Re: Question about spindle direction for cuts

Stephen Bartlett

I have a Skil reversible electric drill that secures the Jacobs chuck in this manner. There is a left-hand-threaded flat head screw that goes into the end of the spindle inside the chuck, that secures the chuck from unscrewing when the drill is operated in reverse.

Admittedly, this is in a solid spindle, but the idea works.

That is just the first thing that came to mind...
