I'm trying to find a thread that has good fatigue resistance and strength for a telescoping lift. The lift will lift a weight of around 2-3 kg. I do not intend to spool it as I read that thread with good fatigue resistance are usually not good for spooling, although if there is a kind of thread that is also good with spooling then please let me know. I also want the thread to be relatively lightweight, although that is not a big priority.
I have been looking at steel thread wires but I was wondering if there are any alternatives. Thanks!
