1/16 Bucyrus-Monighan Walking Dragline

Here is a start on the "Crows Foot" this is where the drag chains,dump rope socket,and drag rope socket meet. I made it out of 4140HT steel so it wont wear out dragging in the dirt.





Stepping down with a 1/8'' ball mill to make the taper.

Finally figured out an attack on the drag rope socket this weekend. Had to make it in two pieces then I'll Tig weld the halves together. Sorry for the ugly finish, I have lots of blending with the Dremel and Lots of deburring to do still on this one. I still need one more this size for the hoist and two smaller ones for the dump rope.
