I dont have my stuff with me right now, ill try to explain it the best possible. First tie a slider with desired length of line(we like 10-12ft)of line , one end tie a snap and swivel( part the bait goes on). On the other end tie just a barrel swivel. Then take the tubing about 1.5 inch long, half way up the tubing cut the tubing half way through, just a slit in the tubing. To assemble take the line from your rod put it through the tubing to where you slit the in the tubing, pop the main line out the slip in the tubing, string the main line through the swivel( not the snap and swivel) After the line is through the swivel, put the main line through the rest of the tubing. The swivel should sit right in the slit you made. The tubing may not want slide sometimes, may have to wet it sometimes.
