Like a carpenter making chairs 

To become bored of a hobby or pastime once enjoyed, particularly because of it becoming part of a job or daily routine.

You spend enough time putting the hammer to people, you start to feel like a carpenter making chairs. Drains the fun right out of it.

like hell you are 

Response to an unfathomable action statement made by another person. The respondent simply and sternly explains this will not take place. Ex: son is not allowed somewhere, but tells his parents, "I'm going anyways!" The parents may respond with, "like hell you are!" Respondent may feel the person had a lot of 'nerve' to say such a thing.

Lover tells their partner during an anniversary they are going to a club instead of spending it with them. Their partner would respond "like hell you are!" Meaning you aren't going, period.
