That is just the beginning. Next would be to put the assembly into the wood body and glue them together and then align it with precision instruments and an alignment grid. If not perfectly aligned, then you have to do it all over again and maybe even chisel some wood. That is one of the reasons why Koetsu rebuild is expensive, the labor needed for small pieces of components, to remove it , refit it, realign it and repeat the process if something fails to be perfect - skill, instruments, and experience are all needed here. It's not a snap and pop operation by any means. One reason why in my experience, Koetsus can last almost forever (unless you shock it), my Black 8 years, Rosewood Signature 12 years. All sold in working condition when I upgraded.
