Does Burnerd use a weird type of lathe chuck key? I ask because it doesn't look like a pure square drive. It's a model A38 10" four-jaw independent chuck. See:
Secondly, for those who have changed the set screws in their Phase II quick-change toolholders did you find them to be metric? I measured the screws in mine and they *seem* to be M10 1.5 x 20mm long. Mind you, the screws are not exactly this size but they are closer to that than 3/8-16 x 3/4". They measure 0.386" in diameter, and are 0.779" long. I don't have an great way to measure the thread pitch but my inch pitch gages don't fit exactly. Over 9 threads it averages about
0.059" peak to peak. Pretty close to 1.5mm (1.4986mm). And 16TPI is (should be) 0.0625".So what say you?
