Measuring Draw Weight on Different Bow Designs???

[perry f.]

Just wondered how you measure draw weight on different bow designs? I put mine on a tiller tree, then using rope and pulley I pull to pre- measured distances on the tree. However, with different bow designs, distances will vary due to riser shape and how it sits on my tree. Just curious to see some other setups and hear some ideas. Pictures always help. Thanks in advance!

I have a hand held digital bow scale that records a peak weight.  I simply mark an arrow at a given draw length (say 28"), put it on the string along with the bow scale and draw it back until the marking on the arrow reaches the front of the riser.  I'll do this a couple times and take and average because that digital bow scale is a little touchy.

Hi perry,since i mess with self bows as well as glass bows I measure each riser and make a new mark on the tree to compensate for the different design.I also do the same as jsweka but with a spring scale.

I use a luggage scale I picked up at the hardware store. It records a stop at any draw point.  Here are pics that explain it better than me.  The one pic is sideways.    

The scale hanging by it's handle from two dowels in my back porch cover frameing.
 

Sideways, but how it hangs from dowels.  The slat of wood is marked with inches starting at the hook.  the bow string goes on the hook and the bow is drawn down along the measure slat.
 

As packaged when purchased.
 

The memory dial makes it easy to build an FD curve by recording a series of weights and then plotting them.  By drawing the handle down the measure slat you can pick any point between the back or face side of the arrow window to be your own "tru draw" point.

Best way I know of to measure different types of bows is to measure 26 1/4" from the deep part of the grip. This will give you an AMO length of 28". The AMO length gives you a consistent power stroke comparison regardless of the thickness of the bow. If you measure 28" to the back of the bow on a thick handle recurve and 28" to the back of a thin self bow of the same weight the self bow will weigh heavy because you actually pulling more than 28". Clear as mud.

What Ben said. Bows weights are measured at 28" which is measured from the string to 1 3/4" in front of the deepest part of the grip. This creates a standard regardless of handle design or depth. So check your draw weight with the bow drawn to 26 1/4" to the deepest part of the grip and you're good.

Here is my first set up on the tiller tree.
