As an update, I was able to figure out on the #7 jig where optimally the frog point should be and scribed marks on the jig at that location. Then I figured out exactly where on the frog helper soldering jig the two halves of the frog rails should be for soldering and also marked the frog helper with a scribe at that location.
Now I am able to get repeated great frog points and install the frog in the right spot on every turnout I make. I then check everything with an NMRA gauge and file if necessary. I finished 3 turnouts this evening and they turned out great.
I will take some pictures tomorrow to show what I did.
