Just got some 100 cm shafts from oulay bamboo today.
They came very straight, polished and spine rated.
I will try them very soon.

I do agree that bamboo should came from bowyer.
Madake from ordinary bamboo dealers may be too young or wrong size.

May I know if >90 lb bows are historically used?

Limbs are theoretically fastest when dryfire, (zero arrow mass).
When arrow weight is very low (10,20 or 100 grains pellet) limbs are moving near dryfire speed because total mass (limbs+arrow) is not very different from limbs mass alone.

I think KAYA KTB rate DW at 31" so your 330 gr arrow may work fine as 7 gpp.
If you have chrono around, you may make a regression plot with different arrows and plot a regression curve. The dangerous zone will looks like plateau.
Korean bows generally have very low limb weight per working pound. So they are less prone for low gpp and dry fire damage as less inertia could be delivered to bow's structure.
I, however, shoot 8-9 gpp  big_smile for my bow's safety, arrow stability and long distance flight.

Measurement of circumference wont work for this kind of interlocking thumb ring.
I will need width and thickness of the drawhand thumb knuckle as the ring will lock at this place.

For the price, it could be great. You firstly need to master the technique. And then show the other archers how fun and cool thumb draw is. You need to build skill and join some international traditional archery festival. Then you may then buy me a meal at the festival.  big_smile

If your place close to Sydney, you may learn some techniques from Bede as he is also a thumb shooter.

I usually get 32-33" arrows. Too long shaft wont hurt.
I would start with carbon arrows as they are more durable and safe for beginners.
Chinese and korean bamboo arrows are ten times different in both price and quality.
But, so far, my chinese bamboo arrows are shoot ok in 3D match.

@sissara: I am still waiting for a call back from customs with the final ok, but it looks like I might be able to take you up on your offer. If I understood the guy from customs right it would be permitted basically as long as the waterbuffolo is not classed as an endangered species. He said he would confirm this for me and give me a call back. smile

Sounds good news. your may give me the measurement of your thumb knuckcle 1) width 2) thickness I could start making it this weekend. You may have only one color option, black as I do not have albino horn at this moment.  big_smile

Last time my australian friend told me about importing of some kind of organic materials to aus may require fumigation... with recipient cost. That 's why I asked.   smile

I would happy to carve you a thumbring but I am not sure if sending a piece of carved buffalo horn to aus will against aus law?

Double served means that you have string, then you have a layer of serving and then another layer of serving. You may remove one layer of serving to make the whole bundle suit conventional arrow nocks.

I bought a #55 YMG from the festival too. Compared with my current #50 SMG, I feel YMG has a little stack in the last two inch  neutral Don't know if it 's only feeling or the bow is actually stack. I need to check it with a scale.

I had indeed tried excessive string twisting as shown in movie. The arrows just fly with excessive fish tailing at the beginning.

Here is a horn ring I made before I got some plastic standard thumb rings from korea. Don't use it too much anymore but I like the design.

Cool design.. but I have no idea how it fit with thumb.

My hwarang gung (I think it 's FRP limb from YM gung) also has some stain on its back after 3 years service. I am thinking about replace the backing fabric with silk. Anyone has experience on this thing? What 's the best way to remove the glue?

From their official page, there are bridges on the limb.

The main purposes of heat box are driving out moisture and eliminate temperature cycles. It 's set to only some degree above room temp. Then you will need hot plate for bracing.

big_smile Good luck with your bracing.

1) It is recommended to use a heat box before stringing.  I haven't built one yet but was curious if there was a tutorial on how to make one.  Also, is the standard protocol for it to be left in the box every 5 days and if so how long?

Elite members in our club who use real horn bows kept their bows in the heat cabinet almost permanently. What you need is a simple cabinet. Add some insulation and electric heater to control the temp. I think pet stores may have good offers for those temp controller.

2) Is there an alternate approach to the heat box method like say using Colemen propane burners to heat the bow before stringing?  If so, how long should bow be heated over source and how far away?

My school use resistive electrical heater (those with heating element).  Hard to tell heating duration and distance as they move their hands by experience.

3) Is it always necessary to use the Dojigae or can one sometimes string it like this man did towards the end of the video:

I found even experience archers also use the jig. In our school, only one who could do bare hand/knee bending is the master.

4) I was given wrapping material for the grip of my bow (see below).  To adhere the material to the handle, what type of adhesive should I use.  Hide glue maybe?

For practicing bows, my teacher suggest the low end rubber glue as removal is easy. I do not have any idea about the traditional one.

You don't want a strong one, because it could possibly just snuff out the matchcord without firing.  The main thing is that the cord is delivered to the primer pan. 

Here are a couple videos I did of mine.  The first is just a short clip (also with a flintlock pistol).  The second was last fall at the Korea Military Academy; in that one, I had long hangfires, due to a problem with my matchcord delivery (the "yongdu" [serpentine] is set too far forward, so the matchcord does not hit the priming pan well; I have to get that fixed).

Many thanks, I had seen the first one but the image is not very clear. The second one is very clear and helpful. Thank you very much.

I use to shoot like you, Warbeast. It 's ok as long as the shots are consistent. But my master doesn't like the way bow hand drop too fast. He explained that the follow through reflects not enough pushing on bow hand (or pushing to the wrong direction or using the wrong muscle).

I heard that spring for snap type matchlock should be quick but not strong. Is there any video for the mechanism at work. I have no idea how fast/slow the spring should be.  smile

Just get the one with long enough shaft and 50-60 lb spine. Arrow spine doesn't affect much to us, thumb shooter, but I always go for a little high spine for safety. If possible, request the wings a bit far (1.5-2") from nock so you have room for index finger.

Technically speaking, rotating the bow to a half round or just dipping with slightly rotate are very similar as the arrow diameter is so small (7-9 mm).

The arrow 's also so fast. If you look at the video t=5:29, the arrow touch the bow anyway. Large or small rotation are just a product of follow through which happened several millisec after the arrow left the string.

I saw some historic painting show foot archers shoot their bow with their bow half turn rotate (cant find it now) and I have  practiced that style since then. Personally, I found the style 's fit for me as I had zero hand shock and my gripping, pusshing are more consistent.

Unlike Japanese Kyudo, Korea archery seems to be more flexible in term of minor detail. I attended one school, had one master and three teachers, they told me the same basic technique but they have slightly different detail.
