Well for starters the name Jinlong turns up about as many different electrical companies as one could hope for and so far non make ST heads ( or will admit to it I guess ).
Here's all the pictures I have ready at this time.
http://www.putfile.com/dougwp/images/102508As you can see there was some damage to the rear end bell. Pat from Altopro Inc, the vender was kind enough to replace it. Its out there on a truck some place right now....
Notice the dog house is caught eyed, this is nothing just needs to be adjusted....
Here we are drying in the cool of Tuesday evening. The xylene and 2 coats of 1201A are going to take some time now to cool and fully cure. This morning it was still slightly tacky to the touch and notice the gloss, 1201 is a semi gloss paint but because it has been thinned and layed on heavy in about 5 coats its got a shine to it now. It will get at least 1 more full can of electrical finnish before I'm done to ensure all the winding is glued together as tightly as possible. Any wires that wiggle in the slots or knuckel will sooner rather than later wear threw the enamal coating and begine to short into the other coils. Notice I also went to the trouble to paint the inside of the case frame and fully coat all the laminations. The Paint will wick into the laminations if there are places it can. Loose laminations will rattle and hum, some machines will happily rattle for some time, others will not. Painting the inside of the frame is also good practice, it prevents rust and a smooth clean surface will collects less dust and fuzz making future services and cleaning easier. Also If a crack or probelem develops ona clean painted surface you stand a better chance of noticing.
Some guy wrote somethng In Chinese on the bottom, I wonder what it says?
Some guy didn't paint the bottom....
( but the clean rust free casting tells me the machine was never exposed to water or moister from the day it left the factory )

One more thing I want to add about loose wires and laminations....
If you own an arc welder try this trick, cut a small handfull of wire coat hangers bound with string at the center only as tight as possible. Wrap as many loops of cable around the center of the bundle as you can or better yet find some smaller wire. Strike an arch with this rig in series with your short stub at lowest setting and work your way up to some higher ones and watch the effect this hs on the bundle of coat hangers.
For those without a welder let me explane what happens
They dance and spread and try and push each other apart at the ends of the bundle.
The reason magnetic forces are trying to push the like poles at the tips of each piece of wire aprt from on another. These same forces are trying to push you ST head apart and this is why its so important to bind, clamp and glue together with varnish all the pieces could or would push themselves apart. All the torque and force exerted on the shaft are also pressing diirectly on every other part or indurectly threw the magnetic field of the machine.
This is also why large power transformers are bolted together with heavy I beams holding the structure up and laminations of the core together. Forces equivilent to the power rating of the machine are trying to push it apart
