I am considering using this bridge blank. Do you think (from a structural stand point) that this is too much sapwood?

I should note that the sapwood is wider on the bottom side. So, as I carve, more will be revealed.

Nothing wrong with sapwood. I like the look. :) It can be used. ;)

Depending on the wood species, sapwood can be softer than heartwood, but strength should generally be the same. Dimensional stability, or how much the wood moves with changes in humidity, can be different which could in theory cause some problems, but in practice would likely be OK.

I contacted the customer about this bridge blank and she decided that it was a bit much on the sapwood. I will save it for another build.

You still have the cut-offs? Measure de density of both, heart and sap, and you'll see if there's a big difference.

I built this Pau Ferro tailpiece a few years ago. No problem structurally. I like the contrasting look of sapwood.

Funny you should say that.....I've got some birchbark stashed from my time in upstate NY. Trying to figure out a way to use it as an inlay of some sort. Really beautiful stuff but I don't think it takes well to sandpaper. :( [headinwall] [uncle]

In Japan there's a long history of using cherry bark on various items, such as boxes. Images here:

I've wondered about using it as the head veneer for a cherry guitar. Not certain about durability, though.

I think the sapwood looks good, but you'd have to have a nontraditional design to go along with it.

I'm working with birch bark right now. I'm using it for a rosette. I like sapwood mostly on backs. I've seen bookmatched fretboards with a center of sapwood that look pretty neat.

Not a guitar, but here's a pear wood one I did a couple of years ago. It has held up well, as far as I know.
