linclogs - still wish I had more tools! 3/4" is too big for my equipment.

I have no idea what to expect for vibration of this stand,
your thoughts on: 1/2" allthread (cut to length), 2 nuts, flats, and locks, drill and tap top end for 10-24 and hole for control rod.

This would allow vertical post move if necessary for different linkage location with only a new hole in the base.

Is there a preferred order of drilling the intersecting holes for a clean inside junction? Maybe it is NBD but have feeling you may have more experience and knowledge.
