That's a lot of posts on string up a sixer.
I figure twice as many for a Rick12?
I simply start with the low E, guitar lying face-up on padded flat surface, cloth scrap under the tailpiece. Slip the ball end under the tailpiece and pull until it's hooked. Maintain a bit of pressure and decide where to cut (I cut the string 1 1/2 tuner posts past the one I want to pull the string through). Cut the string and run it through the post. All the while I'm maintaining string tension a bit with my right hand (I'm left handed). I then grab my winder, which is always close at hand, and tune up a bit--not all the way.
I repeat this with the high E.
Then I fill in the other four strings in any order. Time to tune to pitch.
No tape, no capos, no hardware save my nippers and winder.
Twelves I do the same way: both Es (low E, unison high E) first, but then I fill in from outside toward center of fretboard in order:
High E, octave low E, unison B, A, B, octave A, unison G, D, G, octave D.
This keeps all of the strings in the proper over/under order at he headstock. I don't use tape anymore for 12-string Rs either. The only time I use tape is when restringing Accents, which can be a trial without something to hold the string ball ends in place.
Sometimes it helps to hold the string firmly and bend the ball-end up slightly (about 10 degrees) from about an inch to the end, so it hooks up and into the tailpiece easier.
