Good point - PLA is more rigid, with a Young's modulus in the order of 2x that of ABS. This would cut the backlash in half (to around 0.005"), but still not be rigid enough to drive the backlash down to the less than the precision of the indicator. I solved the backlash problem by beefing up the bracket's mounting to the lathe (2 screws near the sides instead of 1 in the middle) and gluing the slide to the upper part of the bracket instead of the lower.
