DIY: make pallet crossbow from leafspring , Rock throwing crossbow from Renaissance, make stone bow

In my previous video I made a mini medieval crossbow and uploaded on this channel. I am glad to see the good result as many people have watched, liked the videos and subscribes to my channel because of it. This time, I would like to make another attempt to produce a stone bow, pallet bow, Rock throwing crossbow from Renaissance. I made the stock from tropical hardwood, the prod from vehicle leafspring. I designed it to shoot marbles. It’s quick and easy to load and fire with very good accuracy with the foresight and back sight though i don’t designed the prod to be very strong from long range shooting. this video is just an attempt to copy Renaissance’s stonebow or rock throwing crossbow. It’s not an attempt to compete with modern slingshots. It’s just a love for history and arts though I can’t make it as nice as the real one. I intentionally made the prod lightweight for some safety reasons. But with a much heavier draw weight prod, maybe it can be more powerful than most slin
