Someone mentioned this subject in another area of the board. I hope I'm not stepping on any toes.
Here’s how I make dink floats. There are, of course, many other ways. First, the ingredients:
¾ in backer rod
“mini” air line tubing (local pet store or hospital oxygen tubing)
super glue
nail polish
flour. orange spray paint
Tools:
scissors
sand paper
a paper tube
a crochet needle (diameter of needle just a bit larger than the ID of the tubing)
The backer rod I got from www.loghomestore.com (same as
www.aloghomestore.com) 50ft of ¾ in gray rod and 10ft of 3/8 in white rod for rags, including shipping $12 bucks. I have enough rod to last me the rest of my life.

I make most of my dinks about three inches long. I trim a taper on one end of the dink with scissors. Maybe an inch long. I smooth it out with sand paper.

I cut a piece of tubing about half an inch longer than the dink.

I push the crochet needle through the center on the dink, top to bottom. Slide the tubing onto the needle snuggly. Pull the needle back through the dink, twisting as it goes. When the tubing is about half way though the dink, I put several drops of super glue between the outside of the tubing and the whole in the dink that the tubing is sliding through. Then pull the tubing the rest of the way through the dink.
When the super glue has dried, trim the excess tubing and paint.


I’ve not found any paint that will stick to the backer rod well. Even the stuff that is supposed to stick to plastic peels off. However, nail polish sticks to the backer rod and it stays flexible. So I put on a coat of nail polish.

When it dries, I put the dink into the paper tube (just a holder) and spray a couple quick coats of flour. orange Krylon. I estimate the whole thing at a cost of 8 cents and about 10 minutes (not counting paint drying time)


Oh, yea. That flour. orange paint is visible for nearly 100 feet.
