|
|
Completed my rib and bout assembly last week. I have a nice piece of maple burl that I would like to use for the back of violin. I know maple is ok for this but not sure about a slab off of a burl. The pictures at the end of the link below show my progress to date but I have no pics of the burl I am speaking off. Thanks in advance for this....wayne

Burl is very dense/hard and generally non-resonant. Not ideal, in my opinion.
Even Birdseye Maple is generally considered unideal in most cases. Burl usually lacks consistent structure and texture. _________________ Leif Luscombe

No, use maple or pear or even beech, birch, or walnut, but not spruce. |

The other problem with burl wood is stability. |

I think you had best try a more stable would for your first violin.
I had a violin with birds eye maple on back and sides. I had to remove the back the top and repair many cracks. I had a lot of truble keeping the wood strait. I had to make a form to champ it to and then steam it and let it dry . all befor I could glue the back to the ribs again. I had to make a form for the ribs in the same way. Just to hold it in position to glue. I had some cracks in the ribs and the only way I could keep them toether was to add a thin piece of wood on the inside.
I think it has a good chans to still crack again. |
