folks, take a long look a zrdc's reply. i bought two 6 ml syringes at wally world today and did almost the same thing he did. only difference i started with two drill sizes below 1/8th and worked up to the 1/8th. they work like a champ. why spent 26 bucks or so when you can get these for 26 cents each and make your own that work, from what i see, a lot better than the bait pump. you can push those nibblets in the end of these with very little effort and push them out the other end with no effort at all. with less effort.
