I’m not sure what to call it... and that’s the problem.
What is the stuff some folks use to line the inside of their sound ports. It’s usually black ... not binding, but it’s something that goes down on the inside just a bit...
Sorry for the janky explanation....

Are you thinking of the fiber sheet?

It’s what I have used after reading the article from Jay Lichty in American Lutherie.

His example was a Uke, that’s where I use it too. I haven’t put a soundport on a guitar yet.

Hope that helps.

Fiber sheet is really handy for adding purfling lines to head plates, heel caps and similar. I've never done a sound hole and if I ever did, would probably reinforce it with a piece of wood with the grain running across the sides - might put a piece of fiber between to add a contrasting line (especially if I had done that at the head).

Are you asking about lining the edge of the opening (like binding the edge of the opening) or lining the inside surface of the side surrounding the opening?

Hi:)
No I’m talking about a lining on the inside that protrudes down a half inch or so. Maybe not quite that much even.

I use leftover 1mm or .040 maple or birch veneer, to line the inside of the soundport on my ukes
