The only 'walkthrough' for making these kinds of bows that I'm aware of is this: https://www.instructables.com/id/How-to … p-by-step/

why not cut your own foam for the bow to sit in? some sort of fancy sports case

also, I think master Heon Ku Kim does a little bit of a "fixed crawl", allowing some space between the thumb ring and the nock, about one arrow diameter's distance? I'm not sure of how common this is. Might help with the bulky nockpoint discomfort

An endless string is probably best to start with. Are you using the wide Korean type nocks? where'd you get your arrows? either way, ideally I'd just go with a thick enough serving to fit without double serving, from the middle of the string up about 6"/15cm. The tricky thing is knowing how many strands of material, and what thickness of serving material is needed for a good fit

It may be easier to just modify your current string or buy a string for that bow, and double serve for at least about 3" so the nocks fit, if needed. Then tightly tie a nock point that sits atop the nock like ragnar says.
Should be more durable with dyneema/spectra braided material. or could use a brass one if you have the tools

It seems like those nocks may be too narrow for that string... they shouldn't be too tight.
Or maybe they partially slide off the string, the string should remain at the throat of the nock?

are the shafts 32", or the whole arrow? I'd need the shafts to be 32". Would be nice if I could find inexpensive, ~700 spine, low gpi (light), 32" shafts for my 30#@32" segye bow

I ordered a Segye Korean bow from alibow. The grip was too small to shoot comfortably with a Korean style low wrist, so I padded it with paper and glue, and wrapped it with leather. now it's all egg shaped, somewhat deep and fits the hand nicely. The string bridge fell off and I put the tip on the ground to unstring it and it broke off, i'll have to reglue them, but the grip is still doing fine. But still, hard foam could  be better

For comparison - the brace height of my Windfighter and my "Forever Carbon" (White Feather, supposedly the same bowyer, FreddieArchery) is 5.7 inches and 5.9 inches, respectively.
I would get the string replaced.

The Windfighter is Kaya. I'm pretty sure Freddie just sells rebranded hyunmugung (the Nomad line?), songmugung and taegeuk bows, as well as the hornbow. might be wrong about hyunmugung..

in yours it looks like the hole is not long enough and too narrow?

Here's a 3d model I modified, of a ring.. I put a piece of leather on it and it's pretty good, printed with wood PLA and tested with 50#

would hide glue be good for birch bark?

It would probably work.  I know that my old horn bowyer friend used contact cement thinned with benzene (from what I remember), but a natural glue should be fine.

It might've been a culprit to his paralysis? I think I'd (hypothetically?) rather try thick hide glue after sizing with thin fish bladder or hide glue. I've heard good things about it. For synthetic, Titebond 2 or 3 would probably work well too.
But I don't think that would help with the cracking... maybe it could just be ignored, while continuing to apply... maybe tea seed oil. Olive oil will smell rancid after a while.

I think that grip style's existed since at least late 1800s

yeah, i dont know how they can do a low wrist comfortably with those

So they're nice for Korean bows, then

But that bow is so short..? probably max d/l 29"?

I dunno.  Hopefully 29# @ 31" means it can be drawn to 31"

Hmm. My 50" bow takes 32" max. Maybe half an inch more, but already stacking. My 53" bow can reach 33". So the ratio is around 1.55 min

The Guru is 44", so... 44/31~=1.42.

44"/x = 1.55 => x = 28.38"

I just think the limbs will be past parallel. It'll be interesting either way. I doubt that it'd break, since it's pretty light..

For me that's when my elbow is pointing at the ground rather than to the side.

How "inside the palm" the bow's handle is, affects that too.. still not sure of how I should grip the bow exactly. There seems to be plenty of variation possible anyway.

Sounds good.  I've got an old Kaya 50# but I can't put a lot of hours on it daily so I ordered a Freddie Guru in 29# @31 to alternate & give my muscles a break every 2nd day.

Hope the Kaiyuan's no slower than the Genghis model

i'd like to make cheap glass and butted wood Korean style bows. could have a lot of reflex if lower draw weight and somewhat wider...

Maybe that's why it performs the same as the solid glass one..

Get calipers and consider https://www.customthumbrings.com - the spur ring seems nice...

I should 3d print more thumb rings soon. I have 2 other people on my list for 3d printing rings to..

With torque, you can shoot the stiffest arrows you want. But I personally want to shoot without it, or with a very minimal amount maybe.

What Alibow one are you getting? Segye? That's my practice bow for now. I padded the grip with paper and leather because it came too small.

Another option is Black Eagle shafts, but those are rather expensive.
There's also Alibow.

How do you know what spine you need?

If you torque the bow handle, I think 600 spine should work.
If you don't, it's hard. Maybe 1000. Maybe 700.

I'm guessing I need around 600-900 for my 31#@32" bow. I'm going with wood... problem is they'll end up being 14-15gpp. Bit high for a Korean bow... Which is why I kinda wanna barrel them.

Though my ~12gpps fly kinda nicely, point on distance close to 50m

The smaller handles just suck for a Korean style low wrist grip, IMO. You may want to build it up with something. I did my Segye korean bow just by gluing a bunch of paper from a grocery bag on it, then covering with leather.

Maybe the brace height is too low, too.

Sometimes I "randomly" start getting hit in the bow arm... then it stops... .

You are drawing to 31"? It's strange that the Kingdom feels worse. It looks very similar, a bit lighter than the gukgungwon in your force draw curve. 48" version?

My 53" Nomad KTB feels smoother than my 50" Songmugung.. can draw 8 chi arrows (32.5" draw) more comfortably, while I think my songmugung hits a wall right at 32" so I use 7.5 chi arrows with it. I couldn't tell which was faster at 10m. Maybe i should try a longer distance later. They have very similar draw weight.

I was kind of expecting the Nomad bows to be faster than the Kayas. Guess not?..

That's a very nice length for the Tatar.

Yeah, I get what you mean by the shot event being protracted. I guess it becomes less of an issue with longer distance, but then the measured speed will be lower because of air drag on the arrow, and even gravity (unless one measures the distance of the curve the arrow takes vs. the straight line distance)
