BAMBOO BUNDLE BOW

A number of people have taken an interest in my bamboo bow, there was even a thread

about them a while back. I got the idea from Tim Baker's writing in Chapter , !olume

", of The Traditional Bowyer's Bible where he says that any collection of reasonablyfle#ible twigs will do, and includes a picture of a beautiful bow made of old arrows,

complete with points and feathers, to prove the point$

%o, there are a lot of ways this sort of bow can be made. This is &ust the way that I have

done it.

I like using bamboo that is about " inch diameter. It is easier to find the right si(e cane

in ) foot lengths than it is in * foot lengths. The bundles of si# foot stuff sold in garden

centres tends to have a lot of really weedy canes mi#ed in. +ou can use thin canes, but

you have to use more of them, and be smart about how you lash them.

The recipe is pretty easy. +ou want about five canes, the longest section doesn't need to

be more than * feet. Check that it doesn't have cracks or holes, and is well seasoned. If it

is still a little green it really needs to be baked a bit in the sun to turn it yellowgold.

There is a lot of info on the eb about seasoning and tempering bamboo. +ou might

want to give it a try. The problem with tempering bamboo in the round is that it tends to

split, it also seems to run counter to the idea of keeping the bow simple.

It is -uite possible to cut this si(e bamboo with a knife, no saws needed.



If you use a saw, make sure it has fine teeth, hacksaws work well. se a knife or file to

bevel the cut edges so that they don't make splinters.

There are two ways of laying out the canes. /ither have one *', one 0', one 12 and one

2, lash together every * inches, alternate the thick and thin ends from one end of the

bow to the other, you don't want all the thickest ends of the canes all in one bow limb.

The other way is basically the same, e#cept that you use two 0'*2 canes and stagger

them so that the thin ends make the limb tips, one each limb, This is instead of using a *'

and a 0' cane.

I have heard you can use gaffer tape instead of cord to bind the bow together. I have

used regular packaging string from 3 %miths.

The lashing is started with a Constrictor 4not.



Then carry on with a simple, but tight whipping

It is important to have sufficient width of lashing. If you were to &ust bind with a seriesof really tight constrictor knots the load under the knots will cause the bamboo to fail,

this is especially true of the first lashing at the tips. This is where the greatest change in

stresses occur.

To finish the whipping I tend to make some 5rapping turns, making use of the gaps

between the cane to get the string around.



+ou want to be lashing from the tips of the bow towards the middle. 6ashings to bind

every cane that will make the bow at that point, you don't want to be laying canes over

previous lashings.



If too many canes are used in the grip area you make the arrow do a lot of work to bend

round the bow. Better to keep it as slim as possible.

7ocks for a string are a bit of a pain in thin bamboo. Best bet is to take thin cord and

make wrap8on nocks soaked with glue. Bamboo is slippery and its hard to make

lashings stay put. If you cut into the can it will break, so tie on nocks seem the only

way. +ou could drill horn or wood over nocks as used on long bows, but again that is

more complicated.



3ere is one I finished earlier. I wanted to post and the glue on the nocks on the newest

bow weren't dry



The pictured bow pulled 19lb when brand new, that will fall a bit, but with string follow

:permantent C shaped set in the direction that it is strung; staying less than inches, it

shouldn't lose too much.
