That chuck cradle, or sled, is really slick. I just use an old scrap piece of two by four on my Atlas 618, but then my chuck probably only weighs about 1/3rd of yours, so is much easier to handle and lift. I know on the Okuma I used to operate, changing out the chuck was a two-man job, partially due to weight but even more so due to the awkwardness of it. Having a system and a dedicated tool like that sled is just plain SLICK, and plenty smart too!
