Share your tricks to centering a blade in scales.

[Gasman]

I bet a lot of us have spent the time making that perfect set of scales encluding the wedge, drilling the pin holes as perfect as can be. Then put it together and find the blade doesnt center. And possibly was out of whack so the edge hits the scale edge. I know ive ran across this a time or two. Or three or four or.....

So, share your tricks to help get a perfectly centered blade. Ive read about a few ways recently but thought it would be good to share with all. So that someday you might need this info and be able to find it. Not like trying to find something in the "what are you working on" thread.

So post up how and why with as much detail as possible. Some of us are a little slow (me) so we need simple but detail explanations.
