Has anyone else had the upper wheel shaft/hinge break on their BS1400 or 14002? I was in the process of balancing the wheels and upon putting the blade back on I heard a bang as I tensioned the blade. I know, it was my own fault, but is this a common problem? I see eReplacement parts has a replacement for $19.50, but it isn't going to be any stonger than the original. It's made out of cheap pot metal and the design is weak. Is anyone making a better replacement part?
