The Arcoy Dovetailer.

Hanging beneath the rafters in Dad's shed is this strange looking metal object. I have watched Dad use this many times over the years as he built bookcases etc to go in the house. With the timber placed correctly into it and the appropriate cutter head attached to an electric drill, he was able to make sure that the joints on the furniture he made were beautifully dovetailed. I hope one day to have a go and see if I can make use of it too..
