This really is an ancient bit of kit but the plumb bob is still absolutely essential to the modern timber framer.
In essence, just a weight of any shape and form attached to a thin enough line, which when dangled over two stacked up timbers, forms a vertical can line. If the timbers are out of plumb, the discrepancies can be marked with reference to this vertical.
So utterly simple and brilliant, this is probably the one tool I will choose as my luxury item when I’m invited to appear on Desert Island Discs.
