TW-Acustic cartridge alignment HELP

Does anyone knows how to use that tone arm alignment card correctly?
I don't understand what is the correct way to align the axis?
Hope to find a step by step guide on this one.
This may not help, but I didn't find the TW card or the pivot to spindle distance tool very helpful. I used the card only to roughly assess VTA by looking to see how level my tonearm was initally before dialing in VTA.

For pivot to spindle distance I used the Feikert tool and for the cart alignment I used a mint protractor.
I use the Feikert and Mint too. I think all you need is the Mint but the Feikert is useful as well.

I have another arm in use right now but I recall that once I had the Raven arm set up, it hit the 15.8mm line spot on but I don't recall exactly where. At the arrow or closer to the spindle?

Philb7777 where does your stylus hit that line?
Right on arrow at 15.8. The Fiekert gets the same results on overhang.
That is what I wanted to ask. Should I point the line at the vertical axis of the arm or should I parallel the arm tube with the line when doing adjustment?
Point the arrow toward the pivot point, and then move the arm until you can assess overhand on the grid where the numbers, including 15.8 are. In a sense, you will wind up with the arm not quite parallel.
Luna, I forgot one thing. There is a single small round hole in the area where you mount the cartridge to the tone arm. Use that to set the pivot to spindle distance by having a loose arm board where you can center the hole on the platter spindle. (Cartridge must be off) Then tighten the arm board. That eliminates the need for the Feikert. That is slick.

Then follow Philb7777 for setting the overhang by hitting the 15.8MM line at the point of the arrow.

That is a slick way for spindle to pivot distance check. I never noticed the small hole in the tone arm end of the TW!
Thanks guys, I am giving the mint protractor a go.
Luna, the mint is a great protractor. Get good lighting, and have patience and you will be rewarded, no doubt!
