TPU/FLEX slingshot pocket/pouch adapter for compound trigger

It's well known that one of the main problems in slingshot shooting, posture aside, is properly releasing the pouch. Small asymmetries in the attachment and awkward movements of the thumb and forefinger cause inaccuracy and poor repeatability of the shot.

To overcome these problems, you can try using this adapter made of FLEX or TPU glued to the leather of a appropriately prepared pouch. 

First, soak the leather pocket in hot water for about 15 minutes, until the leather stops bubbling. Then, place an 8 mm steel sphere in the pocket, ensuring maximum symmetry.

Using the two cylindrical molds, secure the sphere in place and insert it into a clamp, tightening everything. Let it dry for a few hours and then release the pocket, which will now have taken the shape of the sphere.

Meanwhile, prepare the surface of the FLEX by roughening it with the Dremel.

Now, spread neoprene leather glue (Bostik) on the bulges of the pocket and in the cups of the FLEX piece.

Important: Wait at least 20 minutes before gluing the parts.

Matching the pre-formed pocket cups with the recesses in the FLEX piece, glue the parts, always paying attention to symmetry. Finally, using the two parallelepiped molds, press firmly with the clamp. Let everything dry for at least 24 hours.

Now the modified pocket is able to accommodate 8-9 mm clay or steel or rubber spheres without letting them fall during the tensioning of the rubber bands and the release of the pocket, manually or via a compound trigger will be much "cleaner" so that the accuracy of the shot will be positively influenced.
