Hi some comments on this very commonly made ring
Metal would have been better if 1.5 mm, it would be stronger for a
man 2 mm would be good.
Too much metal wasted, not need to cut off so much metal
Too many solders
Ring not evenly round, knot should have been hammered, to make back
of knot smooth. Also if this was done there would have been no need to
solder knot together as the metal on back of knot would have "bitten
into" itself on the back of the ring and so not slide apart. Also
inside of ring would have been smooth.
Back of bands not soldered together, so will come apart with wear
over the years. A quick google of this ring shows the two bands
soldered together and many are fully round.
This is a ring that has been made for decades if not centuries. It
can be made with fewer steps and made round.
Still the video shows a process that can be improved, but
instructive in its own way.
Just some observations
all the best
