If we move the fulcrum pin back (and up a bit) on the tiller, so that the lengths of the green lines are about equal, we find the the "legs" of the lever are not long enough to reach the pin.
In am inclined to think that there are two problems...
--The first is the the distance form max leverage point to the hooks is too long for the distance from fulcrum pin to the nut fingers.
--The second is that the legs are too short for this bow's draw length.
You might be able to make it all work if you move the pin back and raise the brace height to shorten the draw. If raising the brace is not an option, you are gong to have to make a goat's foot with longer legs for this bow.
