My first feeble attempt at bamboo arrows.
with a candle and oil as described at "Ferret's Archery page" here:
http://groups.msn.com/ferretsarcheryweb ... rrows.msnw
I started with what we had in the shed and chose from bamboo cane
from some garden market (DIY). The 6 pieces I picked where not all
uniform in diameter. I.e. they could vary from 8 mm in one end too 10 mm
in the other (one where 9 mm -> 11 mm and ended up too weak after sanding).
One of the canes where of a different spieces/sort than the others in that
it's colour was green and it was straighter and more uniform in diameter all over.
Furthermore it was notably lighter in weight than the others.
As of now I have only testet two of the arrows. One "the green one" performs well.
The other one would have performed much better if I had paid attention to placing the
nock correctly. In Stephen Selby's "Chines Archery" there's an explanation of
"the sunny- /shadowy-side" of bamboo (one beeing denser than the other) and placing
the nock in relation to this.
By change I think I have managed to place the nock exactly contrary to what is recommended
(wan't do that again). This arrow drags to the same side as the cock feather (which accidentily
was placed on the softer side of the cane).
I haven't yet weighed the arrows and seen how all of them behave.
The two I have tested I have shoot both from longbow and my Samick SKB (40#). With the Samick I
have tried with both finger- and thumb-release (arrow passing over hand or thumb accordingly).
All of the shafts are approximately 8 mm after sanding.

The shafts closer up:

Next time I will try to pick better materials, be more attentive to detail and so forth.
I therefore have som questions to you who have more experience with bamboo arrows than I have.
My apologies if these questions are strangely formulated.
- How uniform in diameter is normally a cane one select for arrow? I mean there is a limit for how
much sanding one can do on a bamboo cane.
- When sanding these canes they become lighter (the heaviest part beeing the outer layer, correct?).
Normally I would use the (former) "thick side" at the point but if I have sanded that part down it
becomes lighter than the rear of the shaft and this would affect the balance of the arrow. Does one
turn the shaft around and use the heavier and more "unsanded" end at the point sometimes?
- I think I have seen references to tapered cane shaft. How much taper is normal here or is this
just possible with special types of bamboo?
- Do you just flex the arrow between your fingers to determine the soft or denser side of the cane
(I am not sure if I am up to the "water test" from the Qi arrow makers, mentioned in Selbys "Chinese Archery")
or is there a better way?
Species means a lot. There are 1200 kinds of bamboo and only a few are worth working on. Arundinaria is best, Pseudo Sasa Japonica is a close second, Sasa coreansis is just as good, Phragmites is historically the most common grass arrow, but much weaker than the others.
Collect the prettiest shafts only, several years old, dry for months. Those gardening type bamboos are incidently arundinaria, the strongest, but not the easiest.
The big decision is whether to make a self nock above the node, between the nodes or to insert a wood nock plug and where. Here is my discovery. If all shafts in a group look somewhat like eachother and they weigh the same, they are a set. The proof is to work an identification into the design and track the individual progress with out looking to see which arrow is being shot.
To check the weight you will have to cut many shafts to the same length and weigh them all and mark the weights onto then. I like the initial weight to be within one or two grams spread at the most.
Forget the oil. Bamboo already is full of wax which comes out with proper heating. You dont need to cook them to straighten them. If you leave scorch marks, they have gotten too hot. Use some gas stove flame on low with the shaft 6-8 inches above the flame and keep it moving.
Do not alter the taper or shape of the overall shaft for the reason you discovered. The thick end is the point for most all arrows. But do take off the thin skin so that glue, paint and finishes will adhere and for an even look.
Choose eastern motifs. The shaft is only half the arrow. The fletchings and lashings are the other half. If you have never started from whole feathers, are still using some prepared turkey fletchings, then you are stuck at arrowmaking 101. There are people hybridising birds just for their feathers out there, domestic birds. Match fine shafts with fine feathers.
But one does not need to start with a set, that is a large obstacle. Start with a matched pair or just one nice arrow. A 20 gram shaft will suit most, 22-26 for a big arrow, strong bow, 30 grams will kill a rhino. I think the sunny side argument was meant to throw you off, like collecting moonbeams. -j-
Also I thought they looked good.
This surface will now accept finish, paint or glue. I like to do the nocks before decorating. The nocks MUST be lashed, at the node or otherwise.
All fully noted here.
In my book on bamboo (which only deal with some chinese genera and species)
"arundinaria" is listed with several sub-groups. Is there any particular group
you prefer?
The nameless bunch I would get at a garden market here are those slightly heavy, yellowish
with a hard and smooth (almost shiny)surface. It not much information to go on but
does that sound like "arundinaria"?
The "grey/green" shaft I had might not be from the garden market here but be a left over
from some we've brought from China.
I also see I need a larger selection of shafts if I should try to make a set.
I thought about the placement of nocks this time. My selection of shafts didn't
give much of a choice though so I got to test nocks both above and below a node. :-)
My nocks are cut in the shaft but I first drilled the end hole to 4 mm and inserted a
4 cm dowel with some glue as reinforcement. All nocks are lashed afterwards.
You then let the arrow shaft be thickest at the point and then naturally taper towards
the rear rather then forcing the shaft to be uniform by sanding?
Now I will try these and see how they behave and then experiment with making one
or pairs of good arrows while I practice.
I agree on the "design and fletching advice.
electric drill, then folding sanding paper (#80) into this:
[external image]
I then start the drill and slide it up and down the shaft, applying pressure by
squeezing.
This is how I make wooden shafts; first by hand plane and then I "drill them smooth".
Jack's gentler approach to sanding is probably much more suitable for bamboo.
You need to carefully inspect them every few shots for possible splits along the length. This may be especially true where bamboo has been lying in garden sheds or garden centres and dried out completely.
If they fail when being shot, they can send off splinters that can harm eyes and hands of the shooter.
You are absolutely rigth. Those splinters are like carbonfiber.
I've gotten a couple of those in my fingers when splitting bamboo
for making kites. **shiver**
I put about 5 layers of lacker on arrows so hopefully that will slow
down any process of splintering. But I'll keep an extra eye on them.
All bamboos have shiney skin that is hard to adhere to if not abraded.
Stig; spinning bamboo would put marks across the grain, weakening the arrow. Kyudo recognises three tapers to bamboo arrows. There are those special bamboo sticks with no taper, most will taper toward the nock, some few will taper toward the point.
Shooting any arrow with a damaged surface is dangerous. This danger is amplified by strong bows. -j-
> Stig; spinning bamboo would put marks across the grain, weakening the arrow.
When you mentioned it. I noticed on some of the shafts that they got more visibly marks than
on a wooden dowel. But I think equally important is that your way of sanding the shaft
gives better control with how much you remove. The way I did it could easily end up with
removing to much bamboo thus creating weaker parts/spots.
I'm not the expert here, but in my experience you need to pick abustedarrow wrote:
I might have missed this but How much can you sand off the bamboo? , If you want to try to get the shafts the same diameter.
shaft that as a start has a more uniform overall diameter that again is not
far from the diameter you want to end up with. That said it would still be
rather individual (for each shaft) how much you can remove without weakening the shaft.
Nice to find another bamboo enthusiast; most people I know fight shy considering bamboo to be a nuisance. I grow a few different species and I've often been tempted to make some arrows from them. The Chimonobambusa Quadrangularis is definitely not a contender due to its square shaped culms and very pronounced nodes. Have you ever tried Phyllostachys Nigra? I wondered whether the beautiful black colouration remains after sanding.
Another very nice specimen that may have potential is Drepanostachyum Hookerianum 'Damarapa'. The culms are nice and straight with hardly any swelling at the node because all branching is very fine. The colouration is very striking with pink and cream stripes and the internodal length is quite short, even on the largest culms.
Pseudosasa Japonica should produce some good results if its common name of 'arrow bamboo' is anything to go by. The culms are indeed very straight. The bamboo specialist that supplied my plants considered this species as uninteresting, saying "most people who have bamboo have this one." He was a little more interested when I explained the size of the clumps I have, they are literally a forest at the far end of my garden, four huge clumps about 8 to 10 feet in diameter.
I'd advise anyone interested in making bamboo arrows to buy a small plant, within a year or two you will have all the supplies you need.

Black bamboo only has black skin and the skin is removed to make arrows. But a large black pole makes a fabulous bow backing. As you may know black bamboo has green poles which turn black on a single freezing night. If it is not cold enough, it becomes tortoise shell; an even more desirable color. But black is too tapered to make a good arrow. It grows well in Texas.
Pseudo sasa Japonica is the stuff of Japanese arrows. Need I say more? Blissful perfection, made in heaven for arrow making. When the sheaths begin to disintegrate, they are ready to harvest.
You can go through the list if you want but I have mentioned the best species as I understand them.
Do not reshape arrow bamboos. Remove bulges and the outer skin judiciously. You will only get good arrows if you start with good sticks.
Yes that's right, Damarapa is native to Bhutan and north east India in the Himalayan foothills. The photograph on the site in my link really does not do it justice.
As for the Japonica, you have confirmed my suspicions, I'd heard it was the arrow choice of the Samurai. Maybe I will try making some arrows but I doubt I would actually use them for the reasons Stephen has already posted. Any exploding arrows are a worry but I shudder to think of the consequences with bamboo.
It would not be good to shoot one which was oversanded. The strongest wood is at the surface. Just remove the thin skin and the bumps, no more; don't change the taper.
I did want to mention that my observation is that the Indo Persians were using Arundinaria for their arrows, or a material which looks like it. Of the arrows I have seen, these do not remind me of Phragmites. More investigation needs to be done.
Therefore I find gardening stakes type bamboo to make good IP reproductions. -j-
Reto
The Korean/Japanese arrow makers match the nodes as best as possible. They have excellent bamboo available (pseudo japonica or koreana) which we won't be able to get from Walmart or any garden shop/centre. I prefer selfnocks or horn-inserts and I cut off the bamboo 1 cm above the node.
Some further some hints/information:

Good look and give it a try!
Reto
Because of our damp climate I have bundled them together and tucked them away in one of my rooms (hopefully hidden well enough that my wife overlooks them) to dry for a couple of months.
I had considered horn for the nocks, it's available quite readily in small sticks specifically for nock inserts and such so that's a bonus. I normally use 100 grain brass bullet piles on my arrows so I will probably try those. Do you suggest an optimum diameter? The canes I cut range from around 15 mm tapering to around 8mm or so. Many thanks again.
I am getting jealous about your weather temperature. Here in Switzerland it is cold and there is snow everywhere. The traffic collapsed - good time to work on my bows and arrows ....
Reto
Those arrows are very nice. But I am wondering about the spliced feathers arrows. is that a dowel spliced in the cane under the feathers?
Matt
Am glad to see others who enjoy bamboo arrows. -j-
A word of advice to anyone harvesting their own bamboo....COVER UP!!
I forgot this golden rule and I'm paying for it today. I did not wear gloves and merely the act of brushing the culms to one side with my left arm has left my hand and wrist red and sore from abrasions and tiny micro splinters and that is only from the dry sheathes at the nodes. These sheathes cling on to Japonica for a long time, years even and they become very dry and brittle.
Thanks for those links, I will follow the arrow making instructions religiously.
On a side note, legislation and silly rules tend to get in the way too often these days, at least here in the UK that is the case. Archery governing bodies make it extremely difficult for the Traditional Archer because of their ridiculous classifications. I am a member of a Field archery club which is a GNAS affiliate, we had a group of 'team GB' squad members at the club last night ready for squad training session today. Knowing that GNAS rules regarding 'trad' are particularly bad (they allow modern recurves as long as wooden arrows are used yet always raise an eyebrow during equipment inspection over the binding on my Hun) I decided to ask a judge about using bamboo arrows. Obviously this has never arisen before because he was unsure. The outcome was that FITA rules make no stipulation on materials, where GNAS rules state wooden arrows and bamboo is grass. He saw no reason for bamboo not to be allowed other than complaints by any archers who you may happen to beat; they will need to look into it :roll:
It is so annoying having these silly rules applied by people who regard traditional archers with some contempt compared to the 'sights and wheels brigade'. Thumb draw is not allowed yet trigger release is fine. I keep fighting the Asiatic corner, maybe one day I'll succeed in getting our own classification.
I sent....
Dear GNAS,
I have recently begun shooting my asiatic bow with a thumbring
technique, meaning I pull the string with my thumb and forefinger. I
also wear a ring on my thumb to prevent bruising.
I intend to use this technique over the three finger draw commonly used,
however I should like to know if this technique would be acceptable in
GNAS tournements.
I got....
'Mike
Sorry for the delay - I've been trying to get an answer for this enquiry from the chairman of the Judges Peter Morris. I have now received his answer as follows.
'For the type of bow and the style, it would appeat that there isn't a problem in the way that he wishes to shoot. Only purists would argue that the thumbring on the thumb is not necessary and could be interpreted as an aid ' .
I hope that this answers your enquiry.
Kind Regards
Stephanie
GNAS'
It appears that they think a ring is different from a tab but really I can now hold this quote up high at the next tournement I go to if anyone tells me I am unsafe.
Mike
These governing bodies should really start looking at ways to embrace all forms of archery and encourage those of us who take part for the sheer enjoyment rather than rankings and prestige. It's a sad fact that the 'trad' class has so few entries, I suppose the learning curve is much longer and most people opt for the instant gratification that modern equipment brings.
I was shooting at a target with a very accomplished modern recurve archer, a good longbow archer and a beginning recurve shooter. I was using a Korean bow and Middle Eastern technique. Everyone was encouraging each other.
A standard thumb ring without groove or hook acts just like a tab. At target distances, I would not choose one over the other. Sometimes I shoot with a metal ring and others with a replica leather Mongolian tab that Dr Grayson made. There does not seem to be any difference in accuracy.
Saying that bamboo is a grass and therefore not wood is like making a differentiation between decidious wood (the leaves fall, like ash) and coniferous(with needles, like port orford cedar).
If it were said that bamboo is hollow, one could point out that NA Indians used dogwood arrows that have a pith center and are therefore hollow.
It is simple to proove that wood is wood is wood. -j-
Bede,
In all honesty my club is just like yours, we have many styles and there is a great atmosphere. From being the only Asiatic I have encouraged others and the 'horde' now numbers seven; three Huns, two Magyars, one Scythian and one Mongol and definite interest by a longtime compound archer. However, there is no getting away from the fact that shoots are aimed mostly at modern archery. More than once my wife has failed to hit fifty metre targets due to overhanging branches.
Mike
What I do appreciate is when extremely good archers with high tech equipment take time out from their shooting to complement a traditional archer on a good shot. Some of these people invest so much emotion and commitment to high precision shooting that I am impressed that can equally enjoy the success of their low tech colleagues.
I have seen competitions that had a Japanese bow, several Hungarian and Korean traditional bows, two types of longbows and every piece of modern equipment you could imagine all lined up and shooting.
Our compound archers are a great bunch and are constantly fascinated by the accuracy of my Hun. Of course accuracy drops far more quickly with any traditional equipment when distance to target is increased and I still miss a few. And on the occasions that arrows go awry, most archers are happy to help search...but there are the others. In fact, when I give up the search as a hopeless case most are generally quite sad .. "it's a pity because they are such beautiful arrows"
My complaint is that traditional archery is struggling compared with recurve or compound and that it needs people to promote it, which I do whenever I get the chance, explaining the satisfaction of making your own arrows and such.
Mike
OK, back to the arrows.
I have pre cut the Japonica shafts to length and dried them for a month, they are a few seasons old so not new growth. They have turned from their dark green colour to a pale greyish green, is this long enough?
I have a small portable barbeque, some charcoal and two bricks ready for the heating process. Matching the nodes and getting similar diameters is a very difficult job so I cut some more canes yesterday. Hopefully I will get a few that match.
Bamboo grows best when trimmed back about 25% per year.
T
How marked is the taper of each culm and how far apart are the nodes? I am finding that established Japonica culms are ranging from 15mm or more down to about 8mm around first branching; this is along a 3-4m length. My POC arrows are 5/16 and trying to get a similar diameter at the nock, the majority are more like 12mm at the pile end. Each node is around a foot apart but with some variation, meaning I have about 3 sets of varying number where the nodes match or are very close. Of course, each shaft will probably weigh differently so I may be going the wrong way looking to match the nodes. At present it is obvious to me that I could cut about a hundred culms to achieve half a dozen matching arrows (weight/node distance) so would I do better to concentrate less on matching the nodes and more on diameter and weight?
Jack,
The bamboo I planted has been thinned out annually but unfortunately the Japonica was long established before I moved here nearly 20 years ago. Imagine 4 huge, tightly packed bundles of bamboo about 6 feet in diameter. Trying to get in amongst the culms is murder and cutting them close to ground level is well nigh impossible but I could probably get away with cutting about 3 feet up and still have plenty of cane to use because the diameter I'm after is near the top of each one. I'd like to see how well I manage the straightening process before I cut more, if I do a good job and the arrows match my POC's for performance I'll never need to buy another shaft.
http://www.junglegiants.co.uk/acatalog/ ... onica.html
It does run which is why I have 4 clumps of it and I also have another clump starting to form but is nowhere near as invasive in its running as Quadrangularis, for example. I would guess the original planting was made around 30 years ago.
I cut some more anyway so I have a total of 50 canes to work with.
The entry path will soon grow back. -j-
I am assuming that the cellophane is wrapped around the sinew and nock as waterproofing for that joint? I have 10mm horn dowels that I will be shaping the nock inserts from so perhaps I can get away with just wrapping the sinew and the base of the nock. I've also had the good fortune of receiving a present of 4 pheasant left wings which I am very happy about.
The main concern I have now is the choice of pile. My arrows are fitted with 100 grain brass bullet piles with a 5/16" outer diameter which requires the first 1/2" of the shaft to be reduced to fit (parallel insert not taper). Maybe a 5/16" inner diameter would be better but I've always avoided these as I don't like the lip they create, making drawing arrows more difficult. The Korean piles seem to have a good inch of shaft in them which would be a more secure fit than the 1/2" that I will have to glue. Any suggestions? How well does hot melt work with bamboo?
The Turks sometimes covered the sinew wrapoping with gold leaf to provide moiture protection.
For those of us who don't have space to grow bamboo, is there a retailer anywhere about?
Cheers
Mike
Matt
That part is a long way off at the moment so plenty of time to come up with a solution.
Indo-Persian arrows for target shooting had conical piles with a tang. The ones I have were bound with sinew from the base of the point to just past where the tang ended.
Y?cel's book refers to wooden inserts in reed arrows into which the tang of the arrow head was inserted. The surviving ones were range (menzil) and war (tirkesh) arrows. I think the choice was determined by the wall thickness of the reed.
Despite the fact that bamboo will grow in certain parts of the Middle East, it was not native to the area. It was introduced in the last hundred and fifty years, but I don't know when exactly. Because the Turks used the same word for reed and bamboo, it is difficult to tell them apart in the texts. There is a separate word for bamboo in Turkish which descends from the same root as the English word. It is not used in the old texts as far as I know. Since bamboo arrows were not used on the Steppe, it is unlikely to have been brought to the Middle East by Turks from Central Asia or the Mongols.
Reed arrows were common however from ancient times and have been found in Egyptian graves and the Roman fort of Dura Europos. These usually had foreshafts and sometimes used inserted knocks of hardwood. The Dura Europus arrows were self-nocked. All used sinew wrapping.
The taper is not very perceptible, although you can see it slightly. I'll have to find my calipers to get an accurate reading, though.Orda Khan wrote:

The ferule is squared off on a grinder, etc, marked to length and cut off with a tubing cutter. this gives one rounded end and one squared end.
Preweigh each shaft readied for points. Match the lightest shaft with the heaviest point/ferule combination. Small wood plugs can also be glued in the ends before installing nock and point. In this way exact arrow weights can be acheived.
Taper the butt of the shaft about one degree and force/tap into the ferule. When the shaft is bottomed into the ferule carefully drill the hole for the tang (You can use the tang itself and worry it into the shaft. When the point bottoms against the ferule you are ready to glue.
Small amounts can also be ground from the finished points to achieve ideal weight.
This point will not wear as a sinew-wrapped one will. It is authentic. -j-
@ Thomas,
Thanks for that information. After seeing those Korean fletchers at work and all the shafts matching at the nodes it made me wonder about Coreana. About how tall does it grow? My Japonica can be upwards of 4 metres and the nodes seem further apart.
If I could find a bamboo specialist who stocks Coreana I would definitely get a plant. Is there a supplier over there who will sell bare shafts?
I see some of the culms grow up about that much.Orda Khan wrote:

Yes, I can get bare shafts here, either heated/straightened or raw; I'm considering harvesting them myself, but the fletcher gets the best quality (from NE South Korea).

I am enjoying working with bamboo but the process is very time consuming and there is no way I could compare my work to the masters. I would like to find a weight that works well with my bow, once I do this a matching dozen would be very nice.
The horn dowels and sinew arrived this morning, I'm looking forward to shaping the horn into nocks. I'll also be phoning a friend who's a plumber about the brass tube, I like the sound of that pile attachment.

What is that under the pile?

20$...yes a bit expensive for bare shafts but I'm guessing they are a much closer match than 3Rivers sell.
I can get bare POC shafts matched within one pound for ?23 and I know a guy who makes very well matched arrows who charges around ?8 - ?10 per finished arrow. I would still wager the Korean shafts are more closely matched.
I do not use a thumb draw so I've yet to find out if bamboo arrows will suit my bow. I hope so.
edit: Should I soak the sinew first before I bind the nock end?
I just finished binding the nock ends with sinew and hide glue....I bet those Koreans don't get as messed up as I just did :oops: My first attempt was not too great but the others are more evenly bound and look a lot better.
I want it to be durable.
Matt
You make very good looking arrows!
What is that "red eye"?
I ended up with only one pheasant wing, my friend was horrified when he discovered maggots on the other three and threw them away :shock: Unfortunately he did not have the presence of mind to remove the feathers first. Though I like the fletchings I use on my tournament arrows (white, low profile parabolic) I'd rather put some really nice fletchings on these.
So, how much heat it must be applied to the shaft? Untiil will become brown or just only enough to straightening?
The shaft is really hardened by heating or is just heated to straightening?
For example Stig's arrows looks green.
Reto

You can see in the first picture I posted how the shafts have dried to a pale greyish green, they were dried for about a month to get to this stage. The amount of time I spent heating each shaft depended on how easy they were to straighten but I'd guess it was around twenty minutes per arrow. Even after that time, I had areas that still looked a bit greenish. Sanding away the outer skin revealed a light brown colour underneath, similar to untreated POC shafts.
I found that with heating, they sweat a waxy substance and are easily straightened at this point. I wondered the same as you because they were still fairly light in colour and I was worried about heating them too much. It is easy to scorch them if you are not careful.
The diameter of the shaft is no clue to the weight as some are more dense than others. Of the dozen I have prepared I have been lucky, I have seven that range from 330gr to 355gr and five from 300gr to 317gr. I've begun making horn nocks and these weigh around 20gr. My POC arrows are around 400gr so I'm a bit concerned that the finished arrows may end up a bit on the heavy side.
I cannot recall any specific information that heating wood eighter improves or degrades charistics in wood. However, I have never seen a Japanese, Korean or Persian bamboo arrow with a scorch mark on it. This much heat is unnecessary and possibly damaging.
Khan; one month may be too little drying time. You will notice pale shafts are not as mature/heavy as others. You gave the weight but not the length. -j-
Very true, I found exactly that. You get somewhere near straight only to see the shaft return to its original shape.jack farrell wrote:
It is much easier to straighten a shaft if only the area desired to be bent is heated. Reheating a straightened area tends to induce the bend to return.
The shafts in the first picture are still drying, the ones I am working on were an earlier batch. I still have the thicker offcuts from the early batch and interestingly most of these have dried to a light golden brown.
I straightened three more shafts today that were around 300gr so I may yet achieve six arrows around 400gr finished.
I've cut them all to 30 inches. My POC are 29 inches.
Remember I told you that 20 grams would suit most archers (312 grains)? -j-
Unfortunately, as was discussed at WTAF, the stable is in danger of becoming empty... :(jack farrell wrote:
There you go straight from the horse's mouth. -j-
Let's hear about your journey to Paju, Jack :)

I have seen film of Japanese archers heating the entire shaft while straightening it. Added to your experience, this suggests that it was a very common method. The Bhutanese do not heat the shaft according to a conversation I had with Tsewang Nidup in Fort Dodge. Most of the Indo-Persian arrows I have show signs of heat treatment.
In the Traditional Archers Bible, there are comments to the effect that heat treatment hardens shafts made from shoots. I think it was in the context of making grooved arrows in the plains fashion. I have not tested this myself though it should be easy enough to test a shaft, heat treat it and re-test.
you can tell by how much noise the arrow makes how straight it is. -j-
There are paintings of this from the 10th century. Good ideas seem to last. It is a bit difficult until you get used to it though. As usual, when a group of archers get together, there are things to learn.
It is always possible that the heating is to kill/prevent borers. -j-
I read that once ;
"....very fine awl (or pin) to poke each chamber at the node (this lets steam pressure escape)...."
and for some reason I thought that would be poking through the nodes inside the shaft.
Not having such a long awl I abandoned the idea.
Makes more sense now that's for sure.

Perhaps this was because the natural feathers on the bamboo were more forgiving than the plastic vanes on the modern style arrows. It wasn't a scientific test and certainly not definitive.
T
You just swore :wink: I'll be honest, I've never used ali or carbons.
I've mentioned before that my wife uses a 25# Grozer Hun (she's only a little 'un) and she is drawing less than that at 26". Her bamboos are about as fast as my woods, the compound archers especially were impressed with the difference. Everyone has asked the same questions though...
Are they weak here? (the node)
Can't you sand this down further? Won't it affect the flight? (the eyes)
I quoted some of the stats from the Hwarangarchery site and they were amazed at the speeds, even more so when told what kind of bow was used.
I have not done this with other species of bamboo. Phragmites reeds are hollow in the nodes except for a thin septum which has no strength. I am only talking about the ones I have examined.

Bustedarrow,
I applied varnish between the fletchings, over the lashing and the self nock. The rest of the shaft I used car wax as the Koreans suggest.
Regarding the nocks, I've see full horn ones that are stuck on much like modern plastic snap nocks, and I've also seen self nocks with horn inserts. Are either of those stronger?
I did have a play with some bamboo when I first started shooting, It struck me as odd that my wooden arrows were flimsier and heavier than beanpoles.

As you know, I began with making shafts with horn insert nocks that I fashioned out of water buffalo horn dowels. I finished a few of these and it was the work involved that made me decide to go with self nocks on the arrows I made for the wife. To be honest and I'm not sure if it is anything to do with the horn etc but hers turned out much better. I will be using self nocks on all in future. The problem I envisage with with obtaining shafts from a garden centre is matching weights and finding a small enough diameter. From the culms I cut I had matching diameters that were as much as 70 or more grains in difference. As these dry further I expect to see the weight drop and hopefully I will get enough of the correct weight to make a good matching set.
I am currently setting up a new PC and as soon as I get the chance to reduce the photos I have I will post them. Fitted with 63gr piles and 4" fletchings, hers weigh in at around 260gr.
edit: Silly me :oops: here they are
I don't think I will have a huge problem finding the right diameter, I use 23/64ths anyway.
It seems that most people dry-heat to straighten the shafts, is batch steaming acceptable here as well? (I'm guessing already that the answer is 'try it')

It may be impossible to determine exactly the species but appear equal to arundinaria.
Orda; Beautiful arrows, white eyes, white nock lining. Painting the inside of the nock actually helps see the arrow in the target, as you must know. Superior workmanship. -j-
I used a small POC insert at the nocks which I think finished them a little nicer than leaving a hollow. Unfortunately the auto flash spoiled the second photo a bit.
I've always used POC shafts and being a natural hoarder I have many off cuts which I knew would come in handy one day :wink:
