Anyone using the Lone Wolf camera arm? If so........anyone upgrade and mount a fluid head to it? So I picked up a LW arm with the 3rd piece extension along with a Manfrotto 701HDV fluid head. I'm trying to find the most secure way to mount the fluid head to the arm. There doesn't seem to be a round mounting plate welded on the arm like you see with a Muddy, etc.........and I'm finding that when I just use a 1/4x20 bolt to just mount through the arm......it will come loose and I'm all of a sudden not getting the smooth fluid head pan action, instead the whole thing is pivoting on the bolt. Anyone else deal with this before? Suggestions?
