I just bought one of those ratcheting crimpers and I was having a real be atch of a time trying to figure it out easy peasy now that I've seen it done Thanks for the vidHere's a nice short, but dull video explaining how to crimp open barrel pins.
The only thing I don't like about the crimper I bought is once you have it crimped down you got to apply downward pressure while sticking your little finger in there to open it back up again not a lot of room for a finger
Edit finger in between the handles maybe it's just me I need to practice some more probably
