Well I have spent some time trying to solve the bubble problem and seem to have it solved for the most part. Still getting a real small bubble by the eyes. What I did does make it real difficult to shoot with the Twinjector but it works for me. Would like some others to try it and see what results they get. Here is what I did. I tilted the molds at about a 45deg angle. The high point of the bait is the upper fin and let's the air out. I shot about 100 baits while trying this out at many angles. I just made a wood shelf that was tilted. Please others try this and let me know if it works for you. Not that this fixes the mold but it works for me. Used real cool plastic too. If the plastic is to hot it runs out of the sprue causing a void in the nose. Frank.
