I am about to destring 1919 upright (my first attempt at rebuilding, or at least a partial one). When it comes to removing the tuning pins, Reblitz recommends the use of a variable speed drill, but he does not suggest high or low speeds. I would assume a lower speed is best, but the pin would then remain in the block for a longer period of time. I am not planning to ream the holes after, as the pins are reasonably uniformly tight. Besides, I only have a heavy drill, and a previous discussion on this list highly recomended a light drill so that the drill takes the direction of the hole you are reaming.
