Hi John I have always deburred both the rim eyelets and the valve hole. To start out with I did it because that was the way I was taught. At a later date I encountered some wheels where the head had been milled off the nipple. I have come to believe that by deburring the eyelets this is less likely to happen Geoff Duke Melbourne Australia

Have any of you found a need or value in preparing/cleaning/deburring
the rim eyelets on the inside, so the spoke nipples will seat well? How
about deburring and smoothing the valve stem hole? Is there any harm in
reaming the valve stem hole from Presta size to Shraeder size?
Thanks,
