These parts seemed a bit harder to machine that previous 316 stainless prints.

The flywheel needed light 0.005″ depth of cut with a CCGT 060202, I still got some fine chatter marks while holding by the inside of the rim. Th esecond side was done in softjaws and that did not have the chatter so I flipped it back over and skimmed the first side. Speed was quite slow at around 300rpm again to stop chatter but the rim is quite  athin section so that may have been part of the reason. Boring went OK with the same inserts.

Milling was not a problem with carbide, for what little there was to do I used a 6mm 4-flute from Xuhan via Aliexpress.

Drilling was quite hard but doable with Dormer A022 split points

All three of these I used a drop of neat cutting fluid

Tapping M3 and M2.5 needed quite a bit of force using YG-1 spiral flute taps, I’d possibly go up a bit on tapping drill sizes. CT-90 tapping fluid used.
