But this afternoon I really am going to do something. Need to rehang the plastic over the doorway to the 3rd floor (it fell down day before yesterday) and 120-grit sand the last 2/5 of the hall way floor. Then drape the openings to the stairhall on the 1st floor with plastic-- not my favorite sport, and the animals won't appreciate it, either. Then, then, maybe I can start on the 1st floor stair treads. Nothing gets shellacked in there until the sanding is done.
Meanwhile, here's a couple-three pictures from the most recent work:
Where I cracked a groove during the medium sanding. May've had something to do with countersinking that nail beyond the board's tolerance.
Securing down that cracked groove. I used some small annular nails I had in my workshop, toenailed in, as recommended by various websites. Wish I'd used regular finish nails instead. It doesn't look too bad in this picture. You don't want to see how it looked after I tried countersinking those flat heads.
Ran my carpenter's pencil over the surface (actually wrote myself a monitory message) to keep from oversanding before I started the 120-grit fine-sanding phase. When the pencil marks are gone, it's sanded enough. Period.
How the part that's totally sanded looks. Pretty! (I think.)
