I picked up a Craftsman 17" floor model that was a closeout, floor display model at a pretty good price (about $130 off regular) Appears to be very similar to Wilton's stuff.
The fit on side adjustment bolt to take the play out of the quill was very poor - stripped it out the first time I tried to adjust it. Tapped the hole to 7/16-24 and had a friend machine me a couple of new adjustment screws.
After that I still had real bad runout - you could see the chuck wobbling all over the place. Pulled the chuck and arbor out, disassembled and cleaned them up several times, still wobbling all over. In looking at the lastest Enco Hot Deals catalog the other dayI noticed that they had Jacobs Super Chucks on sale, so I ordered one, along with a Jacobs arbor, and they arrived on Monday. WOW !!!! Compared to the original chuck it was gigantic ! (see attached image) And they are both 5/8" capacity chucks.
Installed it yesterday ....... the difference is like night and day .... I haven't put the dial indicator on it and measured the runout but it definitely tracks much better. Money well spent in my book.
