Clock Springs
Clock Springs
(OP)
I'm trying to make a retractable cord system using a clock spring (kind of a hobby/home project). I am looking for a pull of 10lbs and about 20' of release. I want to keep it fairly small, say under 4" diameter...so about 19 turns.?.? Can anyone help me get started with how to determine spring size (or if there is somewhere I can go that will allow me to pick the clock spring based on the parameters I described above)? I have an engineering background so I can do calcs if need be. Thanks

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Has about 20' of cord and works great!! I love it. I think it was about $25.00
Might look into that.
