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 slingshot 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.

Looking forward to the project... :shock:
Curious though, how the bands would look like when attached to the pouches :P

I still have my Razor Edge compound bow. Not a bad weapon, but ever since my Liberty 1 arrived, it really only caught dust.

So I had this idea to use it as a part for a home made slingshot crossbow, much like the medieval style rubber powered model I am so happy with.

Took a whole afternoon, but it is now very functional. Medieval style trigger and rolling nut meets modern compound technology! The low letoff (15%) allow very easy trigger pull weights, making the weapon very accurate.

Finished the weapon, now I just need to attach a sighting system.

Here is a video that shows it in action:



It takes NO practice to hit with this thing, whereas a bow requires much training.

I also made another "Six Circles" shooter from Maka Mong burlwood, came out nice. See the pics in my blog!

This was probably the most exhausting, but also the most satisfying and fun vacation week I ever had.

It took four days to build the cannon, and then one more day of basic filming with the great guys from http://www.tapefilm.de before we brought the cannon to its playground - Tobias's wonderful farm.

He drove the weapon to his romantic apple orchards, on the hottest day Germany saw in the whole year... and then we fired it. Fired it. Fired it some more. Did I mention that we fired it a lot? :)

The performance of this thing is amazing. We did not exceed the strength of 36 conventional "hunterband" catapults (18 times the draw weight and twice the draw length), as it was getting tough to cock the mechanism even though we used long crank handles.

See for yourself:

We had a blast that day, even added a full blown slingshot tournament with several different challenges in the evening. I drank less beer than Tobias and even half cheated in one discipline (couldn't resist), but he nevertheless beat me 94:91  - the guy is just a great shooter, hats off.

Now I will go back to my job, a big show next week. But I am much relaxed, having achieved something I started to work on like 9 months ago.

Joerg, you were born a couple of millenia too late - the Roman empire might not have expanded to the extent that it did if the Teutons had you on their side!

I love the first car shot where the ball just goes through both windows without a care in the world :D
