I mostly worry about a pin driven in at a less than perfect angle, enlarging the hole. There is no room for this kind of mistake. I also don't want to scratch the plate with something that is too powerful.. I envision a bull in a china shop scenario and don't want to negate the quality/integrity of the tuning pin hole, or my plate finish. Thanks for any ideas.
