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.
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.
