the pictures of the small kinda pitifull grapple represent my first atempt at building a lightwieght simple rotating grapple it worked well for a couple of years , it did however keep breaking at the end of the cylinder and had only about 190 degree rotation , so I decided to build a new one around an old sander motor given to me by a friend this one uses a rubber coupler that simply pops out if you over do it on the twist and has 340 degrees of rotation.
