Can anyone advise me on how to do this ? The owners manual doesn't say. I thought running the quill down, I'd see a space for a drift. The slots in the quill are there, but the taper goes in higher than the two slots. So I tried to unscrew the chuck it from the taper, thinking that would work, but so far no luck and I'm afraid of beating the chuck key any harder. I purchased a new 5/8 chuck (threaded) and it came with a #3 taper arbor to screw on so I can approach it either way - just can't seem to get either way to work for me.
