Hello there! As some of you know I am making my first accordeon and You have been really helpful with all my process!
I am in the reed blocks part and I am going to do the body from one piece with the table saw.
So, here's my question:
What's the way of thinking the different volumes of air the different reeds need? How do I have to decide the depht of the cut?
I hope this is understandable..if not please let me know, I'll try explain in anoter way... (i'm not an english speaker)

Thank you very much

I may be wrong, but in general I think the depth of the chamber for each reedplate is a function of the clearance required for the inside reedblade to oscillate freely at maximum volume without hitting the bottom of the chamber.  Since the other 2 dimensions are dictated by the reedplate size, the volume of the chamber is more an end-result than a design goal for acoustic resonance or whatever reason.

There are also practical considerations: tapering the blocks facilitates tuning in place and helps avoid outside reeds hitting the adjacent block.  Also, the bottom depth must match the pallet hole size.  And special consideration is often required for the highest 2 or 3 treble reeds.

I'm also in the process of making my first accordeon.  I have measured a few boxes of the same type I want to build, and I use the numbers as a rough guide to help  decide on dimensions for my own box.

On the one row box I just built the low end ( large reeds) had a depth of 7/16” 0r around 11 or 12mm tapering to high end (little ones) 1/4” or 6mm. equal depth on the reeds blocks that were glue flat to fondo and tapered slightly top to bottom on the standing blocks. Everything cleared on mine.
