I am in the process of building my first gate assist. I am going to start out with just one spring. I have purchased a spring from Lowes. 2" sheaves from TSC and six feet of cable and some chain to adjust the tension. I plan to purchase something to inclose the spring. Other than this what all things am I missing. I assume that I only need one eyebolt to attach to the gate. What size bolts should I use to mount the spring to the frame of the trailer? I am also not sure exactly where the cable attaches to the spring because i can not see it in the pics because the spring is covered. I assume that it is attached the the end of the spring the same as the bolt. Thanks for any help on this. I want to do it the right way and the say way so any advice is appreciated. This forum has been a great help..
