Adding weight is indeed "the trick", but you keep referring to 20 grams. That is a small amount but a good reference point. What you will need to add is what the key requires. Since you have the full chart you can look up what the key weight should be based upon the desired BW. I have not had the time to do any analysis of the numbers you sent yesterday but I should over the weekend. The hammer weight numbers look all wrong to me but I will know better after plotting them on a graph. From those numbers I can use a quadratic equation to determine what the weight could be for that set. This then will determine what the BW should be for each key to get the balance weight you wish to have. This is not rocket science, just seems that way. I am not one that can visualize a graph by looking at a column of numbers. I have to look at the graph to know what is happening but I need to use three separate computer programs to come to conclusions. Have more fun. Newton
