i wouldnt want to have to do 50 with that thing,but i guess they work ok for one or two,now if it were a foot and a half longer and hooked up to a little electric motor you would have something
I made one of these with a carriage bolt, a pvc endcap and those black rubber bungee cords, cut up for fingers. I love it! My total cost was $12. Now I only tried to process six chickens in one day (I was by myself), but it works great for me! I believe someone here posted the instructions for making it. I've got a friend who built a whizbang and butchers 50 at a time, but this is a low cost entry and does a fantastic job on all but the wing tips (which pull out really easy). Karla
