Originally I had put "We make ourselves a bell at the church." That was marked wrong, and the answer given was "We make ourselves a bell to the church", which simply doesn't make sense, grammatically or otherwise.
Then I clicked on the Discussion link, and the answer given is "We make ourselves a bell for the church." This is a nonsensical construction: if we're making OURSELVES a bell, it's for US, it can't be for the church. It's not completely impossible to rationalize this construction... but it would require some serious stretching of the definition of 'normal' speech.
Wow! DIY bronze founding! Maybe that is why the 'ourselves' is emphasised. I've seen new churches bring built in Romania, but is it really the case that a village would cast its own bell? Fascinated to know. I'd love to get involved in that.
