I watched this as soon as it posted on YouTube. Your boy reminded me of King Kong stomping around after the TE. Is that a tire valve screwed into the top of the boiler?
Looks like it is quite well built and runs great.

Haha, he’s normally really good about not touching, I think he just wanted to keep it moving.
That is a Jensen safety valve, the original had a crumbling spring and luckily I found one that fit while the water was still warm
