Nineteen first-person clips, 91 minutes of work. One carpenter builds a full fence gate, hangs it, and tests it. He states the goal in the first minute and closes it on camera in the last clip. Every step narrated in his own words, every clip with a synced 1000 Hz IMU.
“Today we are going to make a fence gate, and then we are going to install it later.”
First he builds a temporary bench on saw horses, because “you don't need to bend... especially at my age.”

“We make a drawing, a very rough drawing, about the gate we're going to build.”
47-7/8" × 81", frame layout, 45° supports. The drawing drives the cut list.

“We cut the piece from the longest to the shortest.”
A wrong long cut becomes the next short piece. A wrong short cut is pure waste. Cross pieces get cut at 24" instead of 30 “so we won't waste too much material.”

“If you're going to build a screw close to the corner, you're going to pre-drill. You need pre-drill. It's important.”

“This side is a little bit low. So it's twisting.”
He shims the corners until it sits true. His drill battery dies mid-job, too. Staged data doesn't have moments like these.

He measures, pre-drills, and drives each one, then does the second face the same way. In between he checks the cut list and the crew group chat on his phone. Real crew coordination, on camera.

“Here it is, now let's try. Perfect, it fit right in there.”
Before the fit he finds a soft spot in the infill and adds a support he never planned.

“Put it tight. Tight enough. Not over tight.”
Bolts, latch, and gap tuning: “if you make it tight, you'll get a hard time to close the door.” Two workers solve a screw-through problem together, in Mandarin. Multi-day continuity on tape: “that's a little bit of what we did yesterday.”

“Last thing, test the gate. Open and shut. No problem. Work is done.”
Then he collects the good screws for reuse. The job the first clip promised is closed.
