Got My drill press yesterday so today I started on the holes in the sprockets.

Centering drill.

Pilot drill.

Pilot holes done in all of the sprockets.

 Tungsten carbide tipped hole saw. Much faster then a normal bi-metal hole saw.

40x 16mm holes.

Looking good.

 Lightened 203g. It was 784g. That's a total of 812g lighter for the 4 sprockets.

Tomorrow I will start on the drive sprockets.
I have uploaded a video of the 16mm hole drilling.
