is the mother of invention, as the old saying goes. Back in the 1950s, invention
was the necessity of modelers who were either on a tight budget, did not
have access to the plethora of gadgets and devices available these days,
or both. I really enjoy reading about some of the ideas devised by modelers
for use on their airplanes. While doing something like splitting balsa sticks
lengthwise to facilitate bending around tight curves - similar to laminating
individual pieces, but on a local level - might seems obvious to a seasoned
builder, there are always new people entering the realm or even old hands
exploring a new area of aeromodeling who need to learn new methods. I actually
had an idea printed once in Model Aviation where I suggested saving the
small hypodermic dispensers (the ones with the skinny nozzles) from tooth
whitening applicators for use in injecting epoxy into hinge slots.
