Pole Transformer Fabrication
Why people recommend it
Factory footage of a pole-mount distribution transformer being assembled; cited for how the core and the sheet-wound low-voltage winding are built.
Watch for: the sheet-wound low-voltage winding
In their words
For those interested in how pole mount transformers are constructed, here's a video of the assembly process:

You should consider winding the other way, with the metal sheet parallel to the solenoid axis rather than perpendicular to it, like the low-voltage winding on a pole transformer, as shown in this video.
