Who's of you make flat spot on motor shaft??

I find it impossible to run without a flatspot... before I make mine.. I tape up the whole motor, and put the shaft on a vice... and I use a metal file.. seems to make a nicer flat spot that a grinder/dremel....

That would almost be called manual labor. blasphemy.
