Am I missing something here with the diametrical configuration of the repro scopes and mounts?
Is it that the 1" diameter of the tube is incorrect
or that the 1" diameter of the bored hole in the cradlke and caps that it incorrect or just out of alignment that is crushing or distorting the tube
Surely, if the geometry of the 8x taper lock cradle cap clamping screws and corresponding holes in the caps is correct, then you physically CANNOT overtighten them beyond a minimum torque (I forget what it is now - 5 or 8 ft/lbs? - have to look in an old Machineries handbook.......) that is insufficient to crush the tube as the screws will lock up in their own taper.
Any chance of some pictures of your damage Norton?
Or am I going off the subject into a non related area?
