I used the cheapest spray foam from the home depot I could find. Normally they mention the expansion ratio, but these don't. I used 2.5 cans of 500ml. So between 1 liter and 1.5. If you can find the expansion ratio of your foam. Theoratically you could measure how much you will need. But I have not done that. If you measure to cylindrical content of the sleeve. I use the average of the smaller cylinder and bigger one, which is around 104 liter. This would mean that if I would have used a foam which would expands 1:11. I would only have needed 1 liter. I am not sure if this holds up though, more experimentation should be needed in order to give you a thorough answer to this one :-).

Thank you for the feedback. Nice to see that this piece brought up so many emotions with you. Good tips as well, regarding the farming, steel milling and coal mining culture. Whenever I visit America, I am definitely going to dive into this part of the culture. Thanks!
In the back I have put a pillow, cause it stings a bit. But I'm pretty sure that after a while, the fibers will become a more flexibe.
