The SDPI gears are made from 12L14 - can be case hardened (at home even with some kasinite and a torch). It wouldn't be worth trying to ream/bore one of my pinions - they are through hardened and are too hard - it would require a stiff, beefy lathe, an expensive tool and coolant to even make a go at it.
