I think I would get some help and put the piano on saw horses, up-side-down. I get nauseous just thinking of working in it's current, position. I would use my power planer to remove as much material as needed, probing carefully for tuning pin ends and use a very short punch and heavy hammer to drive the pins upward. My planer has a bag to hold dust but I would think about covering the underside of the strings and have some compressed air ready to finish the job. (When the customer is not there of course) I would like to check the plate height, bearing, crown and try to determine why the block is so low. Did the "other person" leave out some shims or was the shelves cut down? If the plate has been lowered it may be best to back out of a job like this. :( Look this project over carefully before you commit to doing the job and double the time you think it will take to cut the block down. You can always give some back but it is hard to ask for more. Newton
