[Elecraft] K1 Front Panel Assembly: Potentiometer shaft doesn't fit

[Brian Moran]

I'm in the middle of assembling a K1, and have gotten to the front panel final assembly. 
The Potentiometer (type labeled 1-2-3) that I have has a threaded shaft that is too large of diameter to fit the K1's front panel. What's the best way to enlarge the hole to preserve the nice new paint?Or is there something else that I'm missing?  I have Googled for this, however nothing in the first page of results seems to mention this issue.Thanks,
