The backing plate does not really help, as there are reinforcement
inserts in the top where the bolts go through, but not in the broader
area under the handle.


So a backing plate that distributes the load over an area that is
around ten times greater than the area under the original handle does
not really help. That's a pretty interesting conclusion, Dave. I'm
glad you have this all sorted out for them now.
