks each using hard wood plywood for the substrate. Am I on track here?
