counterweights anything based on springs/elastic is going to provide the least force when there is more slack chain, which is when the most force is needed. a weight based system provides a constant amount of force, which can be changed easily. I would suggest using 2L soda bottles or similar for the weights so that we can adjust the weight by changing how much water is in them (and they, or milk cartons, or similar containers should be essentially free for everyone. The lines between the chain and the weight need to be guided around the top beam. Can this be done with eyelets? or do we actually need the lower friction of a pully? --- _[View the full topic](https://forums.maslowcnc.com/t/improved-chain-tensioning-for-top-beam-configuration/3284)._
