i'd like to hear about folk's experience (particularly the successes--coals attained) using bone, ivory, antler, rock, fungus, shell, and other non-wood materials as spindles or hearthboards with hand drill, bow drill, fire saw, fire thong (anyone use leather for the strap?) and fire plow.
i've got a couple friends who, along with myself, have gotten embers using wooden spindles on bone hearthboards (bow drill). i've also gotten a bow drill ember on a rock hearthboard. and it's not difficult to use a wooden spindle and get embers with bow drill and hand drill on polypore fungi hearthboards. anyone else had similar experiences?
