Re: Rocket Science.

I believe Mike has the right answer. If not the other option is "rocket science" and that's toooooo complicated along with measuring the diameter!!!!!!!!!!!!!!!

Re: Rocket Science.

Having taken Mikie's advice (well before he gave it)I might be more off balance then the fan. How could you achieve balance With 5 blades that are not positioned semetrically? The blades aren't even positioned equally around the center. Unlike the mass on a drive shaft or wheel, the weight of the 5 blades aren't even close to being positioned 72 degrees apart.(360 / 5)
or, what am I missing?

Re: Measuring the diameter of fans can be tricky..

truly sorry about this Mike... I don't do this very often but when it happens it's kind of like watching a cat cough up a hairball. If I were there with you to draw a few pictures in support of the whole thing it would be much easier to follow. It's important to note that I AM NOT advocating that we try to "balance" one of these fans. I do not think it is possible anyway with the blade placment as it is.

Anyway, if you started with the beast at 8:00 this morning you may be in the right frame of mind by now to understand my previous post. Read it again if you dare....

I just measure half of the fan, or from the end of one blade to the center of the middle hole, then multiply by two.
