Hey, that's neat!
I remember the first time I made fire with two sticks. It was on Christopher Nyerges's survival day outing in the mountains near LA about 11 years ago. I wonder if he still does those. He was teaching how two people can accomplish fire by hand drill and I decided to try it on my own since I was the only one who came without a partner. Walla! It works. I was so stoked. The other guys marveled because they couldn't do it. "WOW! How'd you do that?!" I could see they had their rhythm wrong, as during the second they kept losing each time they switched back and forth allowed a loss of momentum. They couldn't really work together in a fast steady flow, but one of the guys succeeded when he tried it on his own.
Chris made it easier because he had the ideal fine-tuned wood pieces.
I had tried unsuccessfully to make fire with a bow drill a few times over the previous years, having read "Tom Brown Jr.'s Wilderness Survival Guide" in the 7th grade, but I could never get a handhold piece that worked for me.
After Chris taught us how to make cordage with Yucca leaves I made a thick cord and tried again, using a plastic soda top as a handhold, which was working until the shaft drilled through the soda top. I switched to an abalone shell handhold, and WALLA! I made fire; with a cedar baseboard, a false-willow shaft, Yucca leaf string, and an Abalone shell! Dried Mugwort leaves are a great tinder.
