The sheets in the video show a list of the distances for the arc and the various areas influencing the frequencies, for each bar. Based on the paper by Ingolf Bork, Practical tuning of xylophone bars and resonators.
At ua-cam.com/video/QZPyBDtoYc0/v-deo.html you can see 2 sheets of paper above the bar: the first is the table, and the second is from Bork's paper. The diagram in Bork's paper is expressed in relative lengths, since for the mathematical description of a bar, it does not matter how long it actually is. Bork's diagram says that, for example, material is removed from 20% to 70% length, this mostly lowers the fundamental frequency. When using the actual bar length, you can compute the actual lengths where to cut/grind - that's what I did, and this is the first excel-table.

what are the papers in front of you when measuring the bar?

I have the papers from ingolf bork.. but I don't have the one you're using to determine where to begin and end an arch. How are you determining that?

thank you so much for this video!
Thanks for sharing
tuner that program is ?
+Sergio Trujillo It is baudline: www.baudline.com/. I've found it very helpful during the tuning process!
