Sketchbook - Model Building Tips
March 1955 Air Trails Hobbies for Young Men
Necessity 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.
