That link does help a lot, but I was also hoping for a 'what can my pickaxe mine' guide.
I built an Extractor in my single player game, realized I put it in the wrong place, hit it with a pickaxe, and only got the Machine block back. Took half an hour to find more rubber. But the Generator beside it mined fine, so I dunno.
