we deftly could do a YouTube on making tubes without no problem it would be hard for me to do a video on open water the only thing that I would have would be a iPad and it would be very hard to hold the iPad in fish at the same time I will take it under deep consideration about making a video on making tubes they are fairly simple to make the industry . the big boys use rods for finishing nails or nails they put the rods or nails on boards and dip the nails and hot plastic . I use two different methods we do use nails also an injection molds to make them.
the amazing things about using tubes I have caught every warm water fish on them bluegills crappie bass both largemouth and smallmouth perch catfish squall finish the course anything else that swims in freshwater.
to add to this I have done the same with hand-tied jigs for many years over 55 years I have been using jigs.
