best glue for balsa?
P-47 D PILOT,
When it comes to glue, 'best' means different things to different people. For most of the people building models, best seems to mean fastest, which is to say CA. Generally, strength of the bond is not an issue, since all of the glues we use are able to make a bond stronger than the wood. If the joints aren't as tight as they could be, you may want a glue that fills gaps better. For me, toxicity and environmental impact are worth considering, so I use aliphatic resin whenever I can ( Tite-Bond or Tite-Bond II ). Aliphatic resin is strong enough for any joint on a model airplane, including gluing the wing halves together. For parts that get direct exposure to fuel, epoxy is a better choice. For parts that are just really difficult to clamp, CA is a better choice. Otherwise, it's Tite-Bond for me.
