B

Backlash: Play in a screw drive, so that turning the crank back the other way moves nothing for a moment. JessEm advertises a "zero-backlash" mechanism on its Mast-R-Lift II; that is the maker's claim, not a measured figure. Read more: 1/16 in per turn and 0.001 in: reading lift adjustment specs
Base hole pattern · also mounting pattern: The layout of screw holes in a router's base. Kreg's Pattern 1 has three holes (Bosch 1617, Porter-Cable 690 and others) and Pattern 2 has four (Porter-Cable 7518, Milwaukee 5625-20, Triton TRA001).
