Here are my revised plans for a one handed staff sling. I tried this a few years ago but using a Y-shaped wire end that didn't work very well.
The staff is a 1 cubit (elbow-to-fingertip measurement) long, 1 inch diameter piece of oak mop handle. The grip end is wrapped in soft, waxed leather with a ski pole styled lanyard anchored just above the grip and at the "back" of the weapon (near the thrower's thumb webbing & opposite the string notch). The launch end has a deep, wide notch on the leading edge of the tip to control & give direction to the strings. This notch may be reinforced by fitting an appropriately sized (inner diameter) peice of metal tubing over the tip & extending at least 1 inch below the lowest point of the notch; secure tubing via nail/screw through shaft & bend tube wall flush into the notch & file smooth.
One end of the cord is tied through a hole in the staff, about 1/5 inches below the tip. Countersink the holes so that the string doesn't fray or wear. Run the cord up through the notch, over the top & back down the back of the staff. The pouch should be roughly even with the end of the staff. Place your hand through the lanyard ski pole style & run the other cord back along the first & down the front to the end. This gives the thrower an adjustable knot end. Find which finger makes a good release finger for you - I use my little finger. Tie a knot that is movable in case you wish/need to make adjustments, such as a figure 8.
The slinging motion I use is a overhead, bullwhip type action with a follow through. Side arm is possible but is dangerously inaccurate. I havn't tried cross-body, greek or underhand.
I have only used computer mouse balls & similar size/weight stones & clay glandes with this sling. I have also had good experiences using this sling in moderately thick cover where a regular sling might tangle in the brush or branches.
A quick & less expensive version may be made from nylon cord, a pouch, cloth athletic tape for the handle & a PVC pipe shaft. Or an appropriately sized, forked branch with the cord tied below the fork.
Let me know how it works for you! The tubing & oak handle are out of my budget until my doctor permits my return to work. My previous version worked well with the exception of the wire tip bending, twisting etc.
**Note: B & C are reversed in the drawing. I will correct this soon. Thanks 4 the catch Tint.
