Removable glue for LEGO models
I would say low temp hot glue. I have done this for several my son really wanted to "keep". I figure one day he will be able to take it apart but it saves it from dropping and such!

How to open first version of the pneumatic cylinder? (Part no 4688c01)
The original glue was solvent based. This means that both sides of the joint are more or less fused/welded together. It is not a simple case of "2 pieces with glue in between".

I have had success with super glue (LocTite). I recommend it because:

Gluing small parts with hairspray?
AFAIK those "bead glues" work on a completely different principle where the sheen on the individual beads is a water-activated glue and so the finished piece needs to be sprayed with just clean water ...

How to open first version of the pneumatic cylinder? (Part no 4688c01)
It might be hard or impossible to fix this so I'd rather address how to fix the issue of having non-functional element instead. You can look into acquiring a used version of the same LEGO item from ...

You could perhaps try hot glue in some old test parts and after a few days, use rubbing alcohol to remove the joining power of the glue.

What's the best way to glue/adhese the street baseplates to a plywood table?
I used spray-on contact cement (the kind where you spray both surfaces, wait for them to get tacky, and then press together).
