Title: Early draw weight question
Post by: snowplow on September 17, 2014, 03:41:00 PM
So as I look into eastern vs western recurves, I notice that much of the eastern stuff looks like this unstrung:

So does this generally make a faster bow? Seems like it should. Are there western recurves like this too?

I'm sure a wise soul will know the answer. My guess is in ancient times the design was dictated by the materials and I know they used a lot of horn in their bows.

If they were faster we'd all be shooting them.

I don't believe there is any real testing to support the idea that eastern bows are faster-just thinking about stringing them gives me a groin pull-but to each his own.
If you are interested in speeds Blacky Schwartz runs a web site that compares bows of various makes.

This doesn't really have anything to do with eastern bows perse, that's just the only ones that I have seen with this trait.

Take 2 50# bows. One is 25# at brace and the other is 1# at brace. Both are 50# @ 28".

Would one be faster than the other?

Seems like the one with the higher brace poundage should be to me.

Similarly, take 2 50# bows. One is 50# at 20" and the other is 50# @ 30". Both are the same weight at brace. Would one be faster?

It seems like the longer draw should be.

It seems like there should be a poundage per inch correlation. Is there anything to this?

Snowplow,

I was going to post to your other thread, but can't find it at the moment.  When I recommended going to a bow with a "smoother" force draw curve, I meant "if you go heavier in draw weight."

Although I may be wrong, and there is no science (that I'm aware of) to support it, I have seen that most bows that stack pounds early seem to shoot a bit faster and "hit harder" than the smoother" ones that add poundage later.  This has been my GENERAL observation anyway...

In your quest for a faster bow, you should also look at the limb length.  It is proven that, all else being equal, a bow with shorter limbs is faster.  If you are concerned about losing accuracy, you can get one with a longer riser.  They don't look as cool IMO, but they offer a good balance of speed and accuracy.  Worth looking into.  

You can also experiment with carbon arrows to find something stiff enough, but lighter in weight.  I just started using them, but find them overall less forgiving of different draw weights than aluminum.

Skinny strings generally help too.

I also believe that most bows with reputations that put them in the top 5 percent speed-wise, are not really built to last as long.  After all, would you expect to get 200,000 miles on a formula-one race car?

Others may say I'm wrong, but that has been my experience.  Good luck in your quest.  Figuring out what works best for you is half the fun.

Thanks John. I am having a good time looking into this stuff.
