Go to Post One of the Minbot inspectors at LA asked me how much a switch had to weight before it stopped being a "light" switch and started being a "heavy" switch. - ChrisH [more]

hubs and bores

finding a 5/8'' bore: it's uber easy to drill out the center of a gear, especially a spur gear with a hub. but sprockets have hubs, just mount them in the lathe hub inwards in the chuck and put a drill bit in the tailstock. for drilling out steel i would run it reallly slowly. that's if you can't find cheap sprockets to your desired bore.
BTW, we have steel spur gears and turned off most of the hubs (so we can still have a setscrew) and the weight was almost cut in half. If that helps.
