Would take me what felt like hours to wind it all back onto the spool. Standing there with binoculars and even then it was the tiniest faint dot and took lots of hunting in the sky to find it. I’d go out to a church parking lot with my spool and take the kite out till the end of the spool. The quantity of string was pretty ridiculous, I used one of my Father’s spent welding wire spools to wind it all up on. Today, I realize that it was flawed math as I didn’t account for sag/stretch, etc. Genuinely don’t know if I got what little math I knew right back then. Used what little I knew about geometry to estimate how long the string would be based on the angle of the string hanging from the kite when it was in the air. So she indulged my outlandish goal and kept buying me string. Eventually my Mother asked, “What are you doing with all this string?” and confessed my intention: “I want to fly my kite 1 mile high”. Each shopping trip, I’d ask for more string. That made it a bit better… but wanted to go higher. That would not do! So next time I was out shopping with my Mother I asked if I could have some kite string. Well the paltry amount of string that came with it would barely get it over the top of our house. As a boy I bought some blue delta kite and flew it in the backyard.

Personally, we’d have included a counter to keep track of how much line is fed out something like this printer filament counter might work, as long as you can keep the sand out of it. We really liked the research that went into the self-reversing screw used to evenly wind the string across the spool who knew that someone could do a doctoral dissertation on yarn-winding? Check out the “Reeler-Inner” in action in the first, much shorter video below. With that information and a cardboard prototype in hand, the guts of a cordless drill joined a bunch of 3D-printed parts to form the running gear. Basic questions had to be answered, such as how much torque would be needed to reel in the kite, and what were the dimensions of a standard kite string reel. Of course what’s simple in conception is often difficult to execute, and as the second video below shows, went through an extensive design and prototype phase before starting to create parts. If you’re like, the answer is simple: build a motorized kite reel to bring it back in painlessly. Eventually it has to come down, and the process of reeling all that line that was so easily paid out is likely a bigger chore than you care to face. So you’ve built a fine kite, taken it to the beach, and let it ride the wind aloft on a spool of line.
