The Carpenter has a crafting space where you put ghosted images of items, and then storage where the ingredients need to go to actually be put to use. You didn't put the diamonds in the Carpenter's inventory space, did you?
The Carpenter needs Buildcraft-Power and liquid, in your case just water. If the progress bar on the right don't raise then you are missing some ingredients in the carpenders inventory or you don't have enought power. Btw: a Hardened machine needs 5 buckets of water
I finally managed to make it after 4 or 5 redstone engines. I'm going to make some sorta of water pump sytem to keep the carpenter full along with maybe some steam engines.

Redstone engines are gonna be pretty slow, would recommend upgrading (I'm pretty sure Peat works or Electrical if you power them via IC2) plus not every recipe requires water, some needs seed oil etc so pumping water continuously is not necessarily the best way.
