Am here......sorry for being late.
will give you what I do.
1. strip all meat off bones - I boil and remove wing feathers for other projects
2. cut knuckles close to the end. (see black lines on photo)
3. end view of before and after of Ulna bone and radius (moutpiece)
4. soak these 24 hours or more in sodium carbonate solution (1 cup sodium to gallon of
hot water) [loosens marrow and gristle]
5. Clean marrow out with a bottle brush and a pipe cleaner - Big hunrous bone strip as much gristle off as you can.
6. soak 24 hours in 3% hydrogen peroxide [whitens bones]
7. rinse and let dry.
Now look at this first picture. You can see how I pieced them together. For the big Humorous bone [trumpet end] it has a lace work of bone (not marrow) and I remove this with a dremel tool and a conical grinding stone that is cone shaped. You actually will be grinding and the tone of this horn will change when you have just the right amount of bone lace work removed.
bits I use in the Dremel
8. I sand on a bench belt sander to flatten ends.
9. I take the ulna and cut a pice off to where it will almost fit. I sadn this down to fit on the belt sander.
10. one end of you radius bone (mouthpiece) is taper more than the other. This is the end you should use for the mouthpiece. The other end is inserted into the ulna. Dry fit and tune. You can sand the horn or the middle bone or the mouthpiece bone but not the end use suck on.
11. I then mix clear epoxy and glue
12. support call and don't worry about excesss glue.
as the picutre says I use the grinding stone on a dremel and grind the excess epoxy away.
That is it!
I do add a stainless screw eye for a laynard hook. People do not glue but thread wrap like wrapping eyes on a fishing rod. I do add art and it is done with rapidiograph pens and india ink.
I ain't that hard....really!
