To be clear, we don’t have any record in the New Testament about Jesus working with wood, laying stones, or helping his pop out in the shop. The only references we have to Jesus’ vocation are the two times when He’s called a tekton or the son of a tekton (the word often translated “carpenter”).
“Is not this the carpenter (tekton), the son of Mary and brother of James and Joses and Judas and Simon?” (Mark 6:3).
“Is not this the carpenter’s (tekton) son? Is not his mother called Mary?” (Matt 13:55)
Now, tekton could refer to a carpenter or a stonemason, but the word simply refers to “one who works with his hands.” If someone wants to describe a carpenter, the phrase they’d use would be “a tekton of wood;” if a mason, then “a tekton of stone.” The absence of either stone or wood as a modifier indicates that the gospel writers didn’t specify which occupation Jesus and his father were engaged in. Mark 6:3 and Matthew 13:55 simply say that they worked with their hands—they were laborers who performed physically demanding and socially shameful jobs.
And I think this is the point. In highlighting Jesus’ occupation, the point is not that Jesus was a carpenter and not, say, a fisherman or a mason (or a mason and not a carpenter, etc.), but that Jesus was a blue-collar worker and not a white collar worker; a peasant and not a noble; a man of humble origins and was not born into a family of high social standing.
So how did the tradition arise that Jesus was a carpenter?
In the early church, some leaders assumed that Jesus worked with wood. Justin Martyr, for instance, noted that Jesus made various farm instruments out of wood—plows, yokes, and other tools (Dial. 88). In an effort to glorify Jesus’ humble occupation, the Gnostic Infancy Gospel of Thomas has the boy Jesus miraculously extending wood that his father cut too short. In any case, the retelling of Jesus’ vocation as a woodworker became as firm as a 2×4, so that even today this tradition is more or less assumed.
