Just though I would share my little warbow here too :)
I finished it long ago and shot a couple of arrows from it, but after checking it with Badgers mass formula, I found that it was highly stressed so I didn't dare to draw it for the whole winter. I recenty stressed it down a bit, and retillered it once more. So this evening I finally took the camera with me, and was ready to forgive the bow if it wanted to leave this world ::) But it didn't, and it was great to shoot ;D
It draws 70# @ 28", and is 70,5" nock to nock. After perhaps 50 arrows tonight, it followed the string 0,5", measured from the back. I hope and think it will do quite well as a broadhead-flightbow, though I would have to make another string for it. The linnen string is oversized for the bow, but should be close to Mary Rose spec..

Ahh, can't wait for my 80" yew stave to get dry ;D

I've always liked the look of that stave. Great looking bow there Kviljo. I hope you'll be posting some video's soon.

Try this one:

;)
Those are 75 gram/ 1157 grain arrows by the way ;D
-
Nice work! Have you shot for distance yet. Those 75 gram arrows should be eating that bow for lunch.

Nope, but I'm hoping to angle it at 42,8 degrees soon. I'll just have to make some suitable arrows first.
They slowed it down for sure, but not as much as I would have expected.
The bow is 33mm X 30mm at the handle, and 27mm X 26mm at about midlimb, so I think it should be pretty high-performance :)
Well, that's what I hope anyway 8)
-
A new one is on its way ;)
This too is brevifolia and not as long as I would like it to be. Though some of the MR-bows are as short as this one -> 72".
Very tight rings, but the wood seems brittle, so I'm a bit sceptical. I'm aming for 80-100# somewhere between 28 and 32" though.

Very nice bowhorse kviljo. I must make one - I'm getting tired of using a spokeshave one-handed!
-
I managed without any form of wise for two years, I guess I was in such hurry to make bows that I didn't have time to make the horse. Now I can't imagine making bows without it :) Absolutely worth the effort!
-
I've only applied the measurements of bow A in "Secrets of the English war bow", so I'll have to adjust the tiller a bit.
I was a bit surpriced that the measurements gave the bow such a round tiller, and not the elliptical that we see more often.
Hoping to finish it soon, though I wont be able to shoot it for a while. Must be over 150 pounds as it is now ::)
I'm really not sure wether I should go for gold and just fine-tiller it as it is, and risk having a lot of nice firewood, or take it down under 100#.
Do you think the stave could withstand 130-150 pounds beeing only 72" long?

Hehe, I just simulated the bow in Supertiller, and it says 144 pounds at 30". 8)
If ot was 77" long, it would be 113 pounds at 30.
So I think I have decided to rather have a shootable self yew, than a almost-replica MR that might as well break.
Hopefully it will land over 100 though.

Kvijios Thats a nice looking bow. marlon

Hello Kvijo,
Sound's a wise idea, It has taked over 100 years to grow.
After all 'fools rush in where angels fear to tread'. She's going to be a real looker, though. BTW, what's 'SuperTiller'? I thought they were a 70's prog rock act?

Supertiller is a program developed by Alan Case. It's a bow simulating program. Check it out:
http://www.flightarchery.com/forum/index.php?topic=122.0
Just made a stringer for the bow, so I'm hoping to brace it now.
-
Just a little update from todays work. I've tillered it to brace and sanded it. It is 37x32mm at the center and still way too heavy ;D
Those are reindeer nocks by the way.

84# @ 20", which should translate into 151# @ 31" according to Supertiller.
Yep, I will have to take it down some more.
-
Looking good kvilijo, I cant wait to see the finish. Justin
-
Thanks :)
I've changed the tiller a bit, and that made it 65# at 20", which should progress into 120 at 30.
Do you think it will live through a 30" draw?

I like, I like, I like ! JUST THE WAY BOW IS !!!!!!! ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D....................bob
-
Hehehe ;D
It weighs 25,25 oz by the way. Over 7oz underweight according to Badgers forumla. :-\
Maybe I'll have to shave of even more ::)
-
Any progress mate?
-
Yep :)
I've taken it down some more. With 3" stringheight it is now 90# at 26". I drew it to 28" on the tiller last night, and it didn't explode ;D
So now I just need to draw it regularly some weeks, and hopefully be able to draw it fully. The tiller is also a bit more round now, like the original tiller of Bow A in Soars book. Thought that was a good idea, since it is quite short, and won't stack as much with a little more bend in the handle.
New pictures shouldn't be too far away :)
-
Kvijo, there is a modification to the long bow recomended mass procedure, every 5# over 50# you reduce the weight an additional 1%, so a 120# bow would be about 14% below the calculation, or multiply the calculation by .86. So you are really pretty close. Steve
-
I see! Thanks for the update!
Hearing that, I had to take some measures from it again :) I love this formula - it's great to be able to check how far the bow should tolerate to be drawn - before you draw it! Especially useful when dealing with these I-don't-want-to-break-bows!
With 5" stringheight it is quite exactly 90# at 26". It seems that it adds 4# between 25 and 26", so it should be 98# @ 28", or 106# @ 30", or a couple of pounds more.
It has got 1,6" stringfollow measured on the back to the wood of the tips right after drawing it to 26" and unstringing, although it had about 0,5" natural stringfollow.
It is weighing 25,25oz, which means it should be spot on at 29-30" draw. And 3,65 oz underweight at 32" and 114#.
...which at means the bow should be ready to draw at least 30" :) ...however... ;D ...I won't be able to do that without a couple of weeks of training. I haven't been shooting for a month, and I'm barely getting it to 90# @ 26" :)
-
If the bow is showing set, I don't think i would take it past 30". 2" set is not bad for a 72' bendy handle bow.
-
Alright :) I bet my ear-draw with this one won't be more than 30" anyway, hehe.
-
those are awsome hopefully illb e able to make one like that someday
-
Super bow Kviljo...love it...
-
I've been watching this bow for a long, long time. I'll bet you can't wait to get it finished! Very nice looking through all the stages.

Thanks :)
I've been a bit busy writing exams and building bows for others lately, so this one halted a bit.
Although, I have finished it a couple of times now. As soon as I seal it with bees wax, I find some spot that needs adjusting, hehe. But I think it is okay now. At least it conforms with Badgers mass formula, so it's just up to me to draw it now ;D
I'll post som pictures or a video when I'm in it 8)
-
Had a little photosession with the Osage, so I took some more pictures of this one too, plus a "full draw" ;D
I really need to start shooting regularly again, although I haven't had it back to full draw by hand before either :)

Hi, that's a fine bow Kviljo. The yew warbow has to be one of the best looking bows around.
It's 70 inches long yes? Won't there be a risk of inducing a lot of set if you draw it to 30? My very first bow was also a 'mini' english yew longbow, even shorter than yours at 60 inches! I drew it to about 27 inches and got a lot of set. The wood wasn't very well dried though.
-
It's closing in on 2" set now, with a little natural set. I've drawn it to 29" on the tiller, if I remember correctly. But I don't think I will be able to draw it much further than 30" before I have made a new and longer yew bow :)
Didn't Jaro show pictures of his 69" 90# bow beeing drawn 32"?
-
I think Jaro draws 30-31". Maybe he'll chime in.

Okay, I won't draw that far in a while anyway :)
Although I adjusted the bow slightly yesterday. Some small adjustments on the tiller, narrower tips (from 15 to 12mm) and new side-hornnocks.
I checked my weights, and now, with a 4" stringheight (measured from the back), and 2" stringfollow, it draws 85# at 27" and 91# at 28". Should be 103# at 30 when I get there some day ;)
The new sidenocks work like a dream by the way, not a sign of the string wanting to slip at all.

I like the nock Kviljo, nice and simple. How long is the taper inside it?
I've just drilled holes 2 inches long inside my nocks. Now I realise that when they are fitted, the nock to nock length of the bow will reduce by about 3 inches :( I wish I'd made the taper a bit shorter now.
JD how long do you make the holes in your nocks?
-
It goes about 5-6mm higher than the sidenock, so the wood goes just under an inch into the horn.
-
Thanks :)
I've changed the tiller a bit, and that made it 65# at 20", which should progress into 120 at 30.
Do you think it will live through a 30" draw?
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
Mediaeval and Tudor period standards for bow length were ; twice the arrow length plus two palm widths. For a short lived fiight shooting bow, one palm width less.
-
The bow survived beeing drawn 28", but I won't test it for 30" as it has followed the string enough.
