Looking for a unique way to add a nice metal inlay to finish off your project? [Ben Krasnow] shows us how using a CNC router, a bit of solder, and a lot of sand paper!
It’s actually a pretty simple job — Of course, that’s only if you have a CNC machine. [Ben] started by engraving his inlay using his handy CNC mill, and then sanding off any rough spots. He then filled the engraving with acid flux paste, got out his MAPP gas torch and started dripping solder into the piece. Once everything was covered, he started sanding it, from 60 grit all the way to 600 grit for a nice polished finish. The results speak for themselves.
An easier method of this could also be achieved using plastic and epoxy, instead of brass and solder. One of the biggest problems with the solder is bubbling, which can cause voids which will appear when you are sanding — so you might have to do a second pass with the solder.
[Ben Krasnow] is an interesting character. He’s sought out the perfect cookie, made his own CT scanner at home, explained the various heat treatments of steel — and even installed LEDs into his contact lenses just for kicks!
