My beloved Juliet’s were accosted by my limited budget, substandard lens purchase, and carelessness. The right orbital screw will no longer bite thread. Does anyone have some ideas/advice about this? I’m pretty sure the threads in the tapped screw hole have been sheared off. I am not a machinist but I am pretty handy. I feel like I lost a part of myself. Somebody please help if you can, and I will sing the praises of your deeds to the edges of the Earth.
