I've peeled back the silicone to check out the weld on the other side, and it looks good. I am a bit concerned though, if I ought to shorten the insert on the horizontal section if I might ever need to perform the same operation on the other side.
I am going to be very careful how I use her from now on so as not to over stress that area. OK, I've chosen not to cut the inset, iff the other side breaks, I'll deal with it.
