  Hello Andrew,
  It is possible to buy individual balls for a bearing from some
  engineering shops.
  (I don't know whether you can buy them in vy small sizes ... only that
  you can get some sizes ...)

  With the right grease on a screwdriver (or skewer/match) you may be
  able to stuff balls into the bearing space.
  I've never done this - only thought about my tactic were I in your
  situation.
  I think Ken "G" may know something about this.
