I was at a local Christian thrift store a while back and spotted a used standard iron weight set for a good deal so I took it. Half the plates were New York Barbell and half were Weider. The 25 lb York plates' holes are too big for the standard iron bar, but too small for Olympic bars. Strange... Here's the really strange thing, though. It was a two piece barb that was kinda riveted together and then welded (its so tight and solid it had to be). Even though it seems to be kinda solid and all, I've seen those cheap kiddy cement weight sets sold at Wally World and they aren't even riveted or welded or anything. They go together in the middle with allen screws. That seems kinda dangerous to me....does it to you? Anyway.....I'm not using this bar for anything but the lighter stuff like curls and stuff but I still wanted to get some opinions on whether you've seen this type of thing and whether its safe. I asked a guy at the local Play It Again Sports store and he said he'd never heard of such a thing.....and he seems to be pretty in the know.
