>1) Lower the quill. > >2) Look for a hole in the back of the quill. > >3) rotate the spindle so an Allen socket lines up > with the hole. > >4) Reach in through the hole, loosen the Allen socket a partial > turn, and reach through that socket to another behind it. > >5) Unscrew both fully, and draw out (trying to not lose them > inside the quill. > >6) Replace the front one (a dog point Allen head setscrew where > the dog point acts as the pin in the spindle. When it is set > deep enough (check that it does not bind on the collet with the > shallowest key groove), withdraw the Allen key slightly so it > only engages the outer Allen head screw -- which is *only* > socket and threads, no body beyond the socket) so it locks > the dog point one in place. > > Now -- I've only read about this, never done it, so I'm trying >to remember whether you have to turn out the big nut at the bottom of >the quill first. If so -- mark it so you can screw it back in the same >amount. It has its own set screw holding it in place. >
