I’m new here, and a bit of a newbie to woodworking. I am hoping someone can help me select an appropriate method for finishing a project that I’ve nearly completed.
As as spare time hobby, I’ve been creating a 3D sculpture made from white oak. The sculpture is made from many (30) oak tiles about 2×4” glued together to make a hollow structure. Each tile has a lot of very fine detail carved into it using a CNC machine (to a depth of about 1/4”). I’m nearing the point where I can glue the final pieces on to close the structure up, and once that is done I won’t be able to access the interior of the sculpture any more.
I need to select a finishing method to achieve the following (in approximate priority order):
1) Protect the surface from dust and fingerprints/stains. The sculpture will likely be picked up and handled (although I hope to limit the handling).
Other issues that I need to consider:
5) The surface is not smooth as you would get from sanding: even flat areas of the tiles have fine ridging from the passage of a small milling bit (ridge width would be around 1/50-1/100”). I actually want to preserve this texture.
Given these restrictions, I’m figuring I probably have to go with an oil finish (boiled linseed oil) which – while it won’t offer a great degree of protection – might be enough to prevent fingerprint stains. I’m a bit nervous about the tendency of linseed oil to stain the wood. I am wondering if there is a thin colourless water-based polyurethane that might apply that produces a matt or low-gloss finish?
I would be very grateful for any help or suggestions from someone with more experience than myself (which – face it – would probably be everybody here).
