I built this 50#er. Did not end up like I wanted exactly but it will more than likely break a broadhead record.
-
very nice Arvin and good luck!
looks like an ode to the pyramid-design.
I'd love to once work a clean and straight piece of osage like that.
cheers

I'm looking forward to seeing just how far it shoots Arvin. So... you will beat your own 239 yards 1 foot and 11 inch record. (SH) :OK

Cool bow!
-
Sweet bow, hope ya crush that record
-
Nice! That profile is my favorite. Great job and good luck with it
-
Very nice bow Arvin. Hope it's another winner for you. Best of luck with the flight competition.

Arvin - your grass is too perfect!

Astro turf . No need to mow but getting small leaves off of it is a pain.

Nice looking bow Arvin. I’m curious as to what didn’t turn out like what you wanted? What would you change and why?
-
Very nice Arvin! What made it so special? No set??
-
Will you nock it off Arvin? I'm over here constantly designing and crunching numbers on how to break your record with my short bow, and you keep moving the dang goal post!
That bow looks amazing and I don't see any set in the spots you have struggled with in the past. I'd like to see you shoot that one in flight as well.

No Steve it took about 1” of set. Thru out the length of the limbs. Not sure what that means? It broke down thru the entire bow I guess. Lots of stress in this design. It has good cast . Never pulled it over about 47# till I got 26-27”. I got it to about 47@27 then pulled it to 50@28. I have one that broke and I glued it back together it shoots a tad farther. We will see what they do in September.

I would like to have had some back set it the handle not a lot just a 1/2 “ or so. This wood took heat but was contrary about it.

Sleek I’ll test it in flight but this design does not do so good in flight so far. Comes up 20-30 yards short.
-
Would like to see you make one from a good piece of hickory, and elm, and black locust.

I REALLY shouldn't say this if I wanna keep my record buuutt..... 20 to 30 yards ain't nothin. That's just one good arrow and a perfect release away from breaking my record.

Nice looking bow Arvin.
I’m always telling my wife I want to get Astro turf.

Thanks guys for the kind words.i got this bow in the mail today. No string though. Maybe I can get Pat to help me build a string for it get it strung and test it at the Classic. I’m curious to see how the crab bows compare to selfbows in broadhead ?

Yes I think you are right with that wide pyramid it might be a good combo. I don’t have any good wide flat back dry hickory though. Maybe some one could try that. Interesting.

Arvin. Glad to see it arrived ok and in one piece. The test string I used for this bow was from another horn bow actually and was b55. Your d97 string material would be better for your testing for sure. I can send the test string in the mail if you like???

Just loop size and length would work fine.

Just loop size and length would work fine.
The string I used for testing was 60 1/2” long with 1 1/2-2” loops would work. You could go with just a 60 1/4” even and play with your length of loops. The strings saddles will accommodate much larger loops too. Let me know and I can send off this test string in the mail. It’s not a great sting but will work. I was gonna make a proper string for it with my endless loop jig but I figured you’d want a d97 string for your testing so I didn’t bother. Use the custom stringer I sent when you do string it up. There’s a good 13” of reflex in that thing. I posted the short vid for you on the build towards the end to show the stringing it up. Keep in touch.
Cheers.

Thanks Dave that should be enough info. What kind of brace ht ? from belly side of handle? Thanks again it’s a beauty.

I should have written that down. If I recall is was about 5.75-6” from the belly horn lam at deepest point to the string. That is what I used for testing anyway. Horn bows don’t usually have handle like this that fade/tapers inward like this bow does. That’s why I measured from the belly lam at deepest point. Play around with this as you may find the brace the works for you. I don’t mind a lower then normal brace personally as it gives me a longer power stroke I find. The main disadvantage is a little wrist slap but nothing significant.
I had some issues initially with getting consistent readings on my chrono the first day but following day I was able to get more consistent reading in low 180’s fps with a 400 and 450grain arrow. That was with the test string of b55. Mid 180’s readings using a lighter arrow. Warm it up a bit by exercising the limbs and spend some time getting it balanced before shooting right away as it will perform better too and even out the bend nice on the limbs. These all natural bows with horn and sinew take some initial care to get ready to shoot but worth the little extra time and work. I put about 150-200 arrows through this bow and then cleaned it up and put several coats of true oil. You’ll mark up the arrow pass a bit when shooting so You could put a small piece of material there to protect the finish if concerned about it. Hope you enjoy it my friend.
