Title: poundage?
Post by: bowmaster12 on August 13, 2010, 10:32:00 PM
i have a costum recurve that i ordered 55 at 27 when i recieved the bow it was marked 55 at 28 so hat shoudl put it at around 52 at 27 the other day just for giggles i put the bow on a scale pulled down to 27" and scale read 64 lbs i know that poundage on hand crafted bows isnt exact i was just wondering if the 12lb difference is normal?  By the way i love the bow its great

no. 12#'s is more than a normal discrepancy between scales.

I'm not so sure about 55#@28 = 52#@27

Might want to check your scale with known weights and/or against another scale. Just to be sure.

You can check your scale with some dumbells and yes 55@28 does equal very close to 52@27.

That seems way off,usally bowyers will go + or - 2# on what you order.12# is a big difference,like said I would check the scale or check your bow on a different scale just to be sure.

Missing  weight by 9 pounds (Ordered 55, got 64) is definitely grounds for sending it back.  But might want to check the accuracy of your bow scale first as others have suggested.

check your scale and calibrate it with a known weight.if its still off by 9 ship it back.jmho

check your scale, if it is right, and your bow if off 9 pounds the bow builder needs to fix the error. That is my take, Good luck with it. Let us know how this turns out.

Yep, if you and the bowyer are measuring draw length from the AMO location this would be light-years from what I'd expect. I've very carefully done these kinds of measurements using digital scales on all my bows. I typically check them at 28" (AMO spec), 25.5" -- my draw length, and 29" to see what kind of stacking is taking place. I've found 2.5-3 pounds of difference per inch of draw within these measurements.

I've noticed 1-2 pounds difference (usually lighter) from how the bow is marked.  The most accurate measurement vs. speced by the bowyer (my sample size is only 9) was a recent Schafer Silvertip I was trying out.

The depth of grip should be 1 3/4 in and weight should be pulled from the back of the bow. (front edge , to the arrow nock.  The poundage you gave is either a scale that is off or a bowyer mistake. It happens. If you love the bow then evidently the bowyer is a good bowyer. If so he should be able to at least drop the weight to a much closer margin. I'm doubtful that if he is a good bowyer that he would purposely send out a bow that is that much off. Some people could not comfortably handle that much more weight and in fact should not have to.God Bless and good luck. Steve

IMHO your scale test/verification weight should be near the weight you want to check.

I recently had 6 pounds taken off of a bow -- the bowyer made it right, I just ordered it wrong.
