bamboo cane pole ferrule help

[fish_4_any]

I want to make some bamboo cane poles. I have been looking and researching trying to determine the ferrules I need for the sections and I can't figure it out. I have tried contacting mud hole and 2 other places to avail so I figured I'd ask the experts.



That is the top end (left) and bottom end of 2 sections for one pole. The diameter is 3/4 inch. I know I will need to sand down the end with the node, which is the bottom, to make the ferrule fit. I think once y'all help me with this first one I can figure the others out pretty easy. The numerous videos I have watched didn't cover what I needed to help me understand what size ferrule to get.

I did find that the way I cut them is supposed to be correct but if it isn't please let me know. I want to still make this one because I have them and they are dry and want to use it next spring.
