Title: 90-100lbs selfbow shortie- challenge
Post by: redhawk55 on June 16, 2016, 05:22:41 am
Has anyone ever built an about 100lbs selfbow shortie, length about 45", draw 21"-23"? No reflex or deflex, but sharp recurves.
I guess it would make 600- 800yards?
Sure this bow will not at all comfortable to shoot, maybe a shooting machine should do the job?
This is a challenge!
Anyone in?

I think you guess is wildly optimistic (but I'm quite happy to be wrong)
I'm hoping to build a flight bow soon, but I have a ton of other stuff on. I'll be happy to get over 300 yards.
Maybe if you widen the spec a tad?
a) You don't need a lower draw weight limit.
b) 48", maybe 50" max length, gives a bit more wriggle room?
c) I don't think you need a draw length limit as the bow length and weight will regulate it.
d) Clarify length... It includes any levers?
e) Dunno why you say no deflex or reflex... the other limitations surely hold it tight enough, especially if you are allowing tight recurves? (it becomes a bone of contention when does reflex become recurve?)
f) Anyone who builds one is allowed a beer :laugh:.

Not trying to steal your thunder, just trying to open it out to get more participants :)
I'll have my lawyers draw up something ;)

Id be more inclined if I could reflex or deflex as I see fit.

  I built a 42" ipe self bow one time that drew some amount over 100# estimate about 130# but only drew it 18". I mounted it on a board and shot it like a crossbow. I think what you describe is very doable and may have been done by the old flight shooters in the early 20th century.

The  selfbows shot as footbows in the early 20th century achieved around half a mile or more but they drew a much heavier weight.
  One of them that pulled 225 pounds was still described as '"little".

Cat.......................if my wife will scent out this post, there will be trouble in paradise...................what about your bow-classes, what about the new garden fence...........etc..............

Yes, I' m wildly optimistic and curious. I had been heavily busy with the enlargement of my workshop. To rebuild an old stinking pig's barn for about 3 months makes you longing for some great new challenges.

I' m just curious if a short selfbow with a drawweight of 80lbs plus has ever been built.
Steve, have you ever measured speed and distance of that ipe- selfbow? What is known about these heavy flightbows of the flightshooters of the early 20th century?

The design I described is just my favourite design for flights and I guess it is the best design for such a bow.

I would suggest the length and drawweight only as a limit: 50", 80lbs plus, everything other is up to the bowyer.

O.k., one beer, cheers, Michael

  Michael, I didn't get an accurate measure but I think it was close to about 400 yards.   I was using a cut off target arrow with 5" fletches.

loon, it is made by Simpson?
Yes this bow would be a candidate if it would be shorter. Anyway 56" drawn to 28" !!!!
I guess this bow to be to heavy for a record shot?

  I think that bow could make a serious contender.

This guy is 65# and pulled to 27 ish ( i cant remember exactly ). As i recall its 48 inches ntn. I could make a heavier one but what exactly is the goal?

The goal is long distance and lots of it

When i get the chance i will make one and send it to you if you want to test it to that purpose? I dont have the room.

What, and you think I do?  If you make the bow and want to send it to someone then send it to Steve.

I'm sure Steve would be able to find someone to shoot it at the flats
Title: Re: 90-100lbs selfbow shortie- challenge
Post by: Badger on July 21, 2016, 01:59:30 pm
  This year might be my last year, but as a rule bows can usually find a shooter at the flats, maybe not 100% sure but by joining the flight page you can usually connect with a shooter. What they will do is shoot the bow in practice and if they get off good shots will use it in the tournament. Sometimes a bow may be very fast but for some reason a shooter may be getting better distance from another bow because of arrow flight. So not always a guarantee your bow will get shot.

Such a bow, being 45" long and so heavy a draw, with finger pinch ( not terrible at 65 but with high weight may be worse ) is it likely to be shot at all? Maybe an 80# would be better or are there folks who shoot those horn bows that may be interested in shooting? Is there a horn bow class?
Title: Re: 90-100lbs selfbow shortie- challenge
Post by: Badger on July 21, 2016, 02:12:21 pm
Complex composite is our horn bow class but no need to shoot it in other classes if it is as selfbow.
Title: Re: 90-100lbs selfbow shortie- challenge
Post by: sleek on July 21, 2016, 02:13:37 pm
I understand.  I just need someone who can shoot this short a bow that heavy and pull it that far back.
Title: Re: 90-100lbs selfbow shortie- challenge
Post by: sleek on July 21, 2016, 02:20:31 pm
Do you think this type bow would do any good in a flight shoot?

I assume there is also a sinew backed class? I already have a self bow made i just need to sinew back it due to a crack on the back. I have shot it plenty with that crack but am going to back it anyway. Its 65# right now, a few layers of sinew should get me 80#, I hope. I could reflex the limbs to get string tension up too.... any thoughts on this?

Easy solution to that finger pinch, thumb ring...

  If the bow took some set after building which most short bows do I doubt it would be very good. You never know unless you try though.

How much set would be the most you would consider before saying its not worth it?
Title: Re: 90-100lbs selfbow shortie- challenge
Post by: Badger on July 22, 2016, 05:02:54 pm
  I knoiw a lot of guys post that a bow shows one profile after shooting but quickly recovers. I prefer a bow with no recovery, sometimes bows can loose a little of their profile but not really be damaged. If they show recovery after they sit it is more a sign of damage. So guess my answer is I want a bow with the same profile just unstrung as it will be an hour later.
Title: Re: 90-100lbs selfbow shortie- challenge
Post by: sleek on July 22, 2016, 05:20:05 pm
Wow. I would have never thought about the recovery implicatuons that way. Makes perfect sense. Thanks.

Hi fellow flight shooters!

Im recently found my self interested in flight shooting and building shorties under 52" with 20-23" draw length. I happen to have plenty of this "superwood" as we tend to call it, syringa vulgaris (also "lilac"?"). Sg rating of about .80 and really elastic. I have made couple of shorties from not-so-perfect staves and the wood really is capable of amazing compression and high pound bows.
For example, 51" selfbow recurve of syringa, 20" draw 48#, and holds 2" reflex immediately after taken off brace.
And the bow i shot my own rookie record (231 yards) on my second flyshoot meeting, 50" selfbow syringa, 22" draw 68# and holds 3/4" reflex immediately after taken of brace. And this stave was on 1" natural deflex!!
What i have found out has been that, even though the wood is really dense, it really benefits from heat treating. I would estimate 10-15 pounds difference in these shortbows for example.
Those two bows that i introduced were about 1 5/8" wide, with circular tiller.

I am by no means that experienced bowyer yet, but interested in learning, so im planning to make some really heavy shorties from syringa. Its really gnarly and knotty wood so you tend to get really short pieces out of it. But i also happen to have one about 70" piece of it.

That 231 yards with 68# syringa, was by no means good result, cause my whole flight shooting equipment (bow and arrows) were made on the same week of the competition. Which included panic with arrow spine and last resort cutting arrows shorter with pocket knife near the starting line.

Is it so that this kind of 45-50" bow would be capable to compete at really those long distances? Why dont you see these 70++ pound bows as shorties then more often?
If its true, im really looking forward at letting loose of arrows from my future ~100 pound syringa shorties ;)!!
