Make powerful mini crossbow from old rusty leafspring, turn rusty leafspring into steel crossbow

I have seen people making a crossbow from bamboo but living in the city, its easier to find old rusty leafspring as limb or prods of my new home made mini crossbow. In my previous videos, I showed how I made Homemade medieval crossbow and it s bolts bolts but for the time being, not with broadhead. I like testing whether they are safe to use but not for sale. In this video I also show how I made crossbow trigger mechanism which was working great. With the prod made from leafspring, I can achieve around 80lb draw weight. I have also made it easy to upgrade the limbs. I build it to last so no hot glue or cardboard is used in this project. Actually it s not a cardboard or plywood crossbow but its stock is made of finger joint rubber wood. This is not a self cocking pistol crossbow I but I am satisfied with it anyway because although it is smaller this new mini crossbow has better powertosize ratio and much better handling making it ideal for target shooting or hunting small game, and c
