comment Replacing rubber connection in a bicycle trailer coupling
Its a good idea using a car tyre. I got it myself after posting ;) I googled a bit and apparently its quite easy to cut the "side" of the tyre with a sharp knife, and I think 2-4 layered together would be strong enough. The part of the tyre facing the road surface is cast with a steel mesh inside. This makes it super strong and ideal for the purpose. But its quite difficult to cut, and with my tools probably not viable.

comment Replacing rubber connection in a bicycle trailer coupling
Good question. I believe its not reliable because when I twist it the cracks seem deep and it is simply too flexible. I believe I can break it off in a few seconds with my hands if I want to.

I found it in a scrap container. There is only the frame and the wheels left. No box. And no name or model or nothing. I think I remember seeing this kind of coupling before, on other bikes, I thought it was sort of generic.

comment Removing Seat Post rusted into downtube
Another issue with the inside flooding approach is that I would need to spray enough WD40 (or ammonium or whatever I am using) into the frame to know that the seatpost is completely full and the agent is up and above the point where the seatpost ends. I guess that could be quite a lot of WD40. When turning the bike back I would need to carefully pour the substance into a carton or smth and discard it in a environmentally safe way. Just spraying the upper part will not require much spray. But of course, maybe the inside-attack is more likely to succeed.

@Chris: Flooding the inside only lets it work from one end. Obviously it is possible to attack from both ends, but flooding the inside only works from one end. Don't you agree?

comment How to remove completely stuck saddle post from frame
@jimirings: While I generally agree with the StackExchange concept of weeding the content to ensure high quality and make it easier to navigate, I often find myself in a situations where contributing with my info/experience just requires too much work, and right now is one of those cases :( Adding a new question with answer seems/feels very constructed and forced, but I will try.

comment Removing Seat Post rusted into downtube
Remember that if you cut of the part of the post which is outside the frame, and then fail in removing the rest with a hacksaw blade, then you are pretty stuck, and I don't see any solution but to discard the entire frame.
