I am building the 90' now and have found that you need to add as much weight as you can to the bridge. Next when you add the decking you need to make sure it is centered on the locating pins as there is a lot of slop. On the pic that shows the bottom of the turntable it is missing the giant gear that locks the bridge in place, without it it will tip. As far as being out of round, mine seams pretty near perfect. Last you are correct in the way they say to power it with the screws holding the wires just dose not work, I kept the brass wipes but soldered wires to them, will have to see if there is a problem long term though. For those that have not started theirs I can not emphasize enough that you have to test fit the bridge and adjust the bogies so that they rest on the molded in rails when the bridge is properly seated, if not you will have some of the problems described like tilt when the engine goes on and off.
