I enjoyed your Expert Answer (p. 66) in the Feb/Mar issue and wanted to share how I hung my air filtration system in my basement shop. Instead of chain, I used hobby horse extension springs that did away with any vibration up the floor joints into the kitchen. They cost only $4 apiece, so it’s not an expensive alternative to chain. Plus it’s well worth it to not be blamed for the collapsed bread in the oven.
