having had a chinese drill chuck with pretty poor run out (>15thou), I would personally look into buying a decent condition used Jacobs off ebay with a 3/4in arbor already attached. Or any decent drill chuck and a separate 3/4in arbor. I agree that it's great to save money and use what you have, but this is a fair amount of work on something that might not warrant it. Before doing anything I'd first check, if possible, how much run out the chuck has over its clamping range. If it's anything more than a few thou, I'd sling it in the "might use one day" box and get a better one.
