Sanding, dust and mistakes!

Wow! Lesson learned - There's a time to NOT use an electric orbital sander especially on the back of the neck or headstock areas!  

I used 150 grit flintpaper and it ate wood real  FAST!

Here's some more shots of the sanding exercise:

Need to fill that gap with some wood filler, but the Home Depot stuff did look like it would work so I'll make my own filler by sanding some raw mahogany to create the saw dust to mix in with wood glue and stain.  If it still looks crappy, then I'll just sand the gap area flat, don't like doing that since it'll make that part of the neck thinner and not as strong.  We'll wait and see.

Here's what I ended up using instead of the orbital sander, it's simply a block of hard foam with the sandpaper wrapped around the block.  It's soft enough to take on the contours of the corners and rounded areas.
