    Hey Sam, in your picture with the anchor plate, I'm wondering about the anchor sling. In my mind I would want a thimble of some sort on it. Seems that the sharp bend radius of the plate would eat up that tenex or amsteel. After you get some time on it let us know if it shows wear.

    If the anchor plate stays put, I don't see the bend radius as a problem. There isn't that much force involved, it's only two hand driven MA.
    I worry more about the rocking motion of the anchor plate under the alternative pull from the two MA hooked on it. The anchor sling will slide side to side in the hole and the fibers hate this sideway motion.

    Will do Rich.

    I thought about the plate sawing back and forth as well. When you pull on the blocks, all the load stays on the 3:1 anchor pulley, so there's very little movement on the plate. It does move a little, but it's not dramatic. Perhaps I'll make a quick video of it hauling something. . .

    Ok, I got it.
    I didn't read correctly your pics. I thought that it was 2 separate MA, like one to guy a sideliner and the second to pull it to the lay.

    Actually the blue MA pulls the red MA, so the stronger pull is always on the anchor of the red MA. The anchor plate has no reason to change its angle when loaded and the main sling should be fine.
    Nice setup.
