Now I'm verging on territory for the Modified Traditionals thread, but I've done a 15 recover and a 66 blade delete, and I had purchased 3/32" pin stock. On one knife, I turned the pins down to fit, and the pull weight was the same or lighter. On the other, I drilled the holes up to accept 3/32". It was tight, had to tap it in, but that's kinda the point with this kind of pivot. The pull weight was the same, just as snappy. So are you saying that these 86s are already using 3/32" pins? Or that they're using the smaller pin size?
My entire motivation behind the larger pin is, to bring it back around to the 86 - I want a stouter pull. I've asked several people about pull weights when reassembling, and they state that smaller pins would lighten the pull, larger pins would weight it. Makes sense from a torque perspective - you have the same length lever now responsible for turning a wider radius. I would have been head over heals for these 86s, but I wanted a firm pull that matched the spirit of the knife. Heck, maybe even a bored out 1/8" pivot pin.
