Didgeridoo making-instruction with bore-through-technic
Step 6, finishing



With this type of grinder the inner surface will be smoothed. Big structures will be stay there, and the hole will smoothed.
 
 
 
 
 
 
 
 
 

 

Here and at the bell-end you see it nicely, the bigger structures remain.
The inner diameter at the mothpiece is about 35 mm and a wallthickness of about 10 mm.
 
 
 
 
 
 
 
 

 


 

Without the bell and the mouthpiece the wallthickness is about 1,5 cm.

After we finished the surface with a big file and sandingpaper, we have to decide, how to protect it.
If we use varnish, the pich will increase a little.
On the knots there are often tiny slits, because it drys faster then the wood around it. 
Here I widened the slit and filled with coloured Epoxy-Glue. So it will stay tight.

The holes, I had to make because of the bend I closed them with other timber, the left one is Teak, the right is Indian Palisander. It is glued in with coloured epoxy-glue.
 
 
 
 
 
 

Here I used Robinie.


If you like the sound very resonant and sharp in pronounciation,you have to use 2-components polyurethan-resin the hardest surface you can achieve.
Better than Epoxyd-resin. You can believe me, I looked around a lot. ;-)
 
 
 
 
 
 
 

Now! it is finished without only the mouthpiece. In that case I use wax.
