Hi All
I'm happy to post a few pics about my new hornbow. Didn't know weather I should call it primitive Hornbow or advanced Selfbow ;)
Drawweight is just perfect to me - the originally 52# really felt uncomfortable to handle. It's 61" measured over the back. After resting the bow has a 11" reflex and after shooting around 8" (measured from the nocks). It's shot in well by now. A friend gave me a set of matching arrows too - didn't know how straight arrows can fly; my handicap just improved 50% since (-S
Specs:
Ash core
Buffalo Horn
Buffalo Nocks
Beef Backstrap
Rawhide
Laburnum arrowpass
620 gramms
8 strands of bcy452x
Cheers

Very nice and i'm glad it worked out well for you.
Love the labernum arrowpass too :)
-
Wow, Thats pretty cool! :)
-
That's a nice primitive bow (-S
-
Very cool bow and a nice upgrade. :OK
-
Which glue did you use for the horn wood gluing?
For the tendons and the rawhide you certainly used hide glue. For the horn plates too?
-
thanx for nice comments dudes. glad you like it.
Andrew: this time I was too lazy to glue the horns with the hide glue stuff and used some of the expensive epoxy instead (-S

Very cool bow

How did you prepare the surface for epoxy, and what epoxy did you use?
-
thanx del 🙃
sleek: i do groove both sides well with a metal saw blade, brush them clean and glue with uhu 300 plus. but there sure are equivalent glues on the market i think. this one just has good reputation around here, is easy to work and can deal withe higher temperatures needed for heat corrections, manual says you can temper it @ 180 degree celsius👍
-
Sleek EA40 works perfectly as well. Mix it 2:1 and you have the required resistance to heat. Flat surfaces are fine, sanded to anywhere between 120 and 60 grit.

interesting bownarra, so many people, so many approaches ;)
-
That's a beauty. I've still got two pieces of horn.
-
:OK

yes many ways to skin the proverbial....
I've never used it on a full sized bow but this is the way I make the 1/2 size mini hornbows. They are great fun and allow you to try ideas out with bits of waste materials.
-
Great job Simon !!
Love the look, how is this design called? Yrtzi bows or something like that, right?
Greets from pinzgau!
-
Thanx DC! You will do that hornbow after you broke that record ;D looking forward!
Thanx willie!
Bownarra: I just groove because I think it's a simple and very effective way to strengthen any glueline and in that case because the glueing of the horns to me seems the most critical part of the build. I also groove critical wood laminations, because its so easy and gives a good feeling ;D Those 1/2 size mini hornbow are fun sure - do you shoot them in the living room? ;D
Martin: This design just happend to me when I started doing Moellegabets with reflexed levers in the 13/17 ratio in 2018. So I claim this specific design for myself. I did it as selfbows, sinewbacked and then hornbows. The ones I did for you are out of this series too. I later found out, that Yrtzis and Mongolians are similar indeed but I never really examined them and can't say what the differences may are...
Cheers

That's an amazing design, and it looks great to! It reminds me of the composite longbow mentioned in the chapter Design and Performance Revisited in TTB 4. Now if only I could get some good horn ...
-
As if I dont have enough to do, you have given me another project....
-
By the way, is that American Bison or Water Buffalo Horn? Did you cut the strip out in a spiral or straight off the outside of the curve?
Thanks,
-
thanks tradcraftsman, i will check that out in tbb4 ;D its the outsides of water buffalo horns.
sorry sleek, I do apoligize 😁
-
woweee, that is amazing, how does it shoot compared to your self and sinew backed models?
-
Rakau: 1.2.3. Hornbow 4. Selfbow 5. Sinew Backed
If I had heated reflex in before sinewing this one probably ended 4th place...it's a learning process...reflex and string tension seems to be the key. cheers
i will do more of them. it's intetesting to stay at the same design for a while. will do another elm (,it sadly broke when overdrawing) and would like to check out black locust and ash also 😁 always busy with projects 🤪
-
Very cool bow! Great work!
-
If you want to get more performance tiller the horn version to have a more abrupt bend right out of the fades. This will give a longer return path and store more energy. :)
-
that's a good point bownarra :OK that was the plan - already with this one - but it's not so easy to properly hinge a bow - still learning ;D
the hinge will also help for good string tension, wouldn't't it?
-
The amount of string tension is more related to the amount of just un-braced reflex you hold.
-
thanx for enlightment bownarra (-S
-
Hey, sweet bow sink!
-
Nicely done. I wonder how far,and fast it would shoot that arrow ?
-
Very nice. This appears to be a mild composite, that is a mildly reflexed sinew wood horn composite bow. "Advanced selfbow" is a little misleading and sounds pretentious. It is not quite a selfbow, but a backed bow or a laminated bow if just horn is added to wood. If Moellegabet bows are advanced. how about deflex-reflexed recurves?
I am fascinated by the design and wondering why that extreme ratio of 13/17 is adopted. The working limbs do not appear to be particularly wide enough for such ratio. I would really appreciate the full spec and some FPS numbers. Thanks.
