To keep the ball chaos to a minimum, I use an electric vibratory
engraving tool and mark each groove on the rim of the race.. The inner
and outer race is given an alignment mark. The ball from each groove is
put into it's own little plastic baggie and given a number matching it's
goove mark. When all is clean, everything goes back as marked. This
process is a PITA for some, but the cherry on the cake for others. Yuh
makes yer choices.
