N601LL is 100 hours now and only remaining item was needing some up elevator trim for level flight and not enough up trim for a proper flaps down engine out glide.  The incidence of both wing and stab were good but as it does take quite some force to lift the elevator I decided to try a simple fix.  I put an eye hook on stab, drilled a hole in elevator horn and installed s-hook there.  Then connecting the two using #64 rubber bands discovered that nine was a good balance. 

Test flight successful.  Flies level at cruise with zero trim and flies hands off approach with full flaps, full up trim and throttle idle.

As below comment says.  All is well and the hook on stab was installed via rivnut installed in stab on the spar.  The actual goal was reducing the requirement for up trim in flight and having enough up trim with flaps down to allow plane to glide and proper rate of descent. To achieve this I used rubber bands to counter balance the weight of the elevator which does leave it in neutral position on the ground with engine off.

Doing cond insp and I replaced the rubber bands with freshly purchased ones.  So far all is well.  Will add yearly replacement to cond insp checklist.
