The attic floor needed finishing.  I could not do it before as first I had to build the attic steps.  The piece of floor that needed doing had to be fitted around the top of the steps.

Here is my wwoofer, Mogens, trimming a piece for the side of the steps with the chain saw.

And here he is hand-sawing a piece to fit.

Eventually the whole attic will be insulated.  I plan to make a library (I have well over a thousand books) and a spare bedroom.
