If this MP4 video streams to slowly, go to Nick's Nifty Key Leads Program (flash). 'Tis better stream, but less quality.
When weighing off a newly rebuilt grand piano keyboard it is highly convenient to know which existing key leads to either pop out or else partially drill out. Knowing this saves time and money, not to mention the avoidance of confusion, frustration and poor outcome.
The compliment to this video is an excel spreadsheet which calculates for each key the amount of lead to be removed so as to achieve a target downweight (or balance weight). Go to www.gravagne.com/NNKLP.doc for more info.
