A couple inches. Nothing on the sill itself, but I have a tendency to prop
things on the concrete block foundation wall just beneath it. Not a great
place for things, so I'm trying to break that habit by making specific
places for the things I usually put there -- can be anything from a
shooting board to unused trammel points to the scrap blocks I use for
protecting items being clamped or uh, held fast.

I have, however, taken a note from the Schwarz and hung chisel racks and a
shelf for layout tools across the windows, which I've found to be very
handy. Although I have to be a bit careful opening the window on the right
in nice weather.

Here's a shot that shows the idea, with a bonus incipient Saalburg bench in
progress last spring.
