I'm working on a paper clock and I have a few questions. Have any of you used wood hardener on your models, and are you able to use elmers white glue afterwards successfully? Also, after laminating a gear with elmers white glue, and letting it dry between a flat piece of glass and a few books it came out slightly warped similar to, but not quite as bad as a pringles chip. Can any of you tell me a better way? Thank you in advance for any advice.
