No no no... a waste of a perfectly good angle grinder - those bearings will be shot from all that force. And - you hands will take a beating, there isn't enough mass in the grinder and additions to dampen the load.

Those two bust up examples we a joke. On the first, all the easy parts (the thin edges) came apart easy enough, but the other bits didn't work so well. The second - a couple of wacks with a small sledge hammer would have taken that one out.
