The great advantage of cordless drills and saws is the flexibility they give. The great disadvantage (if you don't have spare batteries) is that they run out just as you get 40 minutes into a project.
So it is that GF is sitting, writing this, whilst waiting for his drill battery to recharge. The project? Well, he has this picture in his head of some hidden lighting in the lantern of the Orangery. He has finally worked out how to do it, and started fixing an ogee moulding around the bottom rim of the lantern. When finished, he will fix an LED ribbon along to top (hidden) edge.
