  • Adjustable blade guide for a band saw
    Patent number: 10293420
    Abstract: Adjustable blade guide assemblies and their methods of use are described. An adjustable blade guide assembly includes two lateral blade guides arranged to support opposing sides of a blade and a rear blade guide arranged to support a rear edge of the blade. The blade guides are moveable relative to the blade. The blade guide assembly includes biasing members associated with each blade guide which urge the blade guides in a direction away from the blade.
