I'll second Larry's suggestion. It will be the last VTF scale you will ever need or want.
One thing that I have found to be of a most particularly troubling nature is the starting point. Do you start with the arm level? Or the cartridge body level? Etc., etc. Drove me nuts until Nsgarch (thanks again, Neil!)posted a methodology that is logical, somewhat easy to use and takes most (not all,depending on your eyesight) of the guess work out of this finding of a good idea of the starting position.
This is the thread:
How to set SRA after determining true vertical?
I won't go through it here, but I would say that if after reading that post the concept makes sense you will want to add a first surface mirror and at least a 10x (or a little more) magnifying glass to your tool box.
From there all you need is a good set of ears, either yours or someone you trust, and a tonearm with easy VTA adjustability.
Best of luck,
Dan
