If you remove the qc 30 lockring you can take the driving dogs off the bottom of the spindle(each dog is retained by one bolt),you could then use an old int30 tool holder and some cutting paste ,maybe valve grinding paste to lap the taper back.....you would obviously want to put the paste on the high spot areas first to bring the non contact areas back into line....i used this idea on a gear shaping machine with good results....its gonna need a good clean out after though! |
