I made these frames with quartersawn white oak, incorporating through mortise and tenon joints and leaving the “horns” long. I pegged each joint with brass rod.
For the finish, I wanted them to look old and weathered. To accomplish that look, I first attacked them with a wire brush wheel chucked in my cordless drill to really dig out the pores in the wood. Since the medullary ray flecks are a harder wood and don’t have pores, this helped them stand out some. Next, I fumed them with strong ammonia (getting harder to find, by the way, now that the blue print machines that use the stuff are disappearing). I then chemically stained them with a vinegar/rust solution (recipes can be found online), which reacts with the tannin in oak and many other woods. In addition to “ebonizing” the heartwood, this made the sapwood pop, as it has less tannin content. Finally, I applied a coat of tung oil varnish, followed by a couple coats of shellac sprayed on for good measure.
