Hey guys, ive finished making a spear gun, and i need to put a line release in. I cant attach it to the mechanism as ive already made that, but i need something thats going to let the line go. ive seen these things around (click on the link), but i dont really understand how they work, like do they just release the line because of the pull of the line, and do you just drill a hole and put the pole in and attach the line release? any ideas as to how i could add a line release would be helpful.
