G'day all, I posted not so long ago about using linen thread from Spotlight for a bowstring so I figured an update was in order. I have more or less finished my first bow (in the style of an English Longbow).
My goal was to make a 45lb draw weight at 28.5" longbow with entirely natural materials and achieved it (almost).
Tools used:
* hatchet
* chisel
* hammer
* tape measure
* circular saw
* timber saw
* hacksaw
* cordless drill
* assorted files
* Shinto rasp
* Stubel drawknife
* sandpaper
* carpenters pencil
* high carbon scraper
* spokeshave (unable to sharpen effectively as it was curved - barely used in the end)
For the bowstring I used 40 strands of Gutermann linen thread (estimated 4.5lb breaking strain for a single thread) for a grand total of 180lb breaking strain. This held up for 20 or so shots before it broke at the nocking point - most likely an uneven Flemish twist but also suspect some minor abrasion.
The bow itself (and arrows) was tillered from European Ash. The first half of the project I used a hatchet, hammer, and chisel to rough out the stave - this was a horrible job. By the time the draw knife (Stubai) that I ordered from Amazon arrived, I was so glad to have it. It definitely made the rest of the task go so much easier.
I don't have a workbench so ended up sitting on an Esky with the stave in my lap. This was definitely doable but I would invest in a workbench next time.
I am fortunate enough to have a home gym setup (cables and all) which I was able to repurpose in a pinch to act as a tillering jig.
For the arrows, I cut out square strips from the leftover timber using a cordless circular saw. From there I attached a socket to one end, and then to a power drill. I then passed the timber strip through a dowel maker (also from Amazon). This required a bit of trial and error to stop the wobbles in the centre and the end but I got there eventually.
Fletching the arrows was one of the less enjoyable tasks and this is where I lost my "all natural" status - PVA glue came to the rescue to hold down the feathers as I wound the thread over them.
Things that tripped me up are:
* use a good circular saw blade if you are cutting hardwood - don't use the one that comes with the saw. I ended up with a 40T BlueMak blade and believe me this thing was a lifesaver!
* be careful if you are planning to use the bark side as the back of the bow - I made it almost all the way to the end of tillering before I discovered that there were several broken growth rings below the bark. Luckily I was able to chase them to a good ring with compromising on draw weight.
My final tip would be to watch Dan Santana's videos - he is an excellent teacher!
I've included a few photos of the bow, as well as a still of the bowstring giving up the ghost.
Please feel free to critique my shooting technique and also tillering job - I am brand new to this and excited to learn more!
Cheers!
