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.

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.
