Hello Dan_ed, Yes, I understand, tiny set screws like this don't stand up to too much abuse. Often, an Allen Wrench has to be coaxed to fully seat into the screw before one applies any pressure.
I'm not sure about the TriPlanar, having never owned one (yet), but these screws may not be Stainless Steel, so even more care must be excersized, being a softer metal.
Wise suggestion about the left hand drill bits, and hopefully, our friend here will find the right person, and that he can carefully extract the bad screw.
Please keep us posted my friend how this all turns out.
I know it's a magnificent arm, and that you're wanting to enjoy it. Mark
