Ken,
There is no drawing as such. I sort of made it up as I went along. Have done a rough sketch plus a few pics that should give you the idea. Essentially a normal 7/16 carbon stab tube fitted at 24% MAC. The carrier bearing is two bushes in an aluminium tube glued in the fuse. There is an aluminium cross rod fixed in the right stab that passes through the fuse and goes in to a stab adjustor. The end of the rod is reduced and notched. The stab adjustor is used to align the two stab halves and the notch engages the top grubscrew to retain the stab halves. The servo is mounted in a hatch under the leading edge of the stab. A carbon tube slides over the cross rod and a 4-40 threaded rod is bent around the tube and goes down to the servo clevis. No complicated linkages and no slop. The carbon tube protrudes outside the fuse by about 5 mm and acts as a spacer to maintain clearance between the stab root and the fuse. PM me if you want any more info.
