In fact, if you can saw a penciled line, apply glue, drive nails, and bring a modest measure of patience to the task, you can build and launch a smart and able craft in as few as 40 work hours. You need not be driven by lack of tools, materials, skills, or time to abandon in frustration a project you conceived in a spirit of pleasurable anticipation.
