The Work Bench is a resource for R/C modelers seeking building info---FAQs, tips, hints, techniques, and special or unique tools and building materials.

• The technique of vacuum bagging is used to construct foam core wings, either with a wet layup of fiberglass cloth and resin, or to apply a wood veneer skin. Both practices use the same principal: enclose the wing in an airtight "bag", then remove the air inside the bag allowing atmospheric pressure to hold the wing skin against the core while the adhesive cures.

• "Knuckle" hinging. OK. You've just finished 'bagging a new set of wings. You've trimmed the edges, applied the leading edge, and now you're ready to hinge the surfaces. Nothing says you have to do anything special when hinging a 'bagged wing, however, a vacuum bagged wing is an ideal candidate for a tubular "knuckle" hinge..
