If any think they can help me please please write here so i can send some photos of how it looks right now!

    It is hard to know without more pics or anything, and I haven't taken apart a Soligor lens.

    But I do know that many lenses are designed so that this happens. The idea is that you loosen some screws, and calibrate the lens by focusing it to infinity (by using a distant object). Once the lens is focused you set the loose focus ring to infinity and tighten the screws to lock it down.

    the screw in the circle was the one which came loose.

    So the main problem im finding after sitting most of the night figuring out the lens is those two bronze colored sticks that you see in the first picture, they sit super close to the threads and they do not rotate, only the threads do when focusing. I origianly thought i could just screw on the optical part but is not happening becuse of those bronze things.

    I think that these bronze things are guides stabilizing the helicoid. There are suitable places for them in the front piece. The helicoid will screw in in several positions but only one of them is correct one, the front piece has got 3 starts showing so I think that there is something like 8 possible starting positions.

    on the 4th picture you can see two holes on each side of the optical part, those fit in the bronze part but i cant screw it in. The threads seem either very thight or just really hard to aline.

    They are hard to line up. Usually there is quite a bit of play in helicoids and helicoid grease is used to take care of fitting them together but they must be exactly on same line and the helicoids will start to screw in in many positions. When dismantling helicoids you usually mark where you start to screw with a felt tip pen.

    I broke and fixed it at the same time. It now work to focus but the aperture is stuck wide open. that's is were i always shoot so not does not matter to be but the re-sale value is now second to none.

    There is usually a lever that forces the lens wide open, so that the film camera it was designed for would have a bright viewfinder for composing.

    When taking a photo this lever is released and the lens stops down for the correct exposure.

    This is most likely causing your issue with the aperture, but maybe try fixing it after your wedding shoot.
