Another poster mentioned driving his drill press from a Variable Speed
Drive (VFD) to slow things down to a speed suitable for tapping. I'd
like to look into this, but don't know which makes and models of VFD are
suitable. When I search on "variable speed driver", I get a flood of
large industrial units that far exceed the needs of an ordinary drill
press. So, what makes and models should I look into? TIA
