I made a bottom shoot mold once.. Where i fill the tube, insert the plunger, flip and push..... Thought all the air would push up out of the mold, didnt work... Looking back, it could have been the air trapped between the plunger
Dave R.. I like the new drawing too, as long as the vents in the bottom tail cavity are long and thin enough, the rest should fill..... This is quite the project for your first 2 piece mold!
