From Parts on the Table to “I Built That.”
At first, it’s a collection of pieces. Then the shafts line up. The gears find their places. The shifter starts to make sense.
When the finished model runs, you can follow the motion through the mechanism you assembled. Every adjustment, every discovery, every successful shift becomes part of your build.
That feeling is the whole point.
