Title: String Loop Q
Post by: simk on February 05, 2020, 02:09:13 am
Hi All

I was just wondering, if biiig string loops improve stability of a highly reflexed/recurved bow ? - weather they are better than tiny loops?

I have the feeling that they do and also have seen biiig loops on some asiatic hornbows...

What do you think?

Thank you for your thoughts!

Cheers

The loop size on hornbows is because  of the sityah shape.   So any stability would be due to that rather than just the fact that the loops are large. The loop has to straddle the wedge shape or teardrop profile.

Thank you very much PatM for your contribution!

The huge string loops I saw on these hornbows were much larger than actually needed to pass the levers...

I then today also put this same question to my personal consultant which clearly confirmed my assumption. I unfortunately didn't ask for the reason, but couldn't it be that the larger loop somehow creates a virtually lower point of attack?

The Pic I had in my mind was unstrung...just saw the biiig loops. Now found this pic on atarn with a stringed bow (by Dennis Wong Chee De‎ATARN Traditional Asian Archery). Its all clear now. Good Trick! very intersting! Thanx
Edit: how (different) would a normal recurve bow behave with loops that big?

Yes, ideally the string loop  comes together right between  that section between the bridge and the apex of the  siyah  belly.

 A lot of modern Asiatic style bows don't have enough of a wedge to the siyah belly side and the string loops are a bit short.  The string rides against a square edge.
