When mounting the 3.5" Q to the Tristand baseplate, tightening the knurled 1/4-20 steel screw will bind somewhat against the aluminum, making it difficult to determine just how much to tighten the screw. I applied a small amount of Molylube at the shoulder of the screw where it contacts the underside of the Tristand baseplate. This gives a much improved "feel", and the correct amount of torque is much easier to judge when tightening. How tight is tight? I don't know either! It just feels better to me, and hopefully, helps to prevent over-tightening the screw.
Happy New Year and Clear Skies to all,
