This is a real Danelectro Silvertone 1452 from the 1960s. When I got it, it was a sad box of parts. Some hillbilly had stripped it, by rubbing it on the sidewalk, I think. The fretboard had delaminated, and the old repair had simply made the problem permanent. I repaired the neck and fixed all the other issues, replaced the lipstick tubes, which had split, and clear-coated the whole thing in modern poly. I was not able to fully repair the neck, there's just not enough wood left, so I don't keep it under tension. The pickguard is stained dark for contrast. I cleaned tarnish off the old metal bits with oven cleaner, and replaced all the corroded fasteners with shiny new stainless ones.

A subject so simple you hardly even consider it, yet really very mysterious. Just what is the roughness of sandpaper, and the relation to the number on the package?

Here's a plot of some numbers I found online: sandpaper "grit" versus actual micron size. Interesting to see what size scratches you are taking out ( or putting in. ) The curve starts at 320, which is the coarsest grit that might be considered part of the finishing process. For final finishing like orange-peel removal, I start with 1500 and work up from there, I find that even 1000 leaves scratches that are difficult to remove.
