His son said on the special that the previous owners of the house told them to never go in the back to try and fix anything with the pin setters, as it was dangerous and potentially deadly. A few minutes later the Cake Boss is talking about how he had been back there so many times and never had a problem, and just looked away this one time. Hindsight is 20/20, but if they had simply cut the power like you should always do when messing with equipment like this, it probably would not have happened.
I will never be able to afford having my own pair of lanes, but I wonder how people with home lanes get pinsetter issues fixed (pileups, sweep down, etc.)? How do they oil the lanes? Certainly they don't have lane mechanics on staff, but at the same time what is the typical response time (days or weeks) for someone to come out and fix issues? So many questions...
