BRM Announces Engine Hones for Cylinder Surface Finishing; Recommends Flexible Honing After Cylinder Resizing

Share Article

Brush Research Manufacturing (BRM), maker of the Flex-Hone® tool and a full line of industrial brushes, announces flexible engine hones for cylinder reconditioning. Engine builders use rigid hones for cylinder resizing and flexible hones for plateau finishing, a surface finishing technique that creates a cross-hatch pattern for optimum lubrication and reduced engine wear.

Brush Research Manufacturing (BRM), maker of NamPower™ brush tools and a full line of industrial brushes, is announcing flexible hones for cylinder surface finishing. BRM’s Flex-Hone® tool produces the ideal cross-hatch pattern on cylinder walls, improving lubrication and reducing engine wear. Rigid hones are recommended for out-of-round cylinders, but cannot match the plateau finish of the Flex-Hone®.

Flexible Hones vs. Rigid Hones

In a technical article called “Evaluating the Cylinder,” the website Small Engine Information describes some of the differences between flexible hones and rigid hones. With their continuously-aligned stones, rigid hones are suitable for heavy-duty material removal. After an engine cylinder is resized, however, the cylinder walls need a series of shallow scratch marks to help retain engine oil.

For optimum lubrication, this cross hatch pattern should contain a uniform series of peaks and valleys. Rigid hones can create uneven valleys, however, so engine restoration specialists prefer flexible honing tools instead. Self-centering and self-aligning to the bore, the BRM Flex-Hone® mounts in a handheld electric drill and is easy-to-use.

Cylinder Honing and Plateau Finishing

Available for any type or size of cylinder, the BRM ball hone uses a low-temperature abrading process that’s ideal for applications such as surface finishing, deburring, and plateau finishing. BRM engine hones come in small sizes, too, and can be used on many two-stroke engines that would not accommodate a rigid hone, as the “Evaluating the Cylinder” article explains.

At WeekendFreedomMachines.com, an unofficial website for John Deere enthusiasts, members of the Restoration Forum agree. For out-of-round and out-of-taper bores, forum members recommend using a rigid hone to correct cylinder geometry. For a superior surface finish, however, engine experts know that flexible cylinder hones from BRM impart the ideal cross-hatch pattern.
