Hydraulic been on hold since March 2013.
Point being you can drill through whether chucks or jobs got runout and be accurate. That's out the jaws about 6", I could haveclamped it up at 45 degrees and still done the same.
Andy when I use the small clapped out chuck, centre drill if you must I don't bother plough straight in. You can pull work piece out from chuck and push to revolving centre in to cr drill hole. Lightly nip the chuck and wind tail stock in a bit pushing work piece back through the jaws, works 90%.
Dunno if I am the only one but cr drilling then drilling have encountered runout often, plough straight in feeling for whats happening you may be surprised.
