Frequently Asked Questions
No, a jack plane is traditionally a manual hand tool, though the term sometimes refers to the role in a sequence, which can be done with powered equivalents.
Typically, a jointer plane (or try plane) is used to perfect the flatness and straightness, followed by a smoothing plane for the final surface.
Not ideally. Its design is for stock removal. A smoothing plane or cabinet scraper is better for a finished surface ready for sanding or polishing.
The term 'jack' here derives from the general-purpose meaning, as in 'jack of all trades'. It's a versatile, all-round plane for intermediate work.
