Stick Mold w/V-Tail Problems

I had the same problems with the Bears model.  I bought the tall mold and the stik fish mold and struggled to get a good shot when trying to inject with or without a tail in the mold.  I had to modify the stik mold by adding an extra horizontal vent hole.  I am not a machinest so the way I did it was by clamping 2 strips of 1/4 thick aluminum stock about 1/16 apart and used a variable speed dremel to run between the stock.  Came out perfect.  You don't need to run the groove deep.  Just enough to have a gap from the surface of the top plate.  Only need to put the vent on one half of the mold.  Worked like a charm.
