that was a bit interesting- compact chuck flew apart
Cup of tea needed after this one. Using my little compact chuck I tightened it up and started turning then.... zing crash bang. Bits of chuck everywhere. After retrieval of pieces, non from my forehead fortunately, I realized what happened. These chucks are held together by a split ring in a slot behind the tension ring thingy. It had somehow slipped out and let the back of the chuck come away from the body so all the chuck segments did the centrifugal force thing and flew out. :C All reassembled now. No harm done. But I now know what the inside of a chuck looks like. And now also own a pair of split ring pliers. And will also be keeping an eye on the split ring a bit more.
