I made my first ember last night using my bow drill set and I'm dead chuffed with myself 
I have made fire once before with this method when I was first shown how to do it, but that was with someone els's kit which was well used, and I didn't know the details of exactly how it works and how important it is to have good technique and a well sorted set. I read everything I could find from various sources, but I still had to learn from my mistakes when doing it for real, which is of course the best way.
That said, if you are a complete beginner to this method, hopefully these tips will help save you time, effort and frustration. I need to do it again tonight to prove it wasn't a fluke!
1. When you "burn in" the set, make sure that the hearth hole is deep enough to help support the drill when you use it in anger. If you don't you will get mightily fed up with the drill repeatedly falling off the hearth! Also make sure you burn it in long enough to produce a perfect fit between drill and hearth; any gaps or uneven edges waste your effort and reduce the effiiciency of the set.
2. Likewise for the bearing block, make sure the hole is deep enough to locate the top of the drill for the same reason.
3. Every time you use the set, lubricate the bearing block with green vegetation (I used wet grass) to make sure that all the friction (and therefore the heat) is generated where you want it in the hearth instead of the bearing block.
4. Get your body position right; I had my head right over the top of the drill, looking straight down at the hearth. This helps maintain vertical pressure on the drill in a dead straight line and again gives maximum efficiency for your effort.
5. Make sure that you bow horizontally, using the full length to begin with; any slight deviation leads to the cord "creeping" up or down the drill and ultimately forces you to stop.
6. Make sure that the cord is tight enough to grip the drill properly; having it slip when you are working hard is another waste of your effort.
7. What worked for me was "fairly slow with enough pressure to produce black powder and wispy smoke", followed by "flat out until your arm falls off".
I have to say that the satisfaction I got from kneeling on my garage floor in the cold, gently fanning that ember into a glowing coal was immense. This is about as perfect a learning experience as you can get.............
