Upright pinblock removal

[Farrell]

If you have an upright piano with a full plate, why would you want to use the old block as a template for anything? I commonly find plate/pinblock screws and tuning pin holes that are not well centered, etc. Is it not a good opportunity to do a better job than the original effort by "out with the old and in with the new"?
