The House Of Balsa Dust / Handy wing support during construction.

If you're building large models, supporting the wings during construction can be a fiddle.
A few years back I snagged a pair of cheap photographic tripods from KEH Camera Brokers for something like 10 bucks each.
I've made a couple of different "adapters" to fit the camera mount (1/4-20 bolt) to deal with various problems. One set of "adapters" are shown here - 1/4" oak stock drilled and tapped to fit the camera mount bolt, with a chunk of foam glued to the top of the board. Makes for a pretty good "jack stand" to support the wings on large models. The cheap tripods are a _lot_ stronger than they look; I've tested them to 35 pounds load and they're steady even at that weight. Once the model is finished, I build model-specific wing supports for use during set-up at the field.
