OLFers, any of you bugged by ill-fitting pins? I am. We grab a drill bit and poke two holes through the top and position the bridge for gluing. Usually that bit is a 3/16ths inch bit. As you know, the end of a bridge pin is way less than 3/16ths allowing the ball to creep into the cavity of a slotted pin and the bridge plate. Why don't we make bridge pins straight, a perfect 3/16th's of an inch? With a 3/16ths hole, it would kick the ball out onto the plate. Secondarily, why not just kiss the slotted pin goodbye and slot the tiniest place for a string to go through the bridge top and lodge on the bridgeplate. Surely the contact with the pin would keep it right where it needs to be. Oh, I have a wee problem pushing some ball ends through a 3/16ths inch hole. Does anyone else have that problem. Those were 80/20 M150 Martin Acoustics . Your thoughts?

First, the bottom of the hole is a perf3ect fit in a 2well fitted pin setup. The pin extends into the body. The taper takes care of filling the hole. Second, a straight pin wouldn't stay straight long, as it would wear. then we'd have a rattling pin setup... Third, your last description is that of a well fit unslotted pin setup. Once tuned, you can pull the pins out of my guitars and keep them in your pocket all day long.... Martin's balls(no pun intended) are a tad larger than everyone else's. Nothing new, Bruce, sorry <bg>

Yep the taper of the pin is the securing device. Much like the spindle on a drill press or Wist in on a pumping unit but I doubt many of you have dealt with a wrist pin on a pumping unit

What Grumpy said. Slotted pins were invented to speed production in factories.
