1) Thanks to JB for posting, Watty who apparently made the video, and everyone who has added ideas. I am doing my old, original Rev handles today which I rarely use since I prefer my second, longer snag less set. However, nice to have backup and if I ever get my grand kids interested, they can start on the shorts.
2) Shame on Rev for leaving those nasty burrs. One of mine measured 3/32".
3) To get the end cap soff over the above burrs, I closed a small adjustable plastic jawed clamp to just slide over the tube, then used it to apply pushing pressure to the end cap to slide it off. This left a nice mark on the inside of the cap which I guess won't hurt anything, but it's just sloppy work.
