Speed bumps..Shots...Beads...ect. They can be useful to help keep a
ring from turning. Usually positioned @ 5&7 o'clock.
For the most part I don't find them useful for arthritic hands
because the knuckle is usually much larger than the finger. Since the
ring must be able to fit over the knuckle with the "Shots" in there.
That means the ring must be larger still to accomodate the room the
shots take up.
Another consideration is that you will contaminate the platinum if
you solder in the shots. I did notice one post that mentions fusing
plat beads...a difficult job inside a 3mm band that has stones. I
would suggest soldering in platinum beads with either 900Plat plumb
solder from PMWest or use as little as possible of white gold solder.
The cautions are consideration for future sizing needs...Should you
need to weld the ring in the future. A tiny amount of white gold
solder could be easily ground out. I do not suggest counter sinking
the beads in any material since many customers want the shots removed
down the road and/or the same considerations for future resizings
