I've had Hobbit for about a week now and I have to say that I am really digging it. Theme integration is phenomenal!
One "issue" I am having is the left ramp is not clean - it clunks around at the top and only makes it around the ramp about 75% of the time. It is almost never smooth and the ball always slows down since it clunks against the edge of the inside metal wall.
After some investigation, it appears the ball travels around the far edge of the left ramp then banks off the center/back of the assembly and into the inside wall of the right entrance (kinda hard to put into words).
Is this common on Hobbit? My right ramp is smooth as butter. The whole assembly appears to be in normal condition with no cracked weldments...
