The best way to deal with a “slightly” enlarged knuckle is to put
Normally, yes. But this ring is very wide-- about 10mm at its
narrowest point, in the back. I don't think balls will work out in
this case-- will they?
the balls often do still work. They function not by making the ring
significantly smaller, but by making the inside of the shank no
longer a smooth round hole. the balls indent a bit into the skin,
keeping the still-slightly-too-large ring from turning so much on the
Or, you can adapt the idea to a wider shank. Nothing in the idea of
"sizing balls" insists that they must be round balls. Instead of a
ball, lay a piece of half round wire across the inside of the shank,
or two of them, same as the balls. the result will be more like the
speed bumps put into the streets sometimes to slow down traffic. You
can use half round wire, or rectangle wire and then file off the
protruding corners on the inside to achieve about the same thing. Or
come up with some other variation if you like.
Personally, I like the speed bumps better than fully round balls,
which I find to be too harsh feeling for some people. In narrower
shanks, rather than a ball, I put in what amounts to a slightly
larger diameter half ball, so it’s a hemisphere sticking up inside
the shank, not a fully round ball. Catches less, and traps dirt less
too. The height inside the shank remains about the same as you’d get
with a little ball. More metal is added to make it the smoother
hemisphere shape. Makes it more comfortable.
