Title: How to measure weight at draw length on a bow?
Post by: Don Armstrong on September 18, 2010, 09:55:00 PM
Had a talk today about measuring weight at draw length.If you have a bow that is marked 45 lbs. @ 28", how would you check the weight @ 28". I have been taught to draw the bow to 28" measured from the string to web of grip, and read weight on scale . The gentleman I was talking to said he measures 28" from the string to the front of riser and reads weight on scale. Don

I read to the front of the riser but use his marker for measuring brace height.

God bless, Mudd

Mudd is spot on. Draw length is measured from the front of the riser. Brace height is measured from where the Bowyer/Manufacture sugests it should be measured from.

the depth of the riser on most bows is 1 3/4 inches from the deepest part of the grip to the front of the riser. Weight measurements are taken at the front of the riser or what is called the back of the bow. When WTT set up rules for testing the bows they took the measurements from the deepest part of the grip back 26 1/4 inches so that everything would be on an even draw playing field. That is because some bowyers might actually be only 1 1/2 inches to the front of the riser instead of the inch and 3/4 which would have given them an edge. But anyway its to the front edge of the site window. God Bless you all and have a wonderful evening. Steve

If the front of the sight window is 1 3/4" forward of the deepest part of the grip than yes, measure to the front of the riser at the shelf.  Drawing 26 1/4" to the deepest part of the grip will eliminate the need to worry about where the front of the shelf is and give you the true draw weight at 28".

I use an arrow marked at 28" and I put a clothes pin on the arrow so the side of the pin closest is covering my mark but just covering it. When I draw I know immediately by reading the clothes pin whether I've hit it perfectly or not. What I look for is the line on the arrow to barely be visible in front of the pin. I know then that I've hit 28 on the nose.

God bless,Mudd

I cut an arrow at 28". Then put a large fender washer behind th point. I draw until the washer touches the riser.

I agree with all that was said with measuring the weight of a bow from the string nock to the back of the bow "1 3/4 inch forward of the deepest part of the grip" but if this bow is to be used by you for instance instead of selling it or what not I'd be worried about the weight of the bow at your draw length instead of 28 inch.

I do the same and when I order a bow from a bowyer, I make sure he measure the poundage the same way.

I have never thought of this. That is so simple, it's genius.

]Good advice, I'm going to use this method, the fender washer is also good, good stuff here.
