    I’m sure the wing nuts just loosened up on you. If your not going to be swapping wings, just replace the wing nuts with SS Nyloc nuts.

    The only time I have seen movement with the HOG wing on the plate is when the wrong slots are used to run the cam bands through. They need to go through the ones closest to the center of the plate. NOT the ones outside of those. The outside slots are actually not even necessary on the plate.

Using the ones closest to the center creates more of a "V" that with the ribs on the wing, hold the tank secure.
    I have two HOG wings on a steel plate and a soft pack. Properly strung and tightened, the cylinder doesn't move.

    ?? E.g. these: Soft Single Tank Adaptor (STA) with Book Screws are hard plastic tubes. "Built-in" ones tend to be flimsier, but they're not there to hold the tank, only to keep it straight while you're tightening the cambands.

    (Note to self: must stop by the hardware store and pick up a few nylocks for the bolts that came with Eric's plate -- the ones have are metric and don't fit.)

    Yep. Heaps important no to dive with loose nuts:D. Alternatively, to do so must be a fully a conscious decision :wink:

    dmaziuk, my hog gear wing has something similar, yet the tank would float side to side from time to time.

    locking wing nuts up next.


    Thank you to all who have commented.

    Have to add that one to my pre-dive check list slate.

    Think it should be part of a "buddy check"?

    Yep, can not say that this was not user error.

    I do not dis-assemble the back-plate/wing/sta with every trip.
    New SOP at the min is to go through the bolts if I stay with the STA...


    Thank you for your comments
