The broken casting for the fence base happened to a few I know as well. In my case, the fit of the base was a little sloppy, which made the fence "swing" into position. The work-around was to push against the fence before tightening down. But this should have beeen unnecessary.
For all of us (with an issue), Felder (in Perth) was prompt in replacing the part.
I compared the parts, and the original had a thinner casting. The fact that it is a casting, which may have hidden occlusions, places it at risk. Having said all this, my replacement is about 15 years old now.
