Well, I wasn't happy with the way the forks and rollers were set. So I made them wider. Lined the pouch with paracord. Put alittle more steel on the whole thing. Now it can take 550lbs worth of bands, and can fire a 30mm lead ball. And not that hard to cock, the pistol grip rests on the leg, well one hand holds the stok under the bearings, and the other hand draws the bands back (it's loaded after cocking). Note. the pic only shows 4 bands, was just for display.
