Ok. I've investigated thoroughly.
The three holey things are definitely holding the three pronged thing on. The spindly thing in the middle is fixed solidly to the 3 prong thing and is not attached to the drum at all (I can put something underneath it and out the other side).
The only way I'm getting off the 3 pronged thing is with a very large drill bit. It's gonna cost me a fortune to get a drill that can handle a drill that works on metal and is that large.
So I reckon the brick idea is the way to go Or something like that. A stand of some kind?
Or, I could potentially get a hack saw and chop it off. But I have this little issue with metal on metal.... *shudders*
