Doc has a great thread on the hand drill going here.
He has some great tips below. To compliment, I made a quick video today (I'm a one take wonder). Even surprised myself how quick the coal came as it is a bit windy out.
Adding to Doc's tips...
- Use all the resources out there, many different tips/tricks, species, etc. They are all going to be helpful as everyone is different.
- Premise of the hand drill is the same as the bow drill, however, many think a little larger notch is helpful. Be consistent with the bow drill before tackling the hand drill. If for nothing else, confidence.
- Quit and give your hands two or three days of rest if you think a hot spot is becoming a blister. You will be sore at first, but the muscles in your hands will develop quickly and heal quicker than the blister.
- Having a straight spindle is critical when starting out. If using mullein, that straight part maybe under the seedhead too. Simply scrape it until it is smooth.
- While 'floating' your hands looks cool, it is not necessary.
- Use your entire hands!
- Common sense says it is easier to have the thinner part of spindle at top for more downward pressure which is true. However, mullein and other spindles can fray easily, so don't hesitate flipping it over ~ there is not that much difference.
- here are ID links to the species used in the video (note the maps):

Another tip, in case you don't already know, a straight stalk is necessary, so if it's a bit crooked, with a bit of heat, you can straighten it. Before somebody says that you won't have the heat until you start the fire, I'm talking about practise.
Couple of other things -
-when using Teasel, cut the notch in just past where the periphery of the stalk meets the hearth - this is where the char forms - more inboard is a softer part of the stalk that rubs away without contributing.
-the thicker (the hard part of) of the drill wall, the better the drill.
-the harder the hearth material, the smaller the diameter of the drill and conversely, the softer the hearth, the larger the diameter, keeping in mind the diameter must be large enough to spin the drill.
-if and when the drill starts to 'socket', stop and 'dish' out the hearth (so that the drill contacts on the bottom only, not also on the sides - this dissipates a given amount of friction over a greater area, reducing the temperature, not to mention causing more drag and contributing to muscle fatigue.
-when a hump starts to form in the middle of the hearth depression, remove it. This is counterproductive in the same way 'socketing' is.
-to gain the proper traction between the drill and your hands, spit on your hands - you want them damp, but not soaking wet. You'll see what I mean when you do it.
Well, that's a few tips, anyway. If you have any questions give me a shout. BTW, like bow drill (in my area), Basswood (T. americana) and Poplar (Populus spp.) are my favoured hearth materials for hand drill.
