A while back, I scored an older Buck 6" 6-jaw adjust-tru chuck for a reasonable price, but it needed some attention. It came with both inside and outside grip jaws, and the outside grip jaws were bell mouthed pretty bad. Did a search, and found these folks, https://www.kzoochuck.com. Sent in the chuck, and a few weeks later, it came back good as new for $150! He re-ground the OD and face of the chuck body, and the key surfaces of both sets of jaws. Awesome folks to deal with, and quality work.
