After several clumsy Sling-X-Bows, I wanted a compact plinking toy. A pistol!
Regarding the design, I always liked the Ruger MK2 .22 pistol. So I borrowed the grip/trigger look for my rubber based "competitor".
In order to have some amount of power, I turned the lock around (Stu's idea, in fact) and set for 45 cm (18") draw length (= total length of the weapon).
The trigger is really easy, just a lever that keeps the locks in place and releases them once the trigger is pulled. It is held back with a rubber band, this time it is not visible (under the lock plate).
The lock dowels are drilled off center, so that they are adjustable for different ammo size. Especially the small 8mm balls need very tight settings.
The three TB gold bands (2cm x 1,5cm x 11cm, effective length 8cm) are mighty hard to draw, about 12 kg draw weight.
The weapon shoots the 8mm steel ball with about 70 m/s, 230 fps. Not bad for the cold temperatures (freezing).
It is however more accurate with larger caliber ammo, maybe because the larger balls open the locks more evenly.
No video, it is already dark outside... maybe next week. This will give me time to make it nicer.
