Ok so I currently have an order for 0.2x1x1000mm tension springs stuck in customs for weeks and placed another order just today for the same in hopes it goes through faster. But at $9 for a single spring that is 3ft long, I am feeling RIPPED OFF on price. It is bullcrap. All relating to the tariff nonsense. So I decided today to pivot and just roll with the elastic band in place of tension spring. It's a jewelry making elastic band I bought some time ago in a roll. WAY cheaper at $0.03 for 3ft instead of $9 for 3ft. That's 99.7% off! Talk about a discount! The issue I had before when I looked into this option was the tie-off point. I would need a way to tie PE fishing line to the end of the elastic band without the tie point being bulky. Well I figured out a way to do it without any bulk at all! See I want this to fit into my 1.8mm ID PTFE tubing to keep size down. My solution was to just glue the fishing line lengthwise directly to the elastic band. No knot at all. No turns at all. Just literally lay it on top and glue it down flush. I figured about 6mm length of joint would be solid. And I did this on both sides with my PE fishing line. I used 0.08mm 6lb test braided PE fishing line for this. So now I have two fishing line segments coming off the end of it for double the strength of this connection. But I only wanted one piece of fishing line to go the distance to attach to the motor end so I twisted the pair of fishing line segments together and glued the twisted pair with 401 glue then cut one of the two away leaving just one of the pair to go the distance to the winch in place pulley that this is all supposed to tension for me.
