Be gentle with me guys, this is my first try at a Deflexed Recurve RD, DR whatever... It's only the second time I've used Elder (It's Monkey bow's big brother ;D ).
I didn't really have any idea what I was doing so it was all done on the fly by the seat of my pants, aiming for something round 60 -70# at 26" ish ;)
The digital scale read 69# at 26"
She's 66" ntn in a straight line (and about 25,000 miles if you measure the long way round the the back or the world ;) )
I think I've got too much bend near the grip and the left (lower limb is prob' a tad straight compared with the upper).
Critique will be appreciated as it's my first.
I was after a fast bow to beat my speed record... not tried it get as I haven't made the string. She's heavy to draw as 70# at 26" makes my poor ageing shoulders think "Hey Del you ain't getting this baby back to 28" !
Tips could prob loose some weight. Tip overlays are Laburnum. The belly side of the grip needs building up with cork to be comfortable. I filled the pith groove in the grip with some Yew offcuts... more pics if you ask nicely ::)
You can see see my new Ali' toroidal string adjuster too :)

Take it for what it's worth as I've never even attempted a r/d, but it looks good to me.

Elder is a great wood.
Sorry no input on tiller as I have never made a full on DR but the resting profile says nawt is hurting ??
-
Looks ok for the first one.
Could bend a little more in the outer limbs and a little less near the handle as you said.
Maybe a little heattreat at the fade outs and some scraping at the outer limbs and you can pull her to 28"

She's had the heat treatment! Several times... and some steaming to get the deflex :)
Mind I can ease her off a tad as I could afford to loose say 5#

No expert for sure ,but looks good to me,maybe a bit much at the handle /fad area but the rest looks fine. All the reflex and tip area has flattened out nice to my eyes. :)

Looks great to me, but I have never made a RD bow.

I definatley wouldn't try to get the outer limbs bending any more. Over all if say you did great for your first go at it! I bet it's SMOOTH!

Dunno... I haven't pulled it right back yet ;).
Actually its a tad scarey, I can feel a hint of flex in the grip.... although she's been back a bit past 26" on the tiller.
Just finished the string... I'll give it a go once I've had a bite to eat.

The left limb does appear to be slightly stiffer . . . but it is looking pretty darned good. Looking forward to viewing the final product!!

It's a damned good thing I didn't let a certain Cat bow look at the computer this morning ::) Nicely done though. Don't know squat about those bows but do know about trying to make the profiles match. Looks to me that if you insist on the very last little symmetry thing maybe a couple scrapes left mid-limb to flatten the fade a smidge.
No matter what, I like my English long bow best 8)

Pretty cool bow :)
I'd say the right limb is bending a little too much near the fades. It's the mid limb that needs a little tweaking to my eyes.
-
What is the width taper like?

About 2" at widest, here's a pic of me inspecting the bottom nock.

Like a hint more bend in mid limb?

Thats a good job Del, not easy to get that kind of weight from that design at that length.

Cheers ;D
Errrr, I think I maybe need to move it to the warbow section! >:D
I just struggled to shoot a few of my 11/32" shafted arrows and it rang like a bell, and the brace dropped about 1/4"
I twisted up the string and shot some of my 3/8" heavy weight 32" 763 grain arrows.
I got the right elbow high and came over and down warbow style but to anchor front of my chin, much easier and smoother.
Whoooomp... straight as ... well an arrow ::) and it rocked the boss backwards. I think it's maybe as fast and hard as the 100# Elm warbow.
I'll try and rig up the chrono if I can avoid shooting it!

DAMN!
I got the chono all set up with the lighting better...
Got.
it..
to...
FulldrawandBANG... :o
But it's a very good quality break ::) shows the limbs were nice and evenly stressed. Big split ran right through the handle and pinched my finger!
Shame it never shot through the chrono.... :-[ :'(
Makes me wonder if I over drew slightly, maybe went towards my normal full draw??
Still, at least I got the pics and shot a few arrows.
Gives me an idea of how far to push it next time.
Gotta look on the bright side, at least I don't have to do all that finishing ;) ;D
Del
@ At WillH... yeah, smooth until the nasty BANG >:D

Commiserations Dell. Lived fast died young.

Bummer..........

Very nearly moved to tears for you here brother! I mean we all know these things happen, ...but we never quite get used to them! Sassarasafrassa sufferen succatash!

... I don't s'pose you want to see the tip overlays now? :laugh:
Just looked at the breaks, the back gave way just inboard of mid limb.
Gotta get me some more Elder now, that bit was a fallen bit I picked up on the cycle track.

Looks like Monkey bow has the last laugh oooh oooh Aaaah aaaah aaaah!

Perhaps it's name, "Elder Statesman", was it's downfall as politicians are all about broken promises... ;)
It sure looked great while it lasted tho Del.

lmbo ^^^^ this!!

Del, I seem to limit out around 60# on those type bows unless I make them considerably wider which I haven't done yet. Osage might be better wood to try that same design again.

Cheers, yeah, I think I got a bit carried away and greedy, but it was sort of experimental.
I'll have a lot better idea what I'm doing next time (e.g. more than zero ;) )
Maybe 60 @28" from a slightly longer bow, bit more reflex and a more carefully worked out reflex.
Starting out with a better bit of timber would have helped, I had a good bit of twist, knots and a ridge along the back the cope with.
Mind I blame it all on the FF string ;) >:D (joke... guys... its a joke....)

Ohh my, I can hear sad bad sound Del.
But as you said a good experiment and I believe its possible. Would be interesting where the crack did start.
My thoughts on string:
FF is a wide range of materials with very different pros and cons.
For me, I'm convinced the BCY 452X is best for wooden bows, because its a mixture of vectran and dynema and still is a bit stretchy with no creep. I never do pure dynema materials for my strings. Just my 2 cents.
Forgot to say, I use 6 strands up to 70pounders, and 4 strands up to 40. when you use more strands, you loose the stretch.
-
Hi, yeah, the string was 10 strands of Astro Flight... I was just kidding about the string really, I don't think it was a contributory factor. I just hear so many people on another forum talking about FF bing bad for logbows, which is nonsense IMO.
I have a suspicion, I was too busy lining up with the chrono, I might have drawn to 28" ::). Anyhow, I learned a good bit from it, and it's good to try new stuff.
I think the break was about 1/3 to 1/2 way along the limbs out from the grip on the back, looks like they both blew together. It was certainly spectacular!

Don't you wish you'd had the slow-motion camera setup and watching that one!?

"Elder Statesman" .... may he rest in peace.
I have had a few blow up in my hand like that - never quite get used to it. Good luck on the next one.
-
It was a damn fine first run, Del. I'm sure you'll get it, buddy.
-
Good quality break, ;D ;D I will have to remember that one. :) to bad,I thought it was looking pretty good,shows what I know. ;) :)

Well that's to bad del. nice break though! Go build you another, you got it now :)

Hi, Yes, I have a piece of Laburnum with some natural deflex, might do the job. It's tough stuff I made a primitive cross bow with it 80# from a V short bow.
I might start marking it out tonight if it's long enough :)
