Thanks Mike, very well done.
I made one today also, after much thought, I figured it would be wise to have the stringer rope run across the top of the limb tip instead of all the weight being applied to the leather only.
Got me as sweet piece of 12" x 24" x 5/32nd thick leather and some 3/16th" nylon rope and tried it.
This is the first one I made, needs the corners cut at an angle or rounded to shape it up a tad but works great.
This one is for the bottom limb, I made the top limb a tad different and smaller, forgot pichers..
The limb tips ride inside the rope on the sides too.
