It sounds to me as if you have progressed with your bow-making in a well thought-out manner.
I don't know the technicalities of all the specs, but I do know that bows require a certain finesse in workmanship to perform as expected.
The fact that you are willing to do this for your own gratification is awesome. I have always admired bowmen, and even moreso, admire someone who can make their own..
Are you (have you????) been taking photos of the progress? I would be interested in seeing the steps and the finished product!
In the meantime, please accept a hug and a pat on the back for your work!
I have begun photographing now that my attention has turned to the big bow.
I will post the images once the project is complete -no matter how it turns out- and write up a project summary.
