When I first bought a dozen cheap bobbins
for the classes I lead I noted a common
problem of jerky drag on many spools. When
I looked closely, I noticed that the brass
pieces that fit into the spool were conical
and not spherical in shape. My analysis is
that with a spherical pivot, even a spool
with imperfection will at least rotate
uniformly. A conical tip on the bobbin
however, will bear on the hole in the spool
only at two points unless they are in perfect
alignment. In this situation, anything less
than a perfectly round in the spool will cause
a variation in drag. ~ Ray Kunz
