The Klondike Derby is an annual winter camping trip held in our district (and many others across the country) for Scouts to hone their scouting skills in a winter environment. During the weekend event, Scout patrols go from station to station around our local Scout Camp, facing challenges that require them to demonstrate their skills in making a fire, navigating with a map and compass, cooking, knot-tying, and applying first aid. The Scouts must bring all their gear with them as they trek from station to station, including ropes, stoves, kindling, and hiking staves. Hence, each patrol is required to have a sled for their gear which they, as a patrol, must haul. The sled must be strong and stiff to hold the patrol gear, yet lightweight because at the end of the weekend there is a race between patrols, and the fastest sled wins.

I’ve been experimenting with approaches to building a variety of composite tubes. Following are some things I’ve tried (some that worked and some that did not) that you may find of value if you want to produce composite tubes yourself. Continue reading →
