I had this cardboard clock set once when I was 10, I remember giving up on it because you had to glue 7-8 layers of cardboard to make the gears, and the gears would warp badly because of the glue. I found the kit again cheap and ready to give it another go.
So my question is how can I make sure the cardboard wont warp? just thin layers of glue?

Cover the cardboard in a few layers of acrylic gesso, found at any craft store. Let it dry between coats, and once you add a few coats the cardboard should be fairly moisture resistant.

use a non-shrinking, waterless glue. something like pritt stick, or maybe double sided tape.

Can i still glue to it once the gesso is on there?
for what its worth, this is the official supplies list, which suggests liquid glue and optionally liquid lacquer

don't use too much glue
put it under a heavy book (the things we used to have before computers)
but mostly you will be using too much glue
