calculating poundage at X drawlength

(1/3) > >>

Aksel:
Hello, I thought of a something Iīd like to hear your opinion on. Maybe a stupid question but here we go:  Letīs say I am working on a straight stave flatbow and it is currently pulling #40 at 24" and it isnīt taking any set. I am not aiming for a very specific draw weight (this is the way I make most of the bows I am making for myself: experience guiding my decisions juggling limb width/draw length/wood type- quality/ length of bow, set taken etc = aiming for something I like to shoot, usually around 45 lbs +/- 3). This way of making bows might be a bit backwards, stabbing in the dark, but is there a way to calculate how much it will pull at, letīs say at 28""?

50 ish

Will B:
I usually see about a 3# increase in draw weight per inch of increased draw length, so I would predict that bow to come in around 52# @ 28”.

Pat B:
I think about 3# per inch.
 If, as you are tillering your bow only pull it to your desired draw weight when you reach your draw length you should have your draw weight and you haven't over strained your bow.

I’m the same way. I have checked a dozen of my selfbows and they all gain 2.5 to 3# per inch.
