Just what us woodworkers dread- bits of hidden metal buried for decades in a tree trunk, to be revealed by a snapped saw-chain when cutting firewood- [ boy, do they fly! ] or a set of precision planer blades exploding in your face. A couple of months ago I was planing some sycamore and as the piece disappeared into the thicknesser I caught a glint of metal. Argh! Too late to stop the machine, I dodged to one side but nothing happened! Inspection of the piece revealed 3 beautifully planed 9mm lead bullets!
Wood work but can't!
