[TheForge] A Balancing act

[Ron Childers]

If you use the knife edge, it has to be absolutely level and no breeze. I bushed a bearing with tape to balance an airboat propeller.

Without doing a lot of dismantling can you see into the impeller in any way?

If so examine the impeller for debris.

I have solved quite a few unbalanced issues by removing something small. 
Once even a piece of tissue paper that had bridged a few sections of the blower.  That one I could actually see bouncing around as it ran.

It does not take much.

Dust, especially greasy dust, can accrete  on the impeller and cause it to go out of balance. Scraping or pressure washing does the trick.
