"Doming" the fret ends, a better way...

I always file a dome on the ends of my frets before installation. Gives them a nice look and also lets you fingers slide over them easy.

This time I came up with a better way to do it, rather than hand filing that tiny end.

I chucked a grinding wheel in my dremel, installed it in the router base, and clamped it upside down. This let's me hold the fret and grind it on the wheel while it's spinning. This was much faster than doing it by hand with the file. You can also slow down the dremel for better control.
