Technically this isn’t exactly a replica, since it isn’t an exact copy of a real device. This is something i built as part of a demonstration apparatus for the SPARK Museum.
The brass plate was designed in Illustrator & engraved using Cermark. The whole thing was then subjected to abuse to make it look 130 years old.
I started with a standard finger joint box, this one from 1/4” oak ply.
stained with dark walnut stain
added a couple of coats of clear satin lacquer. At this point it’s a new box.
buff with 0000 steel wool to give an uneven finish
add some dents using a ball-peen hammer, hold a screwdriver shaft on an edge or two & smack it with a hammer, lay a screw on the wood & smack it, etc. I try to do that in places where it would have likely been banged up during its life, such as corners & edges.
using a black sharpie marker, i add shading into the dents & around screws & hardware. Draw the shading, then immediately smudge/rub it into the wood with my fingers.
mix up a wash using a few drops of brown wood dye in water. I use a paper towel & brush to add streaks & shading in various places.again, depending on the use of the item.
That’s pretty much it for the wood. For the brass I use a liver of sulfur darkening solution to get the effect I want.
Haha… that’s the beauty of this mdf core ply, once it’s cut with the glowforge you can’t tell it’s plywood.
Plywood goes back further than you’d think though. It was invented during the civil war, although didn’t become mass produced as a building material until the late 1920’s.
I just used a negative image. The laser hit the background & not the text, so the when the cermark was washed off, the bare brass is exposed where the text is, and the background is black. Here is the original image:
