I am building a chest with a multiplex lid of about 100x40cm, 10mm thick, weighing roughly 5kg. I am trying to find a combination of hinges and dampers so that...
- When I open the chest, the lid must stay open in the vertical position (it must not be necessary to hold it).
- When closing, the lid must come down softly. Even if I just nudge it a bit in vertical (or someone accidently knocks it), and it has all of its kinetic energy available, it must go down slowly - especially at the end, when it's about to hit the chest.
- I do *not* need to keep it open in any arbitrary position; only fully opened or fully closed.
I am free to use any part of the chest to add any fixture that makes sense - i.e., the back, or the side walls.
I have looked at what's offered for things like that, and I found a few items... simple hinges (the type used for cupboards), gas struts (e.g., pneumatic cylinders), and plenty of different kinds of articulated dampening soft close hinges. Unfortunately, I have no intuition which might be the correct/best type to use. I would like to avoid wasting ressources by buying whatever, and trying to find out it's the wrong thing.
Can you suggest anything?
