Mark Story responds to John Musselwhite: >Yes, try it John. You may discover what I did - that pins heat up less = >if extracted at 500 RPM than if you take them out by hand. It sounds = >odd, but I guess it's because you get them out in one or two seconds = >rather than twenty or thirty - less time to heat up and glaze the pin = >hole. I remove pins with a high speed pneumatic wrench. The pin is actually cool to the touch right after coming out of the block and then is too hot to hold in a second or two. I think it was Brian DeTar who suggested to me that the heat transfers from the surface of the pin to the center, keeping the surface cool long enough to get the pin out of block. Whatever the explanation the block is left in great shape without any glaze. I still like a fresh block with 2/0 pins though. Scott Scott E.
