I'm going to have a rather delicate carving for the rosette in the instrument I'm working on and I'm thinking I'm going to need something to back the spruce to give it a bit more toughness. I seem to recall that perhaps lute makers hand carve something similar and I'm asking for some advice to select the backing.
This is cut on a CNC so I do have a depth limit on how thick the backing is. In my test run, I used manilla paper from the art store that's probably about .010 thick and I'm not happy with it. For this test run I just used titebond to adhere it and once on, you could peel it away leaving just a super thin layer.
Any thoughts on what I should use? I'm almost wondering if I should use some sort of thin linen or something.
