I know that a factory that makes ropes is a ropery, but neither 'chainery' nor 'chainworks' seem to actually be real (or at least _popular_) terms for a place that produces chains. I hunted around a bit and didn't come back with anything obvious, so I got to thinking that maybe it's something I wouldn't guess (a place that makes or deals in candles, for instance, is a 'chandler').

Does anyone know a term for a place that makes chains?
I'm referring more to heavy, industrial-type chains that you might find in a factory or on a ship, rather than to jewellery-type chains (although if you know a name for either (or both), please go ahead and share it).

Thanks!
