hey pal i made my own and i love it,,i welded a u shaped rod to a threaded bolt.
drilled a hole in my stand two nuts and walla a bow holder..its not perfect but what are you doing up there in the stand the jig,,,,your bottom limb goes between the u and holds the bow at the ready..if you want the bow at more or less angle just turn,and tighten back up. costs a whole 30cents or so..also you can slide rubber tubeing over
u shaped rod to pertect your bow.
