So, after 3 weeks of trying 2-3 times a night, i finally got my first coal.

Ive gone through various types of woods, Beech (I think) dry kiln stuff and back to a better dried beech (I think)

Now, this is only the first time ive ever done this successfully, so dont take what i say as gospel, im an absolute noob, just wanting to pass on what i learned to others.

So what did i learn?

Form, i seemed to have the form straight off the bat and thought this would be easy to master, how wrong was i?

I could build up the black dust, but when i thought i was ready, i would press harder and faster but would create tiny little black curls instead of dust which would not conduct the heat as well. No matter what i read, i could not work out what was causing this, no one had a definite answer for me.

The answer was..... Pressing too hard during the end / fastest stage. (and possibly the wood)

I start of with more pressure and a pretty slow pull / drag to begin with to get smoke and build up the dust, then i actually STOP, take the spindle away carefully, catch my breath and reset.

Once ive reset position, i start off slowly to get the motion correctly, then i speed up the action, much faster than i expected too also thinking about it, but most importantly of all, less pressure.

The way i think of it, im using the same amount of energy by going faster in my stroke but by reducing the pressure, im still exerting the same energy as when i had increased pressure at the beginning phase.


THE BEARING BLOCK - OMG THE BEARING BLOCK.

This is something i refused to take on board in the first 2 weeks, i was adamant that i was going to do this with a wood bearing block until i got so disheartened i swapped for a shot glass to reduce friction. They all say this and i would not listen, so guys, please take this on board.

Anyway, its not proof unless you have pics.

I wish everyone who takes up this skill the best of luck as it was frustrating as hell for me. Something i shall be practicing on a daily basis for now with different woods etc.

If you have any questions, please feel free to ask and i shall get back to you as soon as i can.


Good luck all

Make that twice in 1 night then.

Just had another go and what I noticed was that I used less pressure in the later stages.

The biggest thing that I noticed also was, although I did the whole start to finish in 1 attempt, I noticed in the end stage where I speed up the turning of the spindle, my strokes were getting short. As soon as I started using the full length of the bow, I created more dust particles, smoke and was in effect making the drill create more heat from the longer strokes.

Something I didn't do until tonight.

Just thought that might help others incase they are having the same issue.

You'll probably find you can crack it every time now congrats! As for bearing block I have a divot bored into my knife handle. Works for me because I had the same friction problem
 
Well done.

Afterthought edit.

Pressure will grind, speed will burn, and as I recall you want it hot at the end. If you do both you end up with an almost nearly with broken string.

Congratulations. Now you need never do it again. :D
Seriously well done mate.

Thank you all, much appreciated. Managed to do it now with a wooden bearing block, so just continuing to practice with more difficult circumstances.
