I bought a 1221 and stand on Black Friday - taking advantage to the price breaks Jet was offering at that time. Due to a variety of reasons, they have been sitting in their cartons, untouched until today. I started the stand assembly of the stand, and that's when I had issues.
The base of the legs are tapped with a M12x1.75P thread, with corresponding bolts. The kicker was, the bolts would not thread in to the holes, or cross-threaded if they did manage to start. I have some metric fasteners on hand, but nothing in the 12mm range, and with it being New Years, there aren't a lot of stores open for replacements, if I was so inclined, which I wasn't.
I looked closely at the threads in the legs, and there appeared to be globs in each. Paint should have been cut by the bolts, so there was something else there. I have a set of thread repair taps /dies I bought years back to fix a lawn mower issue. Got those out, ran them thru the legs and the bolts. Both legs produced slivers of steel about 1/4-5/16" long. The bolts were black, but each of them had a thread which turned silver after I used the die on them.
Once this was done, the bolts threaded fine.
A couple of other oddities - the assembly instructions make no mention of the cross brace between the legs. It's shown in the parts list, but you are never told to install it. Another is the fact that some of the supplied hardware (screws) is threaded for 5/16"x18 threads, with a recess in the top of the screw for a allen (hex) key, in 5mm.
Got the lathe on it, fastened down, and that's all I had time to do - more tonight I hope.
