Re: Light weight camping gear
When I was designing the hard points to mount my Video Camera mount on the lift struts, I wanted them inconspicuous because I didn’t want a possibly difficult conversation about them with the FSDO rep during the airworthiness inspection. This is what I did.The unit was made from a length of 4130 steel with an ID similar to the outside diameter of the lift strut.Three short lengths of 4130 tubing with ID similar to what would be needed for cutting 10-32 threads were welded at right angles to the larger tube – two at each end on one side and on at the center of the other side.Two more slightly longer tubes were welded at the two remaining free ends - these parallel to each other.
After welding, the assembly was slit with a band saw. Threads were cut in half the tubes and the others were drilled to 3/16” ID.The threads were cut so that the Cap Screws would be inserted downward on the shorter tubes and upward on the longer tubes when the lift struts were mounted to the airplane.This created a strong attachment point adequate for the video camera gimbal mount.However, if something heavy like a bicycle were to be supported, it would likely be wise to make the jury strut attachment welded tabs on this assembly rather than the aluminum ring tabs as well as possibly strengthening the jury strut attachment to the wing spars.

When mounting the camera mount weldment to the hard point, the bolts securing it also add a clamping force to the assembly. The longer two tubes project slightly through the fairings.In my application, there are two attachments on the leading lift strut tube for lateral stability, but only one on the aft lift strut which gives the fore / aft stability.Wires and control cablesfor the camera operation and gimbal movement were fed through an internal conduit.
