Cartridge Alignment HELP


I am trying to align my new Ortofon 2M Blue cartridge on my Audio Technica AT-PL120 turntable, but I don't know how. I understand that I can use the protractors posted on Vinyl Engine, but I don't know how to use them. I can't find any videos or specific instructions; the closest I can find just say to "align it."

But how? How EXACTLY do I align my cartridge?

You might consider purchasing the Michael Fremer DVD on how to setup a turntable. I purchased mine on Amazon for twenty something dollars.
G'day all, yes it takes a while to become conversant with the basic concepts of overhang set up but once it does become clear, it's like a relevation!

I find the two point protractors very easy to use and give consistent excellent results. They are my recommendation. Regards, Fap.
