Any ideas how this chuck comes off? It's a CVA chuck, there doesn't appear to be anywhere for a drift other than between the chuck and the depth stop collar. The depth stop can't be removed until the chuck is removed.
as Doug pointed out, I stripped mine a while back, but I had to get some wedges to do it. I can't remember quite where they fitted, but there was certainly nowhere for the drift to go that was suggested in various places online. I got the wedges from either chronos or rdg tools.
