Fan Repair Failure

During the hot hot hot Summer our fan broke.  One of the blades ripped itself free and over time another two just sort of fell off.  The metal ummm thing that was holding the blades on must have just got old and tired.  This is a job for my laser cutter, thought I.

The old metal fallen apart bit and below, my less than elegantly designed replacement bit.

I attached the blades….

Looking good so far

and then attached the whole thing to the fan.

yeah, this is going to be rubbish

It was only at this moment, after several months thought and planning, did I notice that the arm of the metal thing was kind of angled…to kind of angle the blade and make it move air and stuff.  The way mine is set up those blades are just going to efficiently slice through the air and make barely a draught.

Can I be bothered having another go at fixing it or does it just get recycled???
