Reaming the holes for the camshaft bearings is almost impossible without something like this. There's a slot down the length of the shaft to hold the sandpaper. I used 240 grit and got a perfect fit in just a few minutes.

Notes:
Use a wide brim so the thing doesn't fall over. I did 20mm and it was fine. There's also a hole in the top to screw an M3 x 30mm bolt to strengthen the hex shaft that goes into the drill.
