Doc, of course! I'd never let you down. And when i am not practicing, I'm thinking about it!
Actually, I was cutting firewood yesterday, and grabbed some fine looking pieces for another bow, drill and hearth. The poplar wood is working out quite well as the hearth, it has a fairly low ignition temperature, and, as long as it's not green it tends to be quite dry. It's weight and density is along the lines of cedar.
I'm getting a good ember about 75% of the time on the first try.
After that, it's all about the tinder. Which hasn't been a real challenge as we have been in a summer-long drought.
I'm more concerned with being able to do it, with an acceptable % rate of success, under less-than-ideal conditions.
