We've had access to a waterjet for a while, and we use it for a lot of things. One thing I've always been wary about is bearing holes though. We usually will cut out almost the entire part and then go back to correct the bearing holes with a secondary process.

We might experiment with knurling in house before build, but we have about a dozen other parts that are on the priority list first. Our sponsor can knurl if we absolutely needed it too.

The bearings are more of a tight slip fit then a true press. I can get a good measure on the bore when I go to the shop tonight. We have originally intended to ream the holes under the assumption that they'd run under, but they came out of the waterjet just right it seems.

Got one of the finished Sprockets:
