Are you asking a question? Like a cheap tool to measure draw weight? If so...
A bathroom scale can work. Take a post with a platform set it on the bathroom scale...you can either zero out the scale or subtract the weight of the post from your final reading. Cut a notch in the top of the post, put your string there and pull down on the bow. The force it takes to pull down the bow will readout on the scale.
A fish scale can be purchased pretty cheap.
