Won't be long!!!!!! The one grub is extremely easy to mold, just has a flat pointed tail straight off the body. I never fish grubs but I think they call it a stingray grub. A single vent point at the end of the tail and that mold is set. Might do a full 10 cavity on that one right out of the gate.
The other 2 have the classic large, thin tails. Molded one today and planned my venting points carefully. We will see on Friday after the molds are sealed if it pours with the mold closed.
I have added a hole through the mold to help vent points in the tail. Pics of mold to follow (along with the clear, silver and black flake grubs!!!).
