Im very confused, you say the cylinder should at least be 1 cubic meter/40 cubic foot but when I calculate the sizes of cylinders in my area that looks to be about as big as the one you have since our supplier gives a size chart with size labelled and I compared against your picture with the chair, I get results like 1 cubic foot for a cylinder that's 32.9" tall, and 7.25" in diameter (length and width)
Wouldnt a 1 cubic meter cylinder be ginormous??? Was there an error in the unit labelling in the post or am i not doing the math right? Im using this calculator
Cubic Feet Calculator helps to calculate the volume of a box or space. It also helps to calculate cubic feet from inches, feet, cm, m and yards to cubic ft^3.

I could easily bs my way out of getting a cylinder the size mentionned above as an excuse for electronics soldering works, anything much larger would be suspicious... And I certainly dont have that kind of space
