A new video is online!
This time, the pulley based draw length extension employed by the Bullpup Sling-X-Bow has been brought over to a conventional slingshot. 32 cm (13") of additional acceleration make this camo painted huge frame a true performer.
Both weapons are shot through the chrony, and the crossbow won by only a few percent.
The original design is from Mr. Robert Blair, it is called the "ComBow". The Slingshot Channel converted Mr. Blair's invention for the much faster flatbands, and also for the far more powerful "butterfly" shooting style. The result is a stronger slingshot, but it is also pretty bulky.
The video shows to more frames carved from dogwood, and a hand protection "glove". The slingshots are all used against a 75% empty 5 liter beer barrel. The beer was no longer drinkable, but good enough for the slomo cam to take some nice shots.
