Butternut lumber - Ken's Corner (Bass Forums Sponsored By KSB)

How would Butternut lumber work for the ribs and back (carved), on a double bass?

Its exceptionally lightweight, easy to work and is also pretty attractive. On the other hand, It is not very dense, so it could make for a very fragile instrument.

I have had some sitting in a barn for years, not sure if its too "experimental" for bass building. Any thoughts would be appreciated.

It is a bit low density is my first impression. Compared to your cherry it is the other end of the spectrum. Density is around 24 lbs/ft cu. Cherry is 45-55.
Measure its density or Specific gravity compared to water. I will tell you how later if you don't know.

Butternut is a nice tonewood, IMO. I saw a nice bass by Ed Maday with butternut back and ribs. I believe it behaves similar to a real poplar (not tulipwood). I have a stash of it myself, though I doubt I'll ever get to it.

The density of Butternut is around .38. About the same as Basswood, Western Red Cedar, and Willow. I got the idea, after seeing a Shen "willow cello" that was super light, and had a smooth tone.

One advantage of Butternut; It carves very easily!

Craig, Butternut can be very beautiful wood, I have used it for some carving and furniture before. If you have some that measures 38 lb /cu ft then it should be pretty close to willow which is obviously a good tonewood.

Did you measure the density of your wood at 38? Can you show a photo of it just for yucks?

Oops, I did not measure it myself! I just googled "Butternut wood density" and got 17,600 results, in .44 seconds. Here is one:

It would be interesting to do the calculations myself, how is it done?

Pics coming.

Here is a photo of the Butternut wood. This piece would be for the ribs (4/4 stock).

I wet the board with water, so the grain and color, would be more evident.
