There are a couple of threads on the jig tying forum over the last 3 or 4 months that talk of this. They spurred off a thread about making 1/24 oz. mold. I think It was said two 1/32 oz Would run about the same as a 1/24. I am not cleaver enough to post the link or i would. The running speed was .7 mph I believe. The info in those threads will be of more help than I am. Good luck.
