Arvin is one of the guys I would really love to stand in a big field and watch arrows sail through the air with. Maybe even watch them just plain disappear.
He has been more than generous with me over the years and sent me several really nice pieces of Osage .
Last summer I got home one night to find a nice package. Even my wife was excited to see what was inside.
I opened it up to find two bow blanks.
One a pyramid design with a light reflex in the tips.
The other a little wiggly with reflex through the whole bow
Arvin wanted me to make a 48 lb @ 25” for flight bow.
He even sent me some arrows
I told him it would probably be after Christmas before I got at it.
I picked up the pyramid one with the slightly reflexed tips and ran my finger caliper over it. I was really impressed. I could tell there wasn’t going to be much that wasn’t a bow there.
I shaped the tips and made a string.
I think I made about the same amount of shavings and dust reduce the tips and shaping the handle as I did tillering .
I got it to 48@24”

Nice BJ, just like you said about Damon's , it looks much better here. :)

Agree with Pappy 100%

How long is the bow? Did it take any set?
-
🤠

Sorry I thought I replied to Sleek but I don’t see my reply here. Maybe I missed the post button.
Sleek I think it’s 62” if I remember correctly.
It did take about a 1/4” of set
I did take a couple scraps off the outer third on right limb, sanded and put two coats of Tung oil on. I haven’t had a chance to put it on tree since.
I’m hoping to get a force draw done for Arvin but I haven’t been able to find the time.
This cold weather is making me lots of extra work.

Nice work BJ! I always admired the skinny tips on your bows.
-
sweet lookin bend on this bow bj
-
You guys need to stay tuned to this bow.
-
Well Arvin n me are going to do some testing with this one when we get a chance.
I did shoot one of the flight arrows bare shaft into my black hole target and it seemed to have pretty good arrow flight. I know very little about flight arrows but enough to know they are completely different than hunting arrows.
Arvin asked if I could do a force draw curve. I did my best. First time I ever did one. I just have a fishing scale so it’s not as precise as it could be but it’s pretty close I think.
Arvin seemed pretty happy with the numbers.
Can’t wait to get in a big field and send a couple down range

thanks BJ and Arvin...this is going to just keep getting better... :OK
-
Nice
-
Very nice bend on this pyramid, Brian. :OK
-
If the scale is close to accurate the bow has high early draw weight. Notice the unstrung profile. The tip s are out front of the handle . This is why the bow has high early draw weight. The fact that BJ finished the bow with very little set contributes to the high early draw weight. He can tiller a bow !!!! I look forward to him giving me some tillering tips. This could be one to break records. Lots of energy in 16-17” of draw from brace!
-
Thanks Arvin I really don’t have any idea if it’s a record holder.
I like early string tension for my short draw bows. I don’t have numbers, but they always seem to perform well with my short draw. I’ve always wondered how “Simply Orange “ would do. That bow fits me perfectly and it has been hunted with and carried around by me for about 8 years now. It’s really held its profile amazingly well.
I look forward to learning more about flight. I have lots of places I can shoot an arrow for distance when it warms up a little. I’ve shot my target arrows playing around but never really even
measured distance. Should be good fun with the grandkids. We like shooting holes in the sky.
And I can get them to retrieve the arrow while I range them with my range finder.

As Arvin sez, the force draw numbers look impressive.
Is it a true prymid? Can you post a pic of the back?
-
Willie I would call it a true pyramid design. I need to get some pictures taken. Maybe I can get some tomorrow.
Bjrogg
-
Willie , I got a couple pictures for you. I’m not an expert in identifying different styles of bows, but I would call this a pyramid.
The back is very flat. Beautiful piece of wood. It has about a 1 1/2 reflex if I remember correctly but I don’t know if it would be considered a recurve. I don’t think the string touch’s the belly but I could be wrong.
Bjrogg

Arvin has sent me at least Three pieces of Osage.
I have made bows from two of them so far.
The first one I made is in the middle. It came from a beautiful stave I almost ruined by trying to split off the belly.
I ended up ruining the top of my stave and being stuck with only the belly split. Lesson learned. This really thin early wood with thick late wood rings splits different than any I’ve split before.
I did manage to get a very nice good performance bow from it. I called it Flats or Bust hoping to get to the flats with it.
It’s more of what I would call a flat bow. Honestly I didn’t measure anything but the length, reflex and handle. I laid it out with my draw knife and followed the grain, then tapered the last nine inches to the tips. It has short but fairly aggressive recurve tips. I don’t have a chronograph but I think it is pretty fast. I think it’s about three inches longer than Arvin n Me but it has just shy of three inches of reflex and it’s been holding it good.
Arvin n Me on the left, Flat or Bust center and a blank I haven’t started yet on the right

Try to show different amounts and placement of reflex

I am so glad this forum was resurrected even if just to watch this bromance between bj and Arvin bloom! It's like a freaking Hallmark Channel movie in real life and real time! Please tell me one of you recently moved back to their old home town and opened a coffee shop or bakery.
-
I can’t speak for Arvin, but I moved back to my home town over 45 years ago. Never started a coffee shop, but my son does have a shop a bunch of us old timers have coffee at every Saturday morning.
It sure is a good thing to keep the site JW
Thanks

Keep posting the excellent content and don't let me get too far under your skin!
-
My skin’s fairly thick JW. Dig away.
I decided to do a force draw curve for the first bow I made from the stave Arvin sent me. The stats are just slightly different for Flats or Bust.
Its 45@ 25
About 3” longer and almost two more inches of reflex.
Bjrogg
PS once again I am using a fishing scale. It’s not digital
-
nice bows brian, thanks for the pics.
would you be willing to take a few more measurements of "Arvin and Me" so that I can reference the data for the stave that Arvin is tillering for the computer design?
If so from what I have seen so far in the thread it is
62" ntn with 1/4 " set prymid
but I didnt see how wide at the fades
and if you could mike some thicknesses at four inch intervals out the limb from center that would be great.
-
Willie I did some more measuring for you.
The length is 62” n-n
I would say it is closer to 1/2” set now.
Handle and fades I would say 10”
Out of fade 1.595”
Tip 1/2”
The reflex is 1 1/4”
Hope that helps. Let me know if you need more
Bjrogg
-
the extra info and pic are appreciated.
do you have a caliper to make some limb thickness measurements with?
every four inches would be adequate
thanks
-
I will try to get that for you tomorrow if I can.
The back is very flat.
The belly was almost what I think you would call trapped?
When I tillered I removed the peak of the trap.
If I remember correctly there is still a trapped edge over most of the working limb.

Bjrogg
did you flatten the back or were the rings that way when you got it?
-
The back was naturally flat. It already had the ring chased and sealed. I didn’t touch it
Bjrogg

Willie I posted width at fade wrong previously. I corrected it now. I’m going to get you some better measurements
Out of fade was 1.595”
Working on it now
Bjrogg
-
Willie I must have been holding the dummy end of the tape before. I didn’t think it was 2” wide
I used calipers now. I measured at thickness and width at fade and then @ 4,8,12,16,20,24”
I did top and bottom limb
Bjrogg
Ps hope you can read my children scratching
-
I missed a line first picture i fixed it
-
looks good,thanks I will plot it in the other thread. It is nice to have real life examples when making comparisions with the program. Conventional widsom says every stave is different, and that could be more true if you were to buy a red oak board at the lumberyard where you are, and I were to do the same here.
And less true when a bowyer like Arvin is hand picking the best.
-
Arvin and I finally got together and got to shoot a few arrows. We didn’t have a field we could use but we shot a few arrows through the crono. Unfortunately it wasn’t sunny enough to get a reading.
Going to leave this bow with Arvin when I head home.
The full draw looks pretty good yet and we don’t seem to be picking up any more set. The force draw is still holding up to.
Bjrogg
-
Thanks for the great picture BJ. Nice form Arvin and the full draw looks spot on. :OK
-
How much set did it pick up?
-
Sleek it started out with 1 3/4” reflex and it seems to be holding 1 1/4” reflex
So it took about 1/2” of set. We put it on Arvins tree and compared force draw before and after we shot it several times through crono (unfortunately couldn’t get reading) and drew it and held it to full draw on tree and it held its same force draw.
I’m not a numbers guy but Arvin thinks it might be a competitive bow. I’m leaving it with him. It’s his winner or loser. It’s certainly a nice bow one way or the other.
Hopefully I can get to the flats someday with him.

Did any of that 1/2" come back after being unstrung?
-
That 1/2” is difference from what I started with before any bending and what it has now. It might have a 1/4” immediately after unstrung that comes back

Bjrogg
So 1/4 is set, the other 1/4 is likely reflex that pulled out. That's damn good. Is this a bow i ran numbers on for you guys to check its surface area as draw weight?

Sorry I can’t tell you that Sleek but I did put the measurements every four inches of both width and thickness. It’s posted on this thread. There are two different bows that I gave dimensions for.
It would be the first one (Arvin n Me)
