So this is the second place I decided to incorporate copper into. This is the butt of the guitar and how I inlaid the copper was by first filling the pores of the ebony, then making holes with an awl where I wanted the copper. I then made copper filings (because I thought that actual dust would just float out with the superglue) then I filled all the little holes with the filings, drenched it in some superglue and sanded it sound to flush. When it gets sanded I sand through some of the filings which gives them a really nice shine.
I use this method a few times in this build - I have better pictures of the process when I was doing the headstock. I'll post those in the next few days. Cheers!
