    I don't think the spike will be able to rotate the pin far enough to allow you to insert the spike through the other side of the hole due to the cramped
    quarters.

    ... Not saying that your tool won't make it easier but how often do you take it off???
    Which was the whole point in making it. We took it off last night after sailing for a couple hours. Dorian may drop in for a visit and he didn't want
    the wind whipping it.

        Fair enough
        The shortest distance between two points is a circle of infinite diameter.

          Nice job. Couple comments, spring loaded of any kind is going to corrode and jam, screw pins are universally used at sea. Marlinspike often used & bent, that’s not what they are made for, long point to open wire strands it’s not twist strong. Standard tool deck crew big ship small boat adjustable wrench with a lanyard. Tight spot like hatch dogs, purpose built wrench. Same idea as your tool.

          I would add a lanyard loop it will pay off.

            Sorry to say but it's like some of you didn't even look at the picture in the first post. Or did and only saw the shackle. and not how it's nestled into the side of the furling unit.
            I did look at the first post and to my eye, it looks like it's a pita to access the screw regardless of what tool you use. The twisted shackle I linked to could have been left in place and raised the original shackle up where it would be easy to do and undo.

              First, I want to say nice work on the tool. But I am curious about when the screw pin is installed, is it tightened with a tool? If not, what keeps it from coming loose?

                On any commercial vessel the pin is seized with wire to keep it from unscrewing. That’s why the pin has a eye. Not so often on yachts.

                  Yes, the pin is tightened with the tool.

                  ... If not, what keeps it from coming loose?
                  When tightened, the flat part of the pin seems to have some wedging action with the through hole and the short threaded end bottoms out.

                    Naval vessels do too, to a fault. It is referred to as "mousing" it.

                      Was helping a friend move a mill he bought off Craig’s list. Seller said he could lift & we roll my trailer under. Guy had a bucket on the front of his farm tractor. Hooking my straps to his chain with his open hook.

                      Said “wait let me mouse that hook”. Guy thought I was nuts. Avoid sailor talk around people that can’t speak the language .

                        Whitout the tool, an Allen wrench that fits the hole should work..

                          My design would be: short length of flat that fits up alongside flat part of eye, pin protrudes from that into the eye. Then a plastic tube slides down the flat over the pin and eye holding it in place. Tube is spring loaded to hold it in position. Metal content is far less than metal so it floats.
                          Ships chandlers just love expensive stainless winch handles 'cos they are guaranteed repeat sales on a regular basis.

                              Which is why "A" division was always called in to free up and replace buggered bolts and nuts!

                              When I was lead Petty Officer in the boat shop on our ship I tossed every adjustable wrench I could find over the side.
                              Imagine having an emergency in engineering spaces only to find buggered fasteners.
