The basic structures of the built-in are complete and in place, so the next steps are about details, lots of details.  Therefore, the posts will probably slow down to more of a trickle over the coming days.  When last we met, the first bookcase was up at long last. 

Yesterday, the second one was assembled.  I had already cut all the pieces, including the parts to box in the pipe that runs up the corner.  I used my original, mis-cut base platform...
...to make the parts to surround the pipe in the corner (odd how they've always been exposed).  To cut that big board down, I had to make a couple feather boards to keep thinks tight to the table saw top:
I know it sounds silly, but this is really the first time I've really needed to use feather boards - after all these years.  Like said, I cut the pieces to box in the pipe, then came the complicated parts - assembling them.
That part was not fun - at all!  But it worked out just fine, and once I put the caps on the bookcases, very little of the pipe will show.  Here's a closeup, so you can see what's behind there, and why the case is built the way it is.
