Topic: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

3 months later tl;dr it's a nice, fast, relatively affordable bow. I can draw it a few inches past my ear (33") while standing parallel, arrow going just under lip. My arm span from thumb to thumb is 69", 72" middle finger tip. Bow is very narrow and fast. Seems very durable. Just be careful not to twist it, although it's not that easy to twist. They gave me the right string length the first time and bow length, the bow string length is about 48". Length of the bow is 53", through the back unstrung I guess. Very good service..

This bow looks way better than a Samick SKB, though I've never shot the SKB... It looks way more like a gakgung, can probably be drawn farther  (same d/l for the 48" version?), is much more narrow yet likely still more durable. Not sure if this bow is outperformed by pricier SMG or YMG bows, or not. I can't comment on how it feels in comparison, nor the cast or anything, since I haven't shot those.

They sent me a second string that was longer when I pestered them, for free. Bow was still very shootable but I still prefer the first one. Higher brace height is more forgiving.






...

I ordered a 53" 45#@31" Nomad bow kit (comes with bag, arrows, glove, etc). That kit said the 48" bow was recommended, though, for some reason, but I chose 53".

I finally got it today, picked it up at the post office, and strung it.

Now a lot of people all over the world know how messy my room is.

The handle is pretty rough, but I guess that allows a firm grip. It's not bad at all. I like the look of this backing more than the pictures of the Kaya KTB. It's some sort of synthetic cloth, apparently.

The Hungarian bow on the left is about 50.5" nock to nock and about 54" tip to tip. But this is what the sticker on the Korean bow says.

And this is what I measured nock to nock. About 51" tip to tip? 48" nock to nock.

What the manual says...

124cm ~= 48.8"

This bow is the 53" version.

I was still able to draw it pretty far, to the tip of the arrowheads, before the outer limbs got parallel. (little over 33", with the carbon arrows it came with) Though it felt like it began stacking. Because of lack of strength. It does begin to increase in draw weight pretty quickly in the last inches of draw, but possibly only to 55lb at 33" or so. I have gotten better at shooting it with time.

The carbon arrows it came with.

Seems like the nock is way too wide for the string. They're very loose on it. Guess I will have to double/triple serve the string...

The nocks in the wooden arrows I have are barely thick enough to stay on the string without falling off, but still very loose. I feel like my Easton Gamegetter aluminum arrows, which have an even smaller nock, should stick just fine. If I added more serving, then they'd be too tight, so I can't shoot all my arrows with the same serving.

I will shoot this bow later today.

It's pretty easy to string with a step-through method.

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

Just shot this today, I could draw it far enough. I hit a small cardboard plate at 50 yards once! (most of the time I missed the target... well, it was uphill too). It's not exactly easy to pull far enough but easy enough (beginners: get the 30lb bow!). Arrows were 32" right before the arrowhead started.

Definitely a *much* faster bow than my glass/bamboo hungarian, and can be pulled farther back (hungarian has 31" max pull..)

Comes with white fastflight endless string.

I guess it's not that sad once I noticed that the top ear is more than 45 degrees of the horizontal. It's definitely stacking there... I really should be happy that I didn't break it
guess other Korean bows of similar length can be drawn further due to slightly longer ears that curve forward more
first arrow is 33" long.

Guess this isn't the 53" version after all, huh

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

I think your bow has a couple more inches of draw. Here is a picture drawing my KTB. In the photo my draw is 30 inches. I usually draw it to 31. It's the max draw for the 48 inch.

Talk to them about it, koreanbow.com's always been nice to me when I talked to them about problems in my order (thumb ring sizing).

Thanks. is yours 48" notch to notch as well?

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

They are sending me a new 125.5cm string, even though I didn't even ask for it explicitly. Very good service.

I must have shot at least 500 arrows with this bow today, I am very pleased with it. It is marked 특45 which is supposed to mean that it's the longer version, 45lb.

I was supposed to do a serving/nock point like this

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

I see so many people shooting with these square oversize handles. What you shoud do:

They are usually made from some hard foam and designed to be customized. Remove the wrapping, then carve it with a knife to suit your hand size. It can also be sanded a bit to finish it(by hand, no power tools) but be careful not to touch the wrapping above and below the handle. Then do a test wrap, shoot a bit, and adjust as needed. When you're happy with it,  rewrap with the material of your choice: leather, tennis grips, stingray skin, rubber etc..

If you cut too much, you can glue some additional material. I used some automotive radiator rubber tube I had around the house. Any rubber or hard foam should work.

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

Thank you. It wasn't that big, but I did what you suggested and wrapped the handle with yarn. It's better now. It was too rough before, almost felt sort of like sandpaper after a while... I had no idea that it was meant to be customized.

This confirms that my bow is the 53" version. duh http://www.koreanbow.com/shop/index.php … er=product

The "perimeter" of the bow is actually 53" after all.

I have no problems with their service or anything. They were very nice to send me a longer string to lower the brace height.

Now to learn how to actually shoot this thing well.. applying torque and all that

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

I am very satisfied with this bow.
The 3 carbon arrows that came to me on the kit were marked 80x80 (8.0x8.0), which would be 84.84cm (confirmed from the groove of nock to tip of arrowhead) and 463 grains.

I just measured the force-draw curve by putting masking tape on an arrow at intervals and drawing it from my foot with a fish scale... and the following program

import matplotlib.pyplot as plt
from numpy import trapz
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(1,1,1)
ax.set_xticks(np.arange(0, 33, 1))
ax.set_yticks(np.arange(0, 60, 5))
ax.set_yticks(np.arange(0, 60, 1), minor=True)
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)

ktb_draws = [6.5,7,9,13,17,21,25,28,29,30,31,32.2]
ktb_weights = [0,2.5, 9.2, 16.8, 22.1, 27.7, 34.8, 41.8, 44.8, 46.8, 51, 56]
plt.plot(ktb_draws, ktb_weights)
plt.axis([5, 33, 0, 60])
#plt.grid(True)


print("Foot-pounds of stored(potential) energy:")
print(trapz(ktb_weights, [x/12 for x in ktb_draws]))

plt.show()

Foot-pounds of stored(potential) energy:
56.09375

A straight line from 0lb to 56lb from 6.5" to 32.2" (25.7") would be 56*25.7/12/2 ft-lbs, or 60 foot pounds... so this bow seems to store less energy than a straight line f/d curve. Not that that's bad

https://static.pcout.in/51d6e075-a0af-4b4f-930f-308772eb4b81.png


The draw weight was measured from the belly, while they actually measure it from the back...

Seems like 32.75" (from the back, or 32" or so from the belly, that is, the base or root of the copper arrowhead almost to the bow's belly) actually is enough for me to draw past the ear, w/ the string going next to the earlobe, with a rather low draw hand in a Korean way. And it seems like the draw length for my 84.84cm (33.4") arrows, since they appear to be 33.4" to the tip.

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

The thing that might bother me most about this bow is, funnily, the synthetic cloth backing. It's kind of... I think I'd really like the look and feel of birch bark a lot more. But probably not the cracking. Besides, it's just cosmetic, not functional.
2nd is.. I guess it stacks a bit near the end of the draw, may be caused a bit by the short ears that aren't that reflexed. Still really good for being that short, though I guess other synthetic Korean bows may do better. Not sure. Seems like the horn bows definitely can be drawn more, and hold more reflex..
It seems to have taken a bit of set with use, I have to bend it a tiny bit into reflex a bit to close the bag.
Still a great bow and worth the money of course. May be narrower than SMG and Kaya bows? It's a tiny bit less than 1" long at the arrow pass.

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

I may have twisted it slightly.. I don't know. mostly just noticeable at a low brace or when drawn, but at normal brace it looks mostly fine, just the angle of a tip is a bit leaning to one side but the string bisects the bow well

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

the string i made slipped a bit. and one strand of the main string which I think was loose came off/broke off and i had to pull it through the serving and cut it off at the other loop
i guess the brace height is about 5 3/4" now
a bow square was surprisingly useful, i was nocking way higher than i should. maybe that affected the balance of the bow

https://www.postimg.org/gallery/1sb99d2v8/

The bow seems significantly louder than it used to be... maybe because of the lower brace? if not because of the string..

applying torque/khatra is hard and annoying. but it wasn't that other day that my bow was actually quiet and the arrows landed nicely and I was doing mostly rotating the bow to the side, not much forward (although apparently that's the most inconsistent khatra)

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

Ah shit, forgot to tell you. You should make the loop a little shorter than what you want and shoot it a bit to let the knot tighten (and get longer)

Re: MJ SYSTEM/Freddie Archery/hyunmugung manufactured Nomad

I had one knot that just wouldn't stop slipping. Maybe too much wax, or I had to tighten with pliers and an awl like in the videos.. I applied thin CA glue, either way.

I got a Song Mu Gung with a very similar draw weight (measured around 45#@31" and 56#@32.5", though marked 41#), but since it is shorter (50"), it actually feels like it stacks a bit more and the max draw is a bit less (maybe by an inch). Not sure about speed differences.
