In preparation for the big event in two weeks, I started to put things together.
Today, I made the pouch for the monster. I want to use boule balls, 2kg, 3kg and 4 kg shot put as ammo. The pouch has to be big enough for the largest ammo type, which has 10 cm (about four inches) in diameter, solid steel. (The pictures show a 15 mm steel ball, typical larger size slingshotz ammo, in comparison.)
As the clamping mechanism needs some space, this means the pouch has to be about 50 cm long and 10 cm high.
I punched in 4 cm holes for the centering and also for the bands.
As I want to go up high in draw weight, I used very thick leather (3 mm), well made and totally strong (I had to hammer about 50 times PER HOLE on the hole puncher, which is really sharp...). I used two layers for a total thickness of 6 mm.
This meant the inner layer had to be cut shorter to end up even when the pouch is wrapped around the ammo.
The pouch alone weighs 200 grams, more than a 30 mm steel ball (130 grams)!
I will used looped Thera Band Gold, so I can simply add one more full width band when the shooting starts.
This pouch will endure crazy draw weights, and it will need every bit of that endurance.
