A couple of day ago I heard a big bang while cooking. I looked all over for cracks and other mayhem, but did not find anything. Today I found it. The plate holding the left spring on the XL had come apart. I found all the hardware, and put it back together. I checked all the bolts on both the XL and the LBGE and found many that would take some tightening.
XLBGE X 2, LBGE (gave this one to my daughter), MBGE and lots of toys
