Or rather it shows the end result More information on the way its done would be very useful.
The slot is put in the axle on the outer edge around 2mm deep using a milling machine but it could be done with a saw it just won’t look as tidy. The wheels are fitted and when the quartering is satisfactory the slot in the axle guides the drill to produce the slot in the wheel hub. Then you push a pin in. This method allows the wheels to be removed easily from the axle if necessary.
