This is the process that I used. First I had to pick a mold and I decided that my 4 inch carrot mold had the circumference for a tube bait that I wanted. Next I had to figure how I was going to get the rods so I decided to use a cut up coat hangar cut to size (the tail on these carrots are so small I knew that I wouldn't be able to close the mold if I made them full size so I chose to cut them to 3 3/4 inch. I liberally greased them and placed them in the mold and injected them. The baits came out perfect. I cut them down to 2 inches and cut the tails and put one on a standard Ned head . when it cools off I will fish them and let you know how they fish. The beauty of this system is I now have 3 choices. 1. Shoot the mold as it was meant to. 2. Insert the rods and make my tubes. 3. Insert the rods, inject the baits and this time just cut off the last quarter inch of the bait, put it back in the mold and shoot your core shot/tail color. Pretty useful alteration.
