so what are your opinions on this subject,was reading in the bowyers bible design chapter symetrical is best but i see a lot of posts showing upper limbs longer than lower so WHAT ACTUALLY IS BEST??would be interested to see what your opinions are??
-
I started the popcorn for this one....:)
I guess I'll start: I have made many both ways. Seems to me that on straight limbed/straight forward,no nonsence self bows,A shorter bottom limb handles,and just feels better in the hand upon release.(at least to me)
On recurves or on bows with flipped tips,symmetrical limbs handle better. I rack my brain trying figure it all out, and have never came up with solid proof to justify saying one way or another. ie/ all things being equal, (as we all know they are not)
One thing overlooked by many is limb timing,regardless of how you lay out your limbs, push yourself to get them even.For those just starting out, I would advise symmetrical limbs and as their experience advances, build some with asymmetrical limbs. It's how we learn.
I can tell you that the best shooting bow I have is a straight limbed 58" with a 1" shorter bottom limb.
Open the gates boys!:)

I used to make asymmetrical bows but now I build them symmetrical. Makes seeing tillering easier for me. I think either way works fine.
Tim, I like butter and a little cayenne! ;)
-
I make mine symetrical. The math is easier on the symetrical kind. And that is all I have to say on the matter. :-X
-
I make em Both Ways...aint neither one my Favorite....and I hate Popcorn...of any kind........... :P
-
The last bow I finished was a take down straight limbed bow that the bottom limb was one inch shorter than the top limb. I tried to tiller it on my tree but I never could see the tiller correctly... I ended up tillering it with a mirror and drawing it by hand... It shoots great though.. But so do my symmetrical bows... ???
I like Oriville Redenbockers pour over cheddar popcorn, you know the kind that has the liquid cheese packet? If you haven't tried it I highly reccomend it guys. ;) -josh

I've found that I can break both symmetrical and non-symmetrical bows.
Popcorn? How about beer and oreos. Yum!
-
My Strongest and most Accurate Bow that I have ever built is an Asymtemtrical Osage Bow...with the Bottom Limb being two inches shorter than the Top....Full Draw Pictures look different...but man that Puppy can toss an Arrow!!
Don't care for Beer either....but I sure like Bourbon....and....Nutter Nuttter Butter Peanut Butter Sandwich Cookies....but not necessarily together.... ;D

The Breakfast of Champions ;D
Never tried asymetrical, but isn't that done to compensate for nocking the arrow above center?
-
Asymetrical bows balance nicer in the hand when carrying them - that's the only reason I build them that way.
-
Every asymetrical limbed bow I ever made ended up with more set on the upper limb than the shorter lower limb which seems odd.... I prefer symetrical limbs myself.
-
Been building them both ways, with good results both ways. Seems to me though that if my asymetrical has slightly stiffer bottom limb it shoots better, and on my symetrical bows if I keep the top limb slightly stiffer, seems better. I am probably wrong, but what the heck, I'm having fun.
-
Dave, usualy you would want the lower limb to be stiffer on a symetrical bow and the limbs to be evenly tillered on a asymetrical bow.
That does sound strange.
-
Primarily symmetrical on straight bows, but non straight bow wood where the arrow shoots best is where the mark goes..
-
Generally assymetrical since I make a lot of elbs.
Zenmonkeyman, beer and oreos together? Do you dunk 'em?
-
What about two fingers below and one above? Is asymmetry supposed to work better with the extra pull below the arrow?
Hrothgar, I've never dunked them. And I know it's an odd-sounding choice, but it's one of those great combos like wine & cheese, strawberries & champagne, or surf & turf. You have to try it to believe it.

Hi guys,
I've read the entire thread a couple of times and I'm confused... (I know, since the 2nd grade...)
Japanese bows are very unbalance for limb length, and they use a thumb hook to draw with.
My lack of understanding, is what is the advandage of a longer upper limb?
It it just a form of positive tiller accomplished differently than a stronger lower limb?
Any discussion would help me quite a bit.
OOPs, almost forgot..... My vote goes for buttered popcorn....
Instead, of course, you can always dunk me in beer and throw me to the drunk chicks......(Much More Fun!!)
Thanks
Steve

Doctor said I have to cut back on the junk food so here goes nothing!
Mox, handle off set or longer/shorter limb is dependent on one's hand placement/grip, nothing more, nothing less. Design a bow for the way you grip 'em or grip a bow the way it was designed.
Still can't understand why the glass folks got all this stuff figured out and the selfbow community is still struggling with it. Like limb length, arrow pass/shelf placement and positive tiller. ART

Reply to Eric,
Thanks for the PM.
I found your information quite helpful.
In the case of the uber long upper limbed Japanese bows, I thought that the reason might have been that it facilitated better control while on horseback.
Your discussion makes more sense and fills in a lot of gaps in my understanding.
Thanks,
PS, sorry for the delay in responding to you.
I seem to be having trouble with my profile. The personal message box is missing.
I had to find your PM in my personal email account.
Take Care,
Steve
