CHALLENGING SHAKU SMOKED

Hello!..a lot of work this week!..i've had the opportunity to work this beautiful japanese madake root,selected for make a 2.7 shakuhachi,but there was a big problem..the section marked in red was cracked,and for me impossible to fix,with a good result.
So i have decided to go for a 2.7,but joining the two parts,just between the fourth,and five hole,i was lucky because i have saved the piece above the third hole.
I know this is not a "how to" method,the joint by tradition is not placed here,but i think the result will not disappoint me,this is the plan:cutting away the cracked piece,hollowing out each,carefully measure the two parts together,handcraft the joint section insert(by the same bamboo),carving each middle joint,make the utaguchi,tune the "RO"in both octaves,than,join permanently the two pieces with glue,and go ahead,like on a "nobe"piece.
I have decided to fix it permanently because i don't like flute with rings,and my idea is to "leave" this flute as naturally as possible:same madake section joint,a mixture of natural resin based glue,and same bamboo dust,that will guarantee a strong transmission of vibration in all the body of the flute...more pictures soon..
..cutting the two pieces..

..carving out the root..i love the smoked smell!!

..insert making..

..insert sanded..

..this adjusting must require precision,is a step of vital importance for the bore shape,and the right sound of the flute..

..two parts glued..i have carved a channel for bind it with the stronger braided fiber i have find,it has a breaking strength of 110 kg!..it's almost finished..darkbeauty..

..utaguchi finished!..

..finally finished!!...soon i will add the sound file..

NEW 2.75 SHAKUHACHI

Hello! work almost finished with my last big bore 2.75 flute..pitched in F..made with a very thick and heavy piece of chinese madake..natural utaguchi,i have applied a "marble like" ikigaeshi ("breath-return") because the natural section of the ring was broken from the starting of making,it's really confortable howhever.
I have add a light coat of a natural,trasparent lacquer;outside and in the bore for prevent mold and trouble with moisture..the tone is rich,dark and hollow..the khan register is a little difficoult to dominate,but still in tune with itself..

here is the sound..sorry for the poor quality i have recorded with hurry..
