How can you calculate the draw weight of a bow without any equipment?

Calculating the draw weight of a bow without equipment is a challenging task, but with some careful observation and a bit of math, it can be done. Here's how:

1. Hang the bow vertically: Suspend the bow from a stable point, ensuring it is pointing straight down.

2. Mark the initial position: Tie a string or ribbon to the upper limb of the bow, at the nocking point (where the arrow rests). Mark the position of this knot on the string.

3. Pull the string: While holding the bottom limb of the bow, pull the string downward until it reaches the desired draw length (usually to your anchor point on your face).

4. Mark the final position: Mark the new position of the knot on the string.

5. Measure the distance: Use a ruler or measuring tape to determine the distance between the two marks you made on the string. This is known as the "draw length."

6. Calculate the draw weight: Multiply the draw length by the bow's "limb rating." The limb rating is a number stamped on the limbs of the bow, indicating the force required to draw the bow one inch. For example, if you measured a draw length of 28 inches and the limb rating is 50 pounds, the draw weight would be: Draw weight = Draw length x Limb rating = 28 inches x 50 pounds = 1400 pounds.

Note: This method provides an approximation of the draw weight and may not be as accurate as using a bow scale.
