      To save me going and attempting the math have people got first hand experience of part wobbles being eliminated by getting rid of sprung mounted beds in favour of a fully nut and bolted solution?

      The risk is the weight of the bed and part being high enough to overcome the spring pre-tention and cause the bed to tilt under rapid accelerations.

        it sound like your springs are not strong enough.

        you could try replacing them with stronger springs like:

        or you could for a quick test replace the springs with wing nuts on the other side.
        that way the bed is ridged, but you can still easily adjust it.

        i went with the 2nd option for my bed.

          There's a better solution- instead of supporting the bed with springs, use springs to hold the bed down onto the levelers. Then just a little more messing around makes the bed kinematic.
