how much you pay for the blade >? you can get the genuine eco fan blade for 15 quid ….
the parts for eco fans are SERIOUSLY cheap…..
i bought a motor direct for 10 quid , the blades are 15 and you can get a thermocouple from ebay for about 15 quid also(they wont sell you a genuine one) its the heat sink and cooling fin bodys that are expensive
im tempted to build my self a second as you hgave done stoner – with a three blade fan.
the stirling engine one is right up my street(v8 stirling engine !) shame you have to start them by hand 🙁
gratutitous stove shot.
i trust you have seen this ? with and without fan
