Let's Commit To Something Else

After another tiresome evening of work, Mike and I have come to the conclusion that the fire bow is an unfeasible method of making fire. After making and then breaking several more bows, we decided to try to prove the concept of our efforts. We found a bit of wood that was the same type as our spindle stick. After a brief bit of work I was able to fit it into a 3/8" electric drill and smooth it out. We tried using two different base boards - neither produced a serviceable coal.

We did yield our first invention in the process though - we have grown relatively proficient at making rope out of plant stuff. We have a lot of projects upcoming that require the use of twine. We will be using commercially made sisal as a substitute to our home-made goods.

Our next course of action is to build a fire piston. This is a traditional fire-building tool used by Pacific islanders. More on that project as we get there.

Fire HARD!

Once again we attempted fire. Inventing fire is hard. Really hard.

It's not that I expected it to be easy, hundreds of former military guys make lots of money telling accountants, and weekend warriors how to make fire from twigs, sticks, and magnifying glass lenses in outdoorsy experience camps and survival seminars. Even their demonstrations don't work out well sometimes, and they have the luxury of modern fire starting equipment.

Still, I had thought that two resourceful guys with plenty of internets behind them would surely sort out a fire bow or some kind of flint spark by now. If Unk'nuk could figure it out thousands of years ago just by messing around with sticks, you'd think two fairly handy people who already know what to do could execute such a seemingly simple task. Right now our only major accomplishment is the creation of Gross-Rope: the rope that's covered in gross.

We did get much closer. Mark fashioned a much more solid and smooth stick using some stone tools, we put way more curve in our bow and just started producing smoke when our old dried bark string let go. The rest of our time was spent making a new string and trying various other bows. The challenge now seems to be in getting the proportions right for keeping the string in good tension without compromising the bow. I have high hopes that we will see some success soon, but if we don't were going to have to hit the store and get us some flint I think. Until we make fire there isn't much we can do.

Until then we are just following in the shambling footsteps of Unk'nuk.

First Try At Fire


Yesterday Mike and I got together as a team for the first time. Our objective was to build a fire. We took thin strips of bark from young branches of the basswood tree and weaved them into a rope. We weaved 3 strips together into twine, then 3 twines together into the cord for the fire bow. We found a stick to use as the spindle, a flattish bit of wood for the base, and a rock for the top of the spindle. We then made a little fire bundle out of dried bits of bark and dead leaves.


We were not successful in creating fire. Our problems centered around the spindle stick. The first was too thin and snapped. The second was too brittle and snapped. For the third we used a green stick, it frayed at the end and didn't do much to produce heat. The fourth was not straight enough and was difficult to spin.

The spindle and base got hot a few times, we're on the right track but we haven't succeeded yet. Saturday we'll give it another go.

The First Tool



Mike Z and I had an instant message exchange the other day and outlined the early tasks we want to get done for the challenge. He is coming to my house in a little over an hour. Impatience got the best of me and I built this saw today.
I started with a deer skull I found out in some hunting grounds a few months ago. I smashed it on a rock to split it in half. I then used the tooth section of half-skull to saw through a small branch on one of my basswood trees. I stripped the bark off and braided it to use as twine. I cut a slightly larger branch for the handle. I used the braided bark twine to bind the tooth section to the handle. I tested it out - it was bound pretty tight but it had some up-and-down movement. I used some more strips of bark to loop over the top and secure it better.

The cutting stroke is too wide to saw directly through branches, but you can make a good wedge-shaped score around a branch and then snap it off. I feel like a cave-man when I hold it.

When Mike comes over we'll make the other half into another saw, along with some other small bone tools.

Starting Date & First Team

I would like to have 3 teams at the beginning of this challenge. I am not planning to wait forever though - if by Sunday, August 29th there are not 3 teams the challenge will begin anyways. Teams are welcome to join any time after the start date.

Don't be shy, all you peoples out there! You don't need to be from our area to join, or have any previous tool or machine building experience. Post a comment or send an email and join up today!

Mike Z has contacted me and asked me to team up. I agreed, so team one is set! Think you can compete? I dare ya...
