i think it may still need some fine tuning, i plugged it to an extension cord and it spun with no noise but ill see what adam thinks of it too.

If it's tightened down, all screws in place, and spins freely with no noise, I dont know what fine tuning can be done.

are you saying that it's fixed now? if there is no noise from the bearings or motor, the fan is properly fixed....

Assuming also it runs at full speed and spins freely.

you know what ive noticed, on most fans in general. if you spin a fan that has no blades attached, it doesnt spin as free, but when the blades are attached it seems to glide better. could this be whats happening also? maybe since theres more weight added when the blades are on it spins better...

Weight has a little bit to do with it, but most of all it has to do with the center of gravity, I believe. If you spin around on a chair with your legs extended it will take you longer to slow down than if you have them tucked under your seat; in addition, if you have your legs extended while spinning and then pull them in, you will speed up momentarily.
Finally, you also get a wider range of speeds the more (or heavier) blades you have on it. If you run the fan through its speeds with no blades you'll notice that the motor spins just about the same speed (around 350-400 RPM on almost all spinner motors) no matter what you have it on.

Yeah thats what a meant to say, like it seems the fan takes longer to stop when the blades are attached.

A motor should still "glide" freely with no blades attach, and coast after it is spun. Of course it will coast longer with the momentum from the blades (this may not be the official physics reasoning but it's how I always think of it).

If it works fine, it works fine. If it does not it can be fixed.
