I finally got a coax line through a packed wall cavity in a Denver apartment
The old plaster and lathe was blocking everything, so I tried a trick with a shop vac and a plastic bag. I taped the bag over the hole upstairs and ran the vac hose on the lower floor, which pulled the fish tape right through. Has anyone else used a vacuum to help with a tough pull?

That's a clever trick with the plastic bag to seal the hole. I've used a vacuum to pull string through conduit before, but I've never tried it through a whole wall. How much of a pressure drop did you get? I'd worry about the bag getting sucked in and blocking the path if the hole was too big.

Yeah, that bag trick is way too risky for me.
