Re: Easiest way to find the spine?
Here's what I do.
I take the fat end and balance it on the toe of my shoe.
The skinny end pokes into the palm of my hand.
With the other hand, I'll slowly draw a couple of fingers across the middle of the blank section, spinning it until it "pops". Then I mark the "pop" point with a grease pencil.
If you can't find the spline, then it doesn't matter.
IMO it doesn't matter what side you build on either.
