Well, it doesn't take bits too small to drill the driver, planet cage and gear ring. I figure the drillium will shave at least 1/4 pound off of it, possibly more. I'd say those three parts are the heaviest of the whole hub, contributing most of the hub's weight.
As for finding drill bits for the small parts, well, you can buy them at any Ace Hardware.
I'm not looking to win any records here. All I wish to find out is just how lightweight the old AW hub can be, if nessesary.
Take care,
