I did a little more experimenting with the tines. The size are basically 1/8 inch by .062 inch. So these are pretty chunky ones, and that is why I have had so much difficulty.
My experimenting has given me what I hope is the formula for the length. Just cutting them to the charts I have seen online does not do it. What I found is that each note is seperated by 4 millimeters, at least when it comes to those tines that are between 110 and 130 millimeters. As the tine length get longer, that amount (4mm) may be reduced some.
Also, based on my experimenting, the black key (tine) lengths are about halfway in between each of the white key tine lengths. I only discovered all of this, as I spent the time cutting tines every two millimeters
I then tried tuning them to the note closest, and for the most part, each tine ended up on the high side for each note, making me use my Dremel to remove some metal on the back of the tine about 50mm from the ends. Once I got close, I used a curved file to slowly cut away the metal until I hit the note.
Maybe tomorrow I can cut the next octave set which will be more than likely in the 130-150mm length range. Then I need to go back and cut the first octave set, as the first ones are of varying lengths, and basically do not match. I need to get that 4 or so millimeter spacing so that they flow properly from longer to shorter without having some stick out..
So much fun, and it doesn't guarantee that the tines will actually sound right to the ear. They just sound right to the sound meter..
