The centrifugal fan is almost complete. As the fan runs on 240V AC a lot of care is being taken to make sure the fan does not endanger anyone.
The following photo shows the fan and a plywood former for a length of thin steel that will act as outside of the fan casing.
The next photo shows the rear of the fan with the AC motor. As you can see there are plenty of bolts holding everything together.
All that remains is for the front face and sides of the casing to be completed.
