Ever have problems getting those tail color pieces back into the mold to shoot the finish color? Try this....

I keep a dribble of worm oil on the shooting table all the time with a small child's paint brush right there with it. You can see the tip of the brush at the cavity of the thump grub. When I am re-inserting the tail color portions I want, I run the brush with a wee bit of worm oil thru each cavity on each side of the mold before I stick the plastic parts in. Lubing the slots really makes this process a snap. On this mold I generally run the brush thru the slots about every other or third shot and I do not dip it into additional oil until after maybe twenty uses in the mold.
The same procedure helps if you are putting parts back into the mold on the ring-it worms, birch bug, flippin' zip or any other bait that has similar features that can stick or bind.
