Everybody has beaten me to it but yes you are correct, I didn't make a lip on the pipe, just flattened the ring onto the end. I read Mac said he doesn't bother anymore and I figured he has way more experience than I do so I didn't either.
One thing I did (sorry no video) is use the endgrain of a piece of 3by2 hardwood to flatten the ring. I also held it at a slight angle so as to hammer a taper to make it resemble a "proper" ferrule. I worked around the pipe, probably 2-3 times, small hits rather than trying to get it in one go, I found the result was smoother. After a bit of use the timber edges started rounding, so I just docked it in a dropsaw to square it up again, if that makes sense.
If you get the ring diameter right it holds onto the pipe very tightly, making soldering easier, I used silver solder for strength but after checking out Woodducks video it seems soft solder will also do the trick quite nicely.
