I've never had the weight hit anything. I only have 400 ipm rapids and a standard 20" z though.
On some big machine with extended z moving 700ipm I could see how that thing might get swinging.
An easy way to dampen the swing would be to put a container of water attached to the top of the weight, say 2-3 gallons in a tupperware (half full to allow the water to slosh back and forth opposite to the swing of the weight) container zip tie it to the chain. Super cheap, and I bet it would stop the swinging. Maybe use a capful of bleach in the water to make sure it would not rot. |
