Yes I am in the process of self teaching string making as well....
I made a stretcher jig and put twist in the string before stretching, stretch it out overnight at a desired length with an idea of how much it's going to spring back. Doing this I have found that the string is much more less likely to 'Slinky' so to speak and I have a twist count that I am happy with.
I make about 3-4 strings a week just to throw in the garbage, I log down my results along the process so I can duplicate or refine later on.
This is all not necessary at all, it's just me being anal retentive and enjoying the process along the way, YMMV.
Anyway back to the question.
Is the Bear wolverine a Pre-1959 bow? with the grip more straight than the bows made 59' and later.
on edit; I googled Bear Wolverine and see it's a new Bow offered from Bear, The grip is forward leaning thus bring the most inside part of the grip further away from the string. This is why I was wondering if maybe the Pre _59' bows would need less of a brace.
Nice looking bow btw.
