My son had his first Pinewood Derby over the weekend. We started out by having the all of the kids in his den over to the shop for a "meeting" where we started working on the cars. Of the 6 kids, i'm the only parent that has a shop, much less a work bench or basic hand tools.
I was a bit curious to see how it would go - a bunch of 8 year olds confined to a space with a million ways to hurt themselves for an hour and a half. But, after they got the shapes of their cars sketched out on their blocks of wood, we gathered around the band saw to show them how it works, discuss focus and proper use, and instill the fear of amputation firmly in their heads.
Each kid roughed out the shape of his car on the band saw. My son was the only one who had used a power tool before. It definitely held their interest. Some took the cars home and slapped some paint on them for the race. My kid worked on his every night for a week and a half.
Race day came, and everyone had fun. I did have to smirk a bit as another parent was criticizing me for building my son's car for him. If only she had known the facts. I didn't say much, but did have to remind her that i helped her son cut his car out on the band saw just a couple of weeks prior. I helped my son with instruction and a touch of filing, but 95% of the effort was his and his alone - including the 5 coats of spray paint that turned out smooth as glass.
Through the process, my kid used the band saw for the first time, learned how to use a rasp, did a lot of sanding, and learned to spray paint. I think that was a pretty good effort. To him, though, it was no effort at all. He was pretty absorbed in the process for two weeks.
