Last Saturday was the day, to chrono some flightbows and flightarrows I did all over 2013.
The setup is like follows:
I found as much light as possible gives exact and serious results when doing chronos inside.
The queen of this session:
Success so far. But I was longing for more: 300f/s!!!!
I ignored my falling concentration and accuracy and ended up with 4 broken flightarrows, the 279,0f/s arrow is lost somewhere in the disorder of my workshop. I even hitted the wire rod of the chrony and failed the backstop, my hands and fingers began to suffer. Remember zen: don’ t overdo it, underdo it.
This blog has not turned into a stage for political debates in the face of the worldwide financial crisis. But I wonder Marx being so actual and very right about the behaviour of the big capitalists. Nothing more to add , but I support “Occupy Wallstreet”. Everything made by yourself will bring the power back to you. I´m still dreaming of a world without any political, financial or whatever leaders and the growing social networks make me very hope. Get your power back, that´s what shamans all over the worlds and times are telling us.
I´ve not blogged since weeks. Main reason was the best fall we´ve ever had here. From August till mid- Decembre we´ve had about 6 rainy days. Too dry for sure, but I could cut a lot of bow- woods ( black locust, rowan, whitebeam, mountain- maple………….), I´ve never had so many staves in stock. I could do a lot of fire- woods too, making some new fences, preparing the grazing land and a barn for our sheepfarming we´ll begin next spring. And a very sad thing has happened: in the last week of Octobre one of our horses, the brown gelding died of some diseases of age. We knew since about half a year that this will happen, but anyway, a horse is so big and he was for about 20 years a true companion!
Even I had been so busy, I´ve prepared a lot of articles about making retro- and other flightbows, flight arrows, about my bow- classes, for not to forget the finishing of the crossbow.
There´s to much snow outside, vacations, time for heavy blogging.
Some pics of soon upcoming bowxplosions:
So far, Christmas is family- time.
Cheers, 2012 is coming, have great times……………………………………
Last volume was dealing with the final shaping of the horn- lam. Now the horn- lam has to be backed with sinew- fibres. But before backing the prod has to be wrapped with bundles of sinew- fibres.
About a quarter of prod´s thickness will be the sinew- backing, 3- 4 layers of sinew- fibre- bundles has to be prepared. According to a total length of 30″ minus the recurves about 25″ of the prod´s length and an average- width of 2″ incl. the sides of the prod , so about 50 sq.inches have to be backed. As a total that means 4-5 buffalo- leg- sinews have to be spliced, at least a job of 8h.
Waiting time! At first I planned to finish the prod in April or May, that´s to less time for the polymerisation. I´ll do it at the end of August, 9 month after having backed the prod.
So next volume will be focused on the braced and ready to final tiller- work prod.
It is a must to degrease the wood or the horn, don´t use some of these chemical killers, just use a solution of water and pure wooden ashes. Take care: this is a killer too, it´s a base, historically used for degreasing, use some working gloves.
Wether to apply a sinew-backing to a wooden bow or to a hornbow, to precoat with a thin solution of glue several times is an additional must. Otherwise the glue can´t penetrate deep enough the wood or horn, the glueline is not as stable as it could be.
The sinew- backing needs to be well organized: the workshop has to be well tempered, the glue has to be heated up to 140F or 60C, too much heat will destroy the glue. To less heat will leave the glue to tough.
A dish of lukewarm water has to be prepared for to soak the sinew- fibre bundles about 2 minutes.
Thebow has to be fixed in a small vice.
The glue has to be kept to the right temperature with some tealights. The containers used for soaking the fibre- bundles and for the glue have to fit the length of the fibres.
Go on applying bundles towards the tip of the first limb. Usually 1 bundle will cover about 1/2″ of the width of a bow´s limb. The bundles should be applied staggered for not to end up with a running through the width glue-line.
The guy helping me this post to become true is Stefan, making a Hun- type style hornbow(asymmetrical). It´s his first sinew- backing. The sinew- backing just covers the v- splice with the siyahs.
Two additional layers will have to be applied. 2 – 3 layers of sinew- backing is enough, wether it is a wooden bow or a hornbow. Otherwise to much weight is added to the bow. Waiting time is beginning just right now. The elders have left a sinew- backed bow for 4-8 months alone. I don´t know why a lot of modern “primitive bowyers” are ignoring the fact that the so- called drying of a sinew- backing is in truth a polymerization. Polymerization needs its time!

Next volume is dealing with the tillering of a sinew- backed bow.
