    Another vote for card scraper.
    Why sand? Negotiating a vibratory device inside a corner takes more finesse than a few strokes with a slow motion scraper. No cross grain witness marks from the scraper.
    No project too small or too expensive.

    A multi tool will handle it quickly but the others have good hand tips....BEST to sand prior to assembly..

    I already own a 400 EQ, Jason. The problem is that is it an orbital sander and cuts grooves into the adjacent surface when sanding tight into the corner.

    I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

    As I mentioned above, I'm working with interlocking dado joinery on wall shelving. I'm finding this type of joinery requires post assy wood filler....pre-assy sanding doesn't solve that problem. I'll post pics later todat, maybe that will clarify what is is I'm stuck on.

    Thanks for all the helpful responses!

    John, the linear sander solves the groove problem, but I'm dealing with grain that is perpendicular to the corner and that linear sander would cut cross grain.

    Sorry Scott,
    I missed that you mentioned the 130 in your second post.
