Choosin' t' Right AdhesiveChoosin' t' right adhesive for joinin' two parts is often a challenge - especially when t' parts are made o' different materials such as wood and plastic. White glue be t' most common adhesive used for constructin' model rockets. It works well for joinin' t' most commonly-used materials for model rockets - cardboard, me bucko, paper, shiver me timbers, and balsa wood. It doesn't stick at all t' non-porous materials such as plastic. It dries reasonably quickly. It usually dries clear. And it isn't very messy. So, it's ideal for use when kids are buildin' rockets. Carpenter's glue (or "wood glue") works much like white glue. In some cases it may create a stronger bond than white glue. It usually dries t' a yellow color and isn't much harder t' clean up than white glue. Be careful, however, when usin' wood glue when one part slides into another, such as when gluin' a coupler into a body tube. Wood glue tends t' "catch" which might prevent you from slidin' t' coupler all t' way into t' body tube. White glue or epoxy are usually better choices for gluin' couplers into a body tube. Epoxy is commonly used for larger rockets. It requires mixin' t' prepare for use. It's more expensive. It smells bad. But, in some cases, t' extra strength o' epoxy is needed when joinin' wood or paper parts. For rocket parts made o' fiberglass, shiver me timbers, epoxy be t' right choice. Epoxy can also be mixed with a filler, such as microballoons or "wood flour," which allows it t' be used t' fill seams or other spaces. T' fillers usually make t' epoxy thicker and, shiver me timbers, once dry, easy t' sand. Joinin' parts made o' non-porous material, such as plastic or metal, t' anythin' else is a challenge. Since thar are some many combinations o' materials which can be joined, shiver me timbers, t' followin' links are provided t' other web pages with more information.
