Motor shift?

Motor shift....

Is it possible to have just a little motor shift? Or is it just the full blown center pole against the wall that I see from time to time. 

I ask because this is the second time I'd be reconing this particular sub and ive noticed that there is coil rub on the same spot. 

From the eye the motor looks perfectly aligned.

Is it a stacked motor? what driver? Your recone skills could be off also. I hate reconing. Do you shim it when doing it? or just glue er down? Its not hard to tell if a stack has moved. Show pics down the pole, and the motor please.

triple stack mayhem. I'm sure my recone skills are shit, but i get better everytime and this would be number 8-ish?

I shim, I have a big stack of shims from SQ. They ship 5-6 of the two sizes. They work great. 

None of the stacks have moved. They are all aligned. Its the center pole im worried about.

I mean thats gotta be impossible to tell. I need some type of tool so I can measure around it.

+1 to the feeler gauge idea.  

Sticking steel feeler gauges in a huge magnet could be interesting, I'm sure it will still work though.

Feeler gauge no doubt, but make sure its thin due to the curvature of the motor/pole piece... you dont want to use a 1/2" wide feeler gauge. We check air gap on industrial electric motors at work all the time. For any electric motor, an even air gap is crucial

Just get 300 series stainless steel (most are these days), non magnetic.
