My backlash is also .015. My major complaint was that the handwheel would drop back under it's own weight when the grab handle was in the 9 oclock position. I did all the adjustment steps that can be done without disassembly (tighten lead nut lockscrew and tighten handwheel spanner) and although my backlash is still .015 the handwheel at least stays put. Thanks to all for your input.
