{Here comes my howto build a flatbow}
From Craig (thanks for that!) I got the allowance to cut down an elm tree wich died in a drought 2 years ago.
Therefore I started not with a wooden board - with a small stem instead.
I started used a chisel to drift into the thick end.
The resulting gap I enlarged with a small hammer head as second wedge.
Now I have to split this in quarters.
Always simple following the appearing gap.
Choose one wich is not too twisted.
Shape it with the drawing knife.
This wedge (under the clamp) helps to hold the stave in place.
To flatten the sides I used two different planes.
On the left the heartwood, right is the sapwood.
Yes the stave is not dead straight - but who cares...
Drawing a few lines for the tapered ends.
Filing the gaps for the string.
The stave is ready for tuning.
When you lay down the bow in front of you it's easy to see where the bow needs improvement.
Fine tuning with block plane and scrapers.
Smoothing the surface with a hand scraper, build from a old hacksaw blade.
Test with the real string - looks good.
10 layers cardboard, distance 10 meter :)
It tooks me circa 1 hour to split the log
please email me if anything is missing
Unfortunately my two bows wich I brought from Germany are broken.
Therefore I had to build a new one.
In theories the outer side from a bow (away from you) gets stretched; the inner side get pressed.
That means for a well working bow you need the two properties of wood:
sapwood will bend well, heartwood is strong under pressure.

Taper the end with a plane.



tuning (the German bowmakers use the word: tillern)
carefully remove heartwood to archive a consistent bending.
In the picture below you see the red spot where the stave needs weakening.
The tillerboard is just a meter long piece of wood with serrations
every 5 cm and a rounded gap on one end.
It is used with a temporary string.
First try - not to bad isn't?





and 6 hours to build the bow.
Have fun and take care!
Viel Erfolg beim Bauen!
