I've found there's also a difference in volume between portions of the plate that are in agreement with the center of the plate and portions that are thicker and further away. This is most apparent to my ears when listening for the sound as it echoes back to me after interacting with the room.
Thank you Peter. The problem is that with big surfaces you can get lost somehow.. What I find difficult is to establish the height of the arching. How long should the surface that has the similar scratching tone should be? And should it be exactly between the C's or a little lower?
I made a video on how to set the arching height. 22A . I don´t try to set the top of the arching at a special place. It finds itself. What is important, is to understand that the differences in pitch at the top of the arch, is very minute and you really need to be LISTENING.
Hi! I guess you mean the inside graduation. If so, I think 5 mm is going too thin as a starting point. Wood can be very different and other factors also play in, such as model and arching height. I would start at about 6 - 6,5 and then take off material until the outside knocking matches the inside knocking. I always start with the top, first doing the outside arch and after both plates are arched, I do the top graduation, then the back. I have no desire to reach a certain pitch, such as C#.
@@westerlundsviolinverkstada9892 I have a used cello, old and disassembled. Is it possible to make "internal" adjustment on the plates of a used cello?
@@mauriciomuller1972 It could be an improvment but if it is an original work form a known maker, it is a big NO! I never alter another makers work. If there is a problem, I contact him/her for a discussion. If they are deceased you have a very big responsibillity.
Thank you for investing lot of effort to make sure we can hear what you hear! Very generous of you!
Ah, very nice, a demonstration using a cello plate! Thank you!
Excellent explaining!! Thank you!

@@westerlundsviolinverkstada9892 thank you!
Good morning ! Does this tuning method work for instruments made with common woods? Example: Araucaria angustifolia?
Yes. It has actually nothing to do with what material it is.
Good morming ! Should I start by tuning the top or bottom of the cello? Should I start in the center? using C#? I start in the center with 5mm?

@@westerlundsviolinverkstada9892 It is a factory instrument. No author. So I dismantled Cello and would like to try tuning the caps
