Hi, John,
I'm with you! <VBG> I had a heck of a time with that one..... even 'with' the WT!
You're trying to put all 4 pieces together to get one huge machine. You only have to worry about moving 3 of them. The one at the top right stays put. You use the panel on that console to direct each piece into a position that will fit the one just before it, then it slides into place. Then do the same with the others. George will tell you when you try to move it if you've got it right. It's much easier than it seems. The clockwise arrow moves the energy flow from one direction to another to enable you to use it to move the machine. The counterclockwise arrow rotates the machine piece until you get it to fit into the one before it. Phew!
Good question! Hope this helps a little at least!
